Hi Team,
Has anyone created GRE tunnels to Zscaler or anyother third party from a Palo Alto firewall in Azure or GCP?
I tried and didn't work and bit of research seem to suggest that Palo Alto doesn't support GRE behind NAT ( Azure or GCP you can't assign public IP directly to the firewall interface and NAT is done by them)
