I have a 4 port linksys router. I am trying to serve an ftp site since I have 100KB of upload on my cable. When I forward ports like 99 or whatever I set my ftp to, lots of people have trouble listing the dirs when they log in. If I set the port to 21 and forward ports 20 and 21 it works. Any way of me getting other ports to work? I just do not want my isp scanning port 21 and bitching cuz I have an ftp running.
