Can't get into an FTP deployed with serv-u 6.4

[Starriol]

I need to configure an FTP server so a client can access some files on a server.

Whenever I try to connect, I get an error similar to this:

1) Verify that the destination IP address is correct.
2) Increase the connection timeout threshold under Global Settings | Connection.
3) Switch to the opposite data connection type (PASV or PORT) under Site Settings | Type tab.
4) Verify that the problem is not local by trying to connect to an alternate server.
5) If a server name was used, verify it resolves to the correct address.
6) If using a local server table for server name resolution, check to see that it doesn't resolve to an obsolete address.
7) Try pinging the address.
8) If you are using a router, verify the router is up and running (check by pinging it and then ping an address outside of the router).
9) Do a traceroute to the destination to verify all routers along the connection path are operational.
10) Verify that your subnet mask is setup properly.
11) Verify that your local software or hardware firewall is not blocking outbound connections originating from CuteFTP.
12) Verify that your anti-virus software is not at fault (try disabling it).

I've read that a problem with PASV servers is that they open several ports randomly in order to establish a connection, so that's why I can get to log in, but don't progress from there.

When connecting from the LAN, everything works perfectly

Any ideas on how to solve this? Which ports should I open? I have a Linksys BEFSR41 V3 router by the way.

If you think it'll be simpler with another FTP server, I'll change it, no problem.

Also, I tried several FTP clients and nothing. I even took the timeout to 2 minutes and nothing.

Thanks guys,

In Serv-U, you can specify which ports to use for PASV and what IP to use. Usually, you will want it to detect the public IP you are using. You also have to forward the PASV ports on your router. There is a section in the help of Serv-U that explains this.

Done it, redirected port 20 to the server's ip, configured the server to use UPNP on the router, the router to accept that. I configured the PASV ports to be in a strange range so it's safer and worked as a charm!

Thanks guys
