The other main problem of the gui tool is that it does not provide some required options, e.g. I want to open a port (say 2049, 137, 139) ONLY to my lan, but the gui tool does have place to enter "source", "destination", etc. It only provides port number and tcp/udp selection. How to do it with source/destination? Thanks. Hongwei
