[SOLVED] FTP replies with external IP address from within LAN

Annielover · 08-04-2011, 02:39 AM

Hi,

I've set up an ftp-server using Vsftpd and it's working perfect outside the LAN.
The server replies with it's external IP address, so for example 213,49,117,194,11,224.
But when I connect locally from within the LAN, it ALSO returns an external IP address. But, obviously, I cannot transfer files then.
How could I fix it?
I use Ubuntu Server 10.04 LTS

Code:

#passive settings
pasv_enable=YES
pasv_max_port=3100
pasv_min_port=3000
pasv_address=ftpronse.dyndns.org
pasv_addr_resolve=YES
port_enable=YES

I know, I use a domain name as passive address, but when I comment this option, the server returs an unroutable IP address...

Thanks in advance!

You can set an alias in the /etc/hosts with the local address. It should work.

perhaps this is an overkill of a solution (as a matter of fact, it's a hack).

Did you try setting the IP address of the network interface for this traffic with iptables? perhaps a MASQUERADE or SNAT on POSTROUTING?

That worked for me, thanks!
