PA3250 - L2 - L3 interface communication

L0 Member

Hi Team!


I have simple topology ( pls see at the picture). 

I configured eth 1/1 ( for PC2) as L2 interface, but without Security Zone. 

I want to ping from PC2  - default Gateway (AE1.121) and PC1. 


Is it possible to set up Palo Alto like this?


Pls, give me details, I can't find any  use cases with the similar configuration.


Thank you in advance.

I don't think the L2 port will be able to communicate with an L3 interface. 

When you have an L2 subnet and you want communication in/out, you'll need a vlan interface, not an L3 interface.

Why are you connecting a PC directly to the firewall?

You will need a zone and policies that allow that traffic. Check the logs to see why the traffic is not making it.
