Entering Passive Mode (Wrong IP)

[oldhouse]

I have a problem with some ftp users that try to fxp.

Main problem is explained by this line in logs:

227 Entering Passive Mode (10,8,0,62,5,228)

Ftp client takes this IP to make transfer, but this is a VPN ip, not pc real IP.
I need to know if there is a way to force ftp client, whatever it is, to use the pc real ip, maybe with an advanced configuration.

If anyone is so kind to post such a solution in a clear way, I would be thankful.

Edit your ioFTPD.ini, Host = 0.0.0.0 should be replaced by Host = your_external_ip

I can't do that, cause external ip is different from real pc ip, since it's behind nat, and nat ip is not reachable from external addresses, and that's why i have to use a vpn.
Weird thing is that it happens only on some users.

Try:
Bind = real pc ip

Mainly used for when behind a router, but may make a diff.

I tried that too, but then no one will be able to reach server :confused:

Host is not used at all when connections are established.
ie Host = 0.0.0.0 or Host = real pc ip doesn't matter until the ftp client sends a PASV command.
Only Bind = xyz is used to determine on which IP it listens for connections. And Bind = 0.0.0.0 should be kept as it is. You only need to change Host = xxxx to what IP you want PASV to return.

This error stops some users because other users forced their FTP client to send the PASV command to the *other* ftp server they are fxping to. Thats means only the other server needs to support pasv, and not yours.
If some users are behind a gateway, they need to enable PASV to be able to download, which will cause this error for them too.

Thx very much mouton.
It was my fault setting Host to the right ip, but leaving bind with ; in fron of it.
Now it works fine.
Thx again :)
