Ad Hoc Conferencing

Conference Cant get Any Easier  ;D

I already explain in earlier blog the other Conference Feature Meet-me and in my Believe Ad-Hoc is the Advanced feature of Conferencing

in Ad-Hoc the Initiator of the Conference which is the Controller would have the  ability to view the List of the Other Parties, to Remove Some of the Parties. Also you can provide this  Feature to the other parties to have same capabilities of the controller

First just like Meet-Me you need to have conference resources available on you router before you can use any conference features i already explain how to configure a Conference Bridge in earlier Blog Media Resource Group

no other configuration needed

so to start conference first i will go to My Cisco 8941 phone and Make call for the First Parties which in my example is extension 7188

Untitled

After the first parties answer then I Press the Conference Button

Conference Button.png

on the 8941 and Call Second Parties extension number 9059

IMG_6702

After 9059 answer then press Conference Softkeys to Add him to  the Conference

IMG_6705

And it’s now everyone join the  Conference and you can add as many user that your Conference Resource can support

You can view the List of Parties by press View Detail Softkey

IMG_6707

Detail

Also you can select a user and remove him from the Conference

IMG_6709.JPG

its a really great feature and user will not have to go through System Administrator to ask for a Number to call like Meet-me Conference were you need it

to adjust your conference to protect your self from toll fraud you can configure the call to be terminated once the controller drop the call

Go to System – Service Parameter – Select the Server and Choose the service (Cisco CallManager ) then go to Clusterwide Parameters (Feature – Conference)

Drop Ad Hoc Conference : When Conference Controller Leaves

10

Also if i want to other Parties non-Controller to View List of Conference parties and Remove other Parties i will go to System – Service Parameter – Select the Server and Choose the service (Cisco CallManager ) then go to Clusterwide Parameters (Feature – Conference)

Advanced Ad Hoc Conference Enabled : True

20

Also you can increase number of Parties to join conference, the default value for this Clusterwide Service Parameter is 4.

Meet-Me Conference

So i got request from one of the Top Manager in Jaguar Land Rover to have a way to make a conference in his phone for Daily basis

will conferencing one of the most important things in any Enterprise this days,  it save traveling and timing and get to the point ASAP.
Cisco made the implementation of conference easier with Meet-Me Conference so let me guide what you will do when a user Ask you to get to a meeting

So lets go to the Configuration part

First requirement is to have conference resources available on you router before you can use any conference features i already explain how to configure a Conference Bridge in earlier Blog Media Resource group

so after that go a head to Call Routing – Meet-Me Number/Pattern – Add New
Choose a unique Number Ex.: 9876 and partition

1
in case you have a custom Softkey template Then Add the Meet-Me Softkey to the Off-Hook state
(another option is to configure the Meet-me as a button)
Go to Device – Device Settings – Softkey Template – Add new
i named it (Meet-Me)
2
Then Go to on the right corner to Configure Softkey Layout
then select the state Off-Hook from drop down
and Move the Meet-me to the Selected Softkeys and Save
3
Now go to the phone were  you need to initiate the Meeting and Assign the New Softkey template to it which we configure
4So to Procedure
go to the Phone to initiate the Meeting
while the phone in  off hook state press softkey meet-me and press the Number which we configure earlier 9876 which is Meet-me Directory number
IMG_6689
After that put the Meet Me unique number 9876IMG_6690
and Like that you enter the Conference RoomIMG_6691
now go the other Parties and Let them just call 9876 simply like they dial any directory number

and Walla they Enter to the Conference Room3.JPG

and that’s a wrap

**the meet me can hold as many Parties as your resource can support**

Palo Alto Site-to-Site VPN

OMG one of the best last moment for me in 2018 was last October when me and the Crew attend GITEX the world of technology in Dubai (United Arab of Emirate)

1

IT’S THE BIGGEST & BOLDEST TECH SHOW IN MENA & SOUTH ASIA

attendees from 120+ countries and global media outlets in unpacking the big conversations and latest solutions around AI, blockchain, robotics, cloud and other mega trends, as GITEX takes you on a multi-sensory experience of Future Urbanism across 21 halls with 4,000 exhibitors across 24 sectors.

and here im going to tell you my new article

So Let me tell you, in my years in network i have never implemented a Site-to-Site VPN and i mean never ever in any product wither Cisco, Juniper or Palo Alto

so i spend reading the Last Couple of days reading and study about it and Thanks to My Mentor Mr.Keith barker from CBT Nugget https://www.cbtnuggets.com/trainers/keith-barker he Got His own way to Make the most Difficult thing Easier than you can imagine.

you can find his Palo Alto video in this Link https://www.cbtnuggets.com/it-training/palo-alto-networks-firewall

So Let’s Start, i have 2 Site

One with Palo Alto VM Machine and the Second Site i have Cisco Router 2811

I put Simple IKE Phase 1 and Phase 2

IKE 1

DH Group: group1

Encryption: aes128

Authentication: sha1

Lifetime: 5 Minute (300 seconds)

IKE 2

IPSEC Protocol: ESP

DH Group: group1

Encryption: aes128

Authentication: sha1

Lifetime: 5 Minute (300 seconds)

So First Create a VPN Zone Like i Show you in the First Blog

go to Network – Zones – Add new

999.png

Then create the tunnel interface

Go to Network – Interface – Select the Tunnel tab – Add new

I Choose number 1 and i have one virtual Router and Select the Zone (VPN)

1

Give the Tunnel an IP Address under the IPV4 tab (10.1.1.40)2

Now Lets Create the Phase 1

go to Network – Network profile – IKE Crypto – Add new

i Configure it as my scenario

DH Group: group1

Encryption: aes128

Authentication: sha1

Lifetime: 5 Minute (300 seconds)

3

After that i create the IKE Gateway

Go to Network – Network profile – IKE Gateways – Add new

Select the WAN interface and Choose static for my Peer since  i know the IP Address and Put the Pre-shared Key (ccieroot)

4

go to Advanced tab to Select th IKE Crypto profile and Choose the IKE Crypto for IKE1 i Created Earlier5

Now to IKE2 Configuration

Go to Network –  Network profile – IPSec Crypto – Add new

and Same like IKE1 we will follow out Scenario

IPSEC Protocol: ESP

DH Group: group1

Encryption: aes128

Authentication: sha1

Lifetime: 5 Minute (300 seconds)

6

After that i will Configure the IPSec Tunnel

Go to Network – IPSec tunnel – Add new

Select the Tunnel interface, IKE Gateway and IPSec Crypto profile7

Now i Create a Static Route to Site 2 LAN

Go to Network – Virtual Router – Select Our Router – Edit – Static Route Tab – Add new

type the Destination of Site2 LAN and Select your Tunnel 1 and Type Site2 Tunnel Interface IP Address as My Next hop

8

Last Part of Palo Alto is to Configure Security Policy Rule

Go to Policies – Security – Add new Choose a name and Rule type Universal also Interzone could work8a

Choose Source as the Tunnel Interface Zone which was (VPN) Zone8b

Select my Destination As (LAN) so Ping from Site2 to me Work Perfectly8c

and Choose Action as Allow

22

Again do the Same to My Palo Alto user in Site1 to Allow their Ping to Reach Site2

19

Source as LAN

20

Destination As VPN21

Now if you go to Network Tab – IPSec tunnel you will See the Status is (RED)9

So Lets Start now in Cisco Side To Turn that light Off

First i Configure my Public Interface which Happen to be My FastEthernet  0/0 and My Loopback which my Internal Network

10

Next i Configure my IKE Phase 1 which Same Configuration to IKE1 in Palo Alto

Dont get scare if  you show Run and you Don’t See group1 in the Configuration ;D

11

and Configure the Key Password and my Peer Address12

After that i Configure my IKE Phase 213

and Configure my IPSec Profile14

Then i Configure my Tunnel Interface15

and Last but not Least i Configure my Route to Site 1 LAN16

and now when i get back to my Palo Alto i see the Status turn Green17

Also you can check the status on the Router

900

Now i ping from my Router to Palo Alto LAN Interface and it’s Work Perfectly

18

i Also Login by my PC and i Ping the loopback and ti work perfectly23

Palo Alto Captive Portal

Well let me tell you what happen this week
I saw one of our work mate login in his private Laptop to internet and download is so high and his user don’t show in the monitor page.

So there is a feature available in hotel and Internet Cafe and its a great feature to control who is going and coming and sometimes to which website
This Feature Called Captive portal

let me guide you in the configuration
the requirement 1, 2 & 3 available in earlier blog you can click in each component and it direct you to the page
1-LDAP
2-Authentication Profile
3-Certificate
4-Certificate Profile
5-Enable Captive Portal
6-Captive portal policies

So start from Step 4 to create a certificate profile
Go to Device – Certificate Management – Certificate profile – +
Choose Name and Select the User Domain
then under the CA Certificate Add your Cert that Created in Earlier Blog
50

60

1
Then Go to Device – User Identification – Captive Portal Settings – Edit
Make Sure to check Enable Captive Portal
Choose the Authentication Profile That we Created in the Earlier Blog
and Choose Mode Redirect
and in the Filed of Redirect Host put our LAN IP 192.168.250.250 so all traffic forward to that IP2
Now Lets Create a Captive Rule
Go to Policies – Captive Portal – +
Choose a Name
3
Then Select the Source as Inside4
Select your Destination as the Outside WAN5
After that select Your Service as HTTP and HTTPS also you can add a URL Category if you want to strict the Captive Portal to specific web sites
6
Choose the Action web-form 7
Last thing go to the Management Profile and make Sure you check the Response Pages so the user would be able to receive it
Got o Network – Network Profiles – Interface Mgmt – edit my Profile which i created in an Earlier Blog

Now lets go to the user PC and Open a browser to google Web Site
as you can see it direct me to 192.168.250.250 in URL
Click on Continue to this website (not recommended)
10
It will ask you for your Username and Password
I will put my LDAP Authentication Username and password20
Now it Login me30
and Walla im there40

 

Note: in the newer version of Palo Alto Captive Portal Policy is Called: Authentication Policy and Web-form is changed to : default-web-form

Blocking Youtube Using Palo Alto URL Category

Youtube
The Bandwidth Killer
to be honest i learn a lot from youtube whether cisco configuration or paloalto or even other things
but during work hour many user using youtube to hear songs, watch a movie trailer which kill the internet bandwidth so i explain earlier how to block facebook using APP-ID
but Youtube APP-ID is little diffrent cause it depend in google-base which will forbid google website too
so URL Category may save the Day
this remind me of Microsoft TMG

So first let create a URL Category
Go to Objects – Custom objects – URL Category – add new
(Youtube)
Add URL (www.youtube.com) Also you can add more (*.youtube.com)
1
now we create a security policy
Go to Policies – Security – add new (Stop Youtube)
2
Select the Source Zone (inside) and the Source Address (My Laptop IP  Address)
3
Select the user aysar.mohamed (Me)4
Select the Destination as my Outside Interface5
Select any in Application tab6
well here we go
in Service/URL Category we select the (Youtube) Category that we create earlier7
put the Action to deny8
now when i try to open Youtube i got the deny messgae ;D9
As you can see from the log i got the (Reset-both ) Action in rule of Stop youtube 10a

;D

Blocking Facebook or Facebook Chat Using Palo Alto APP-ID

First i have to apologize cause this going to be a long Trip and it my fault i didn’t research it will but to deny an SSL traffic which used by facebook first you have to read what inside it, in another word (Decrypt it)

So i’m here rewrite the article again and just add the Decryption of the traffic before it forward to the intended site
First we need to create a Certificate on Firewall
Choose a name, Common name and Check the Certificate Authority
and the Certificate Attributes then Click Generate

1
Now Select the Cert to Edit and Check the Box
Forward trust Certificate
Forward Untrust Certificate
trusted Root CA
22
Then Export the Certificate as (PEM)
2
Choose Place to Save it
3
and as you see it download it in my Download Folder
4
Second i will go to my laptop to import in
Go to Tools – Internet Option – Content – Certificates5
Go to trusted Root Certification Authorities Tab – import6
Press Next
7
Browse to my Certificate8
Choose to place it in the Trusted Root Certification Authorities9
Press Finish
10
it will give you a security warning just press yes11
and import is successful
12
you can check it under the Trusted Root Certification Authorities Tab
13
Now get back to Palo Alto and Configure the Decryption Polocies
Go to Policies – Decryption – Add14
since this is a lab i will Choose Any as the Source
15
Also Choose Any as the Destination 16
i can Adjust under URL Category but since this is a lab i will configure it as Any17
Under option Tab i select the Action as Decrypt and Type SSL Forward Proxy18
Now i Check Gmail and here its Secure from my PA-CCIEROOT which is my Palo alto Common Name20
Also my facebook is Secured 21

;D

Now to the Part that everyone kept ask why Aysar it aint working
your article is worng
will i hope it work now

So as i said earlier unless you work in Marketing then you don’t need any Social Website
so Aysar Mohamed (ME) is an IT guy and i want my self to do IT Work and stop playing around the Facebook (i am sure my manager agree in  this point)so let’s do it

First go to Monitor – Logs – traffic and as you can see it full by Facebook logs by Aysar and it depend on one Application (facebook-base)

1
So let go to Policies – Security – add new (Stop facebook)91
Select the Source Zone (Inside) and Source Address (My Laptop IP Address)3
Select my user (Aysar.Mohamed)4
Select the Destination my outside interface5
then here choose the application (facebook-base) which appear in my logs90
Now Choose action to deny
92
Make sure to move this rule to the top
7
As you can see now i cant open my facebook at all and it give me this error7a
and if you go back to the logs you will see the action (reset-both)8

Now what if i want Aysar to view his Facebook but don’t want him to Chat with Anyone
Easy go back to my (Stop facebook) Policy change the APP-ID to (facebook-chat) and save9
some application can’t just stop by choosing the APP-ID you need to select also what it depend on
so highlight the rule and go to the application tab and choose facebook-chat and right click and choose (Value) to see what its Depends on.
so for facebook-chat it depends on
facebook-base
mqtt
Now If i select facebook-base it will also block facebook page Also
so here the trick
10
Add only mqtt
11
Then in my Second Rule (Aysar Allow) i will add to Alow the facebook-base12
under Application i will only add the facebook-base13
Now i can go to my facebook but as you can see my Chat is Dark (Unable to connect) 15
and as you can see in the Logs it block the facebook-chat14

;D
(let me just note this it only worked with me cause the Decryption was in the Palo Alto earlier)

Happy Friday Everyone

Palo Alto High Availability

Down Time is not Acceptable in Any Environment
And here were the term High Availability comes to play.

To Configure the high availability in Palo Alto you need to have Two Links in each device, one for the Control Link (HA1) and one for Data Link (HA2)
both Palo Alto Device Exchange a hello message and a Heartbeat through the Control Link (HA1). if any of that not receive the Backup Palo Alto Peer will Assume that the Active Peer is Down and Take Control
(Note. this Scenario is on Active/Passive Mode)
be Aware that Both Palo Alto Device should have the Prerequisite:
1- Same model
2- Same interfaces
3- Same PAN-OS
4- License

well i’m working here on PAN-OS 7.0.1
My Active Palo Alto IP Address: 192.158.208.222
My Passive Palo Alto IP Address: 192.168.208.111

So i Show you earlier how to configure Palo Alto from scratch in the earlier Blog
Now I add extra Network card for the (HA1) & (HA2)
So to Configure the Palo Alto interface
Go to Network – Interface – Select interface
Ethernet 1/3 will represent HA1
Ethernet 1/4 will represent HA2
1

2
Now to Peer Configuration
so i Give the Active Peer IP Address
192.168.209.140 (HA1)
192.168.209.142 (HA2)
and for the Passive Peer
192.168.209.141(HA1)
192.168.209.143 (HA2)
Go to Device – High Availability – General Tab – Setup settings
Enable HA and choose a Group ID and fill the Peer IP Address and choose the mode
3
Then go to Control link (HA1 Configuration) and Choose my ethernet 1/3 as the HA1 and put the IP Address 192.168.209.140 and Netmask
4
After that i go to my Data Link (HA2) and Enable the Session for Synchronization and Put the IP Address i choose earlier 192.168.209.142 and Netmask and Gateway and for my Transport i select IP
5
Now to Election setting and to make Sure that 192.168.208.222 is the Active one i have to Put a Lower Priority
The Default is 100 so i Configure it to 90 and select Preemptive and heartbeat Backup
6.png
now go to Dashboard Tab – widgets – System – and Select HIGH Availability
so i can see the status in the Dashboard
7
and as you can see the status is so red
9
Now in the Other Peer i need to Configure the Same Interfaces for HA1 & HA2 and same configuration for HIGH Availability except the IP Addressing and for Election Setting i will just keep it the default
and then go Back to the Active Peer 192.168.208.222  and you will see the HA1 & HA2 turn to Green and now choose to Sync to Peer
10.png
It will Ask you to Overwrite Peer Configuration just Select yes
11
And now All our Configuration is Synchronized
13
Go to Passive Peer and you will See the Local Peer is the Passive
and the Active is 192.168.208.222
14
if you check the Passive Network interface you find it’s Red 15
And now to Test it i will ping  8.8.8.8 Non Stop and power off the Active Peer16
and as you can see it just took only 3 request timeout which less than 6 second and user will not notice itqqq
and if you check the System log in Dashboard you will see your passive peer notice the HA1 Control Link Went Down and the Passive become the Active
20
And our Red Interfaces Become Green21

;D
