To start, I'm not much of a networking guy and am just learning the Sonicwall stuff. I have a client with a TZ 215 that was setup by another consulting firm (no longer on good terms).
The issue is that you cannot SSH out from the LAN to a WAN IP. I've checked the firewall rules and all LAN -> WAN traffic is allowed (any source/dest, any service, any protocol). The odd thing is that on occasion the log will show an Intrusion Prevention alert (see attached) from the IP we're trying to SSH to. Sometimes this alert is right after an SSH connection attempt sometimes 10+ minutes later.
Multiple computers on the LAN and multiple SSH destinations have been tested with no luck.
Any ideas or things I can look at?
