Thanks unicorn, but I have a couple of questions on what you talk about on D Link routers...
I have a DI-704 and the setup is not very clear in the manual as you state...
I have set mine to open port 5000, for example, to my server machine, 192.168.xxx.xxx. But you talk of setting to port 21 on the internal 192 machine and I don't follow...
Are you talking on the virtual server page ? This only runs the requests from whatever port, to your internal machine (192....), how do you make it think that port 50000 is 21 on your internal 192.... machine ?
I have read and re-read the manual, and see no reference on how to make the router think that port 5000 for example, is port 21 ?.....
I don't have alot of trouble with people hooking up the way I have set up the routers I have, BUT, if I use port 21 on my FTP server, and OPEN port 21 on my router ONLY, then almost everyone can access easily....
BUT, if I set up my FTP server on another port, say 5000, then SOME have trouble connecting, even though I have port 5000 open on the router AND port 4999 open as well....
It seems to be the same for all 3 of my routers, no matter how I hook them up unless I use DMZ, and then you in effect, have no NAT protection at all....
I am not trying to be smart a** about this, I just don't understand the internal port 21 you speek of, unless you mean an FTP program, and you have to set those up for the port you are allowing access threw...
What am I missing here ?
Thanks again for your help and ideas
SeeYa
