Lenny Firewall/router/DHCP

Goodafternoon,

I am using the tutorial "NAT Gateway, Iptables, Port Forwarding, DNS And DHCP Setup - Ubuntu 8.10 Server" to setup a Lenny box as a firewall/router/DHCP, and, after performing the requested tasks I can:

1. Aquire an IP.
2. ISP provided DNS servers are being forwarded.
3. I can ping any address.
4. I can resolve any address via my browser, but no data is being downloaded. I constantly receive a "Waiting..." status.
5. I can connect to any of my FTP sites, but whenever I attempt an "ls" or "dir", I receive an error stating that it will not transmit data to <172.xxx.xxx.xxx>, my private IP, only to <64.XXX,XXX,XXX>, my public IP.

Any thoughts? The configs are entered exactly as they are detailed in the tutorial, with the exception of different names and local IP addresses.

Thank you,

 

Regarding FTP, did you try both active and passive transfers in your FTP client?

 

Hi Falko,

In passive mode, I would only receive a less descriptive message.

sg.

 

changing transfert to active mode has solved the problem for me
