hello guys,

I got two firewalls which run hot standby, the servers connect to the access switch and the access switch connect to the firewall, both the gateway configured on the firewall. I found that I cannot ping some of the servers,

as the topology below shows, server 1 can ping server 3, but cannot ping server 2 and server 4. On the contrary, server 2 can ping the server 4 but cannot ping the server 1 and server 3.

OK.
then, please check if the active gateway ip address for server 1 and server 3 are on the same firewall while active gateway address for server 2 and server 4 are on another firewall,
if yes, please check if you have configured hrp mirror session enable, because when this command not configured, and the gateway for the different networkes are on the different firewalls, in which situation the forward and return packet paths maybe inconsistent
