Can't get server to work since going wireless

Hi all,

I went wireless back in December 2005 and since then have not been able to use my private FTP server (on places like GFF). I use No-IP DUC running in the systray, I have GuildFTP open to allow the connections and I am using a Linksys router.

However, no matter what I do, I cannot get anyone to log in. This is HIGHLY annoying and I can't see how I can fix it. The No-IP support didn't help at all, and I still can't get anything to work.

I know NOTHING about IP, forts, forwarding and all that so would appreciate a layman's answer if anyone can help, please. It's driving me up the mofo'ing wall.

Thanks guys.

Jam it back in, in the dark.
