I'm working with a SA520W Security Appliance and having difficulty connecting to a SSH server on the LAN.
I have create an inbound (WAN zone to LAN zone) firewall rule for Service SSH:TCP, Enable Port Forwarding to 22 to the destination LAN IP, but have been unable to connect from any external IP address to the internal SSH server via XShell or PuTTY software. Within the LAN, I'm able to connect successfully.
Correct; within the LAN I'm able to SSH using the server's internal IP address (192.168.xxx.xxx) or Host Name. Just unable to SSH into the server from a remote location. Also, before implementing the SA520W, we had a RSV4000, which SSH passed through without issue from any remote location.
I assume you are using the built-in service on the device. Try setting up a custom service and changing your forwarding rule to use your custom service. If this does not work, call into the SBSC and open a case so we can document the issue. 1.866.606.1866. You may ask for me, Jason McCord, I will be happy to work with you if I am available.
