I have a network with two subnets. The primary network connected to the Sonicwall LAN port is 192.168.2.0 and the secondary subnet connected to the OPT port of the Sonicwall is 192.168.200.0. My print server is 192.168.2.160.
If I have the rule allowing ANY from OPT to LAN and ANY from LAN to OPT, the users on the 200 subnet print just fine. When I tighten the firewall, printing fails from the 200 subnet, with just garbage charactors printing. I have been unable to find any documentation to tell me exactly what ports to open, and web searches have given different answers. My rules allow the following ports to be open: 9100-9103, 515,631,1077, 4100,4200,4300, but I still have problems.
Any suggestions out there
