ESXI Server & Palo Alto: The Inside Hosts that's on the same port Group as Palo Alto (inside interface) cant ping the Palo Alto inside Interface.

[ETate]

I have a ESXI Server with firewall (Inside, DMZ and Outside) zones

Palo Alto has a security rule to allow interzone traffic from inside to outside

Palo Alto has NAT configured for Outside Interface

When I try to ping from host to host on in the same port group...all is good.

When I try to ping from host to the Inside Firewall Interface, the ping times out..."Destination Unreachable.

Host---->Vnic------->Port Group-------->Vswitch....

Do you have an interface management profile assigned to the interface allowing ping? By default, the firewall's interface won't respond to ICMP traffic even if it's allowed via security policy.
