non-pasv ftp

I admin on a MUD, and require ftp access to upload code to the MUD. But for al ong time I haven't been able to. If I remove my router/firewall I'm able to access it just fine. But otherwise I can access but not start any sort of transfer. Basically what I'm looking for is the correct settings for the router and the ftp program to get it to work. I've tried setting up port forwarding with no success. I just upgraded the wetwear of my router and now I see port triggering, which it says is for ftp. (It could have been there before and i just didn't notice it) Would be glad for any sort of help.
