Linksys router and FTP server

Recommended Posts

I can't complete the login sequence when trying to connect to the IIS ftp server. Any help would be great.

 

The server is behind a Linksys 1 port router. I am using a non-standard port for the FTP server (e.g. 2121). I have tried both forwarding and placing the server in the DMZ, same output. I am WS_FTP as the ftp client, here are the logs for both passive and non-passive connection attempts (my IP addr has been X'd out).

 

Passive transfer:

 

connecting to xxx.xxx.xxx.xxx:2121

Connected to xxx.xxx.xxx.xxx port 2121

220 mayer-2 Microsoft FTP Service (Version 5.0).

USER ips

PASS (hidden)

230 User ips logged in.

PWD

257 "/" is current directory.

SYST

215 Windows_NT version 5.0

PASV

Port 21 is not an option. My internet provider has that port blocked to residential users (for good reason).

 

For the record, my ISP knows of my activities, and has given me informal permission to set up this server.

The reason why I ask, is that a friend of mine was having the same issue, and for some reason I couldn't connect to his server when using a non-standard port. Once he switched back to 21, it was fine. I have hosted FTP servers in IIS on non-standard ports, and not had any problems. And he told me others could get to his server even though it was on port 17.

 

So, can you connect on the LAN to that server on 2121?

Yep, just tried it. The ftp server worked fine in passive mode before I put the router on. Non-passive never worked with the non-standard port.
