I am replacing a Linux based firewall with Sonic Wall TZ210. RWW was working with the old firwall, but will not work with the Sonic Wall. I went through the wizard in the Sonic wall for Web server which forwarded Ports 80 and 443 to the server. I then added Port 4125TCP as a service and added that to the Service Group created by the Wizard. When I attempt to connect externally, I get "Page Cannot Be Displayed". I looked at the config of port forwarding on the old firewall and 4125 and 443 were forwarded to the same internal IP I am using. Is it likely a problem with my config on the firewall, or do I need to make an adjustment on the server?
