Need FTP Server Help

Right this is really starting to get on my nerves.

FTP server is set up ok, using port 5555.

Its visible and I can connect on my LAN no problems.

I have an actiontec router (supplied by UK Online).

I have forwarded port 20,5555 & 60000-62000 (for passive mode).

All ports are forwarded for both tcp and udp.

Firwall is set to basic (which according to the manual means only NAT).

I can't connect to the server using an FTP client or telnet over the internet.

Tech support at actiontec say its an "advanced" call and want $30.

Anyone got any idea?

does your ISP allow these ports to be seen on the internet ?

Yes, they block 80, 8080 and 3xxx (forget the exact port but its proxy server default).

21 is fine and 5555 is too.

Just to add something GRC shields up test sees the port (5555) as stealthed.

what ftp server software?

can you connect locally?

Cereberus (sp?) and yeah locally its all ok.
