Hi @All,
I want to share an issue to see if anyone has ever encountered the same.
When I upgraded my r77.30 gateway to r80.20 (with CPUSE), server packets return do not cross my firewall.
Here is a diagram which details the issue:
Client ------ eth1-GW-eth2 ------ Server
when I do a fw monitor on my gateway GW, I see icmp request from Client that enter on eth1 and go out eth2. But no icmp reply on eth2.
When I do a tcpdump on my gateway GW I see icmp request from Client that on eth1 and eth2. AND i see icmp reply on eth2.
When i do "fw ctl zdebug drop | grep IP_Client or IP_Server I don't see any drop packet.
(Same things for tcp packets)
Thanks for your lights.
Regards
