Hi Hamza, 

 

Short answer is yes you can. Does the different vlans have different zones ? 

If they do just apply the src zone as required in your rules. 

If they don't can seperate it using an address object range if the vlans have different subnets. 

ref : 

here's a link of a guy setting up a pa-200, using vlans and rules for the vlan

here's a link for creating address range if no seperate zones for the vlans

Hi @hamza_ineos,

 

Yes you can. 

Just use different zones per vlan and you can control your policies based on those zones.

The following getting started guides should be very helpful for you :

 

Getting-Started-Layer-2-Interfaces

Getting-Started-Layer-3-Subinterfaces

Re: Apply policy security on vlan

thank you very much brothers

i still have some questions plz, we have 2 scénarios in our deployment:

 

1-creating the vlan in PaloAlto firwall, and then manage it from the firewall.

2-or create the vlans on the cisco switch, in this case can the firwall apply the security rule on the vlans created in cisco switch ? (Important question).

 

witch of the this 2 sénarios is the best practice ?? 

plz if it's possible give me what the advantage/disadvantage of creating vlan on paloalto and not on cisco switch !!

Hi @hamza_ineos,

 

Personally, I don't think it's a matter of which is best practice ... 

Both are valid ways to configure.  You'll just need to decide on a design that best fits your network and configure the firewall/switch accordingly.

Hi @hamza_ineos,

 

Yes, you can use tags and zones for this.

It's explained in the 2nd link I posted earlier : Getting-Started-Layer-3-Subinterfaces

Re: Apply policy security on vlan

Hi @kiwi

Thank very much for help!

this tutorial is very nice, but i have a question, i see in the toturial that we must give an ip adresse for the vlan(in paloalto), this adresse ip is the same that i gave it to this vlan when i created in cisco switch ?

 

ex: i create a vlan10 on cisco switch with ip adresse: 10.1.1.1/24, then i must create a subinterface in palo alto with the tag 10, and the adresse ip : 10.1.1.1/24 ??

 

thanks a lot
