Hello, I have an SSG550 with multiple zones. Basically here is the problem, I have my admin workstation in zone A and my Cisco switches (and users) in zone B. When I try to SSH (or telnet) to my Cisco switches I am successful and I see the traffic accepted in the firewall (via NSM) logs. I am able to login, but after about 10 seconds my connection is broken.
When I ran Wireshark it shows me that the device stops responding to my workstation and I begin retransmissions.
If I use SSH (or telnet) from a PC on the same subnet as the switch it work fine.
I thought it might have something to do with Security Screening options (like SYN flood protection) that I recently enabled, but even when I disable it, it still happens.
The policy rule for Zone A to Zone B is Any Any Permit.
Any thoughts?
