I am currently trying to run an FTP server through my wireless router
which is running m0n0wall.

I can't seem to get the redirection from the radio to my machine with
the FTP server to work.

My ISP told me that all I need to do is add a rule redirecting port 21
to the internal IP of the system running the FTP server.

I have done that but it just will not work.

Can anyone help point me in the right direction?

Any help would be GREATLY appreciated.

Thanks,
Paul
