Hi, this is a one of the strangest issue I've ever had. I have two offices that are connected over S2S vpn using two Fortigate. The VPN tunnels is up and stayed up. I can GUI into Fortigate on both sites. However, when I SSH into a switch that is sitting behind the FW, it disconnects me if I don't type anything for 5-7s. At first, I though it was a settings on the Cisco switch. However, this also happens when I SSH into Fortigate FW. It seems like there is a setting on the Fortigate. Any suggestions?
Thanks.
Hi,
I'd suggest you to check SSH traffic once you generate SSH traffic to switch :
#diag sniffer packet any 'host x.x.x.x and port22' 6 none l
x.x.x.x is switch IP
