the router if he is implementing FTP on two systems that are both on the router's local network? I thought that he would only need to open these ports if he was trying to FTP to the Internet?
Maybe it's an IP address or firewall problem?
You have a point there. On first reading it I took it to be that the "pc on my desk" was a work PC and xxkhbxx was FTP'ing to/from outside the LAN. On re-reading that may be an invalid assumption (for "invalid assumption" read "careless reading" on my part!), and if FTP'ing purely on the LAN then the port-forwarding wouldn't be necessary.
Could be a firewall problem. But OTOH xxkhbxx said "i never had a problem before i got the router" implying whatever, if any, firewall etc software was in place beforehand did not impede FTP. The implication is then that the router introduced the problem. So could, of course, then still be an IP address.
xxkhbxx: can you give more info about your IP addresses on the PCs? For example, do your think they are picking up IP addresses, default gateway, DNS addresses, from the router OK?
