Can't figure this one out. I've set up FTP with a filezilla server on my windows 7 machine at home. If I'm within the local network and connect with the LAN 192.168.x.x IP address, it succeeds, but if I attempt to connect to the WAN ip with the port forwarded it fails.

I thought my ISP might be blocking port 21 so this is all done with a random port I chose (port 10622). The port is reported as open by www.yougotsignal.com/tools/open-ports.

Things I've tried on the windows 7 machine:

  • Disabling firewall at the domain, home and public levels
  • Added additional rules allowing port 10622 to ingoing and outgoing (just in case)
  • Checked all settings for "exclude this IP" related settings (there are none)

I have RDP working correctly remotely with the port forwarded, so I don't think it's an issue with my router (which is a dd-wrt flashed cisco router). I am also successfully forwarding another random port for torrents.

Any suggestions are appreciated, thanks!

The ftp server is set in Active or passive mode ? –  aleroot Dec 24 '11 at 11:10
    
Passive, although I've tried both. –  John Dec 24 '11 at 11:13
    
netstat -na, pls. And check port-forward rules with any smart TCP-listener –  Lazy Badger Dec 25 '11 at 4:35
