I have a connection between two networks over vpn. In the Main office there is a sonicwall tz-170 connected to the remote office over vpn with a d-link dfl-200 firewall. It works fine over tcp/ip protocols like ping - no problem. So far so good, but I need netbios for mounting a network drive in the main office. I tried other connections between sonicwalls and it works fine. I tried to configure on the dfl-200 some rules with ports 135-139 and 445 open for incoming and outgoing traffic but it didnt work. I have poor experience with configuring a d-link firewall so my questions are now, is it possible to work over dfl-200 firewalls with netbios and when, are there specific parameters to set. I could not found any parameter to explicit enable netbios like in the sonicwall firewalls.
Thank you for your help
