Internal Gateway Tunnel Mode

L2 Linker

What are the implications of using Internal gateways in Tunnel mode? I have 3 Palos on-prem at my datacenters. I have 7 total locations connected via MPLS.  I am thinking about using the Internal Gateways in Tunnel mode to prevent cross talk within subnets and force all communications to go through the firewalls.  Thoughts?

Besides the additional traffic this may cause and additional CPU/Memory on the PAN, I dont see why you couldnt perform this. Sounds like you are trying to follow the Zero Trust model. I fully agree with this model, just make sure your PAN's are speced for the sessions and bandwidth.
