Region Blocking

L2 Linker

Hello everyone.


I want traffic only from my own region. I want to block all other regions. How to do this process in a simple and short way?

Hi @Fagani ,


We have option in Palo Alto to configure security policy based on source and/or destination region / countries / Geo-Location where you can define action (allow/deny) against same based on your requirement. If you want to allow traffic from one specific region & block rest, then you can have two policies where one will allow traffic from one region and other policy you will have to configure below allowed one. This second policy will block traffic from unwanted region.

Below Palo Alto provided articles may help you with the configuration part. Also there is very good blog on this shared by @kiwi . Please check this to go through it. This will also help you.

Thank you very much.

I will have one more question. Which requires more resources DROP or DENY?

We do it in a Geo Location Deny rule (just what we have called it) and use the negate option to deny all traffic that isn't in the regions added from the outside to inside.  We also use regions on inside to outside traffic although you have to be careful as many of the content providers now have datacenters in various countries.  We are using Deny.
