Hello Everyone,
I'm new on Palo Alto Configuration,
I would like to know if it's possible to configure 2 zones for the same physical network.
Use case:
Ethernet 1: Zone Servers: ip: 192.168.80.254/24
Ethernet 2: Zone internet 1 : 193.1.1.254/24
Ethernet 3: Zone internet 1 : 193.2.1.254/24
I would like to have another network 192.168.90.0/24 so that I can chose let's say
network 192.168.80.0/24 goes out on internet through Ethernet 2 and network 192.168.90.0/24 goes out on internet through Ethernet 3
How is that possible when I have only cable connected to the switch having both networks (192.168.80.0/24 and 192.168.90.0/24)
Regards

Hi support.securalis ,
Yes that is possible. To address your 1st question, you can configure either secondary IP for .90 subnet on ethernet 1 or configure subinterfaces on Ethernet 1 for both .80 and .90 subnets.
To route the traffic you will need policy based forwarding, where you can say .90 subnet will take ethernet 3 when going out. And rest of your network will take regular route via Ethernet 2 (or vice versa).
Hope this helps. Thank you.

Just to elaborate on what ssharma said:
If the 192.168.90.0/24 subnet is also coming from Ethernet 1 then yes, you will need to use PBF
However, if 192.168.90.0/24 is coming in from another interface, you can set up a virtual router for each path with the appropriate routes.

Thank you very much. I did it like configuring a second subnet on the same interface.

Since you are looking to have each subnet use a specific ISP, you could simply put the ISP plus subnet into their own virtual router. This way no special configuration for PBF is needed.
Create two virtual routers
Put each ISP into one VR with a default route
Put the servers subnet into VR 1 and the user subnet into VR2

Can you do that via a single interface?

Sub interfaces are considered separate interfaces and can be placed into different virtual routers and zones.
