I'm trying to get Devil Linux (a live cd-based firewall distro) to work, and I just can't seem to get it right. It boots fine, I run the setup, configure both cards, DHCP client on one, DHCP server on the other, and chose "basic two card firewall". Reboot.
When it comes back up I can use Lynx to browse on the box, so I know it's on the network. I boot up the Windows 2000 box behind the firewall, and it gets the appropriate IP (10.0.0.20), but when I try to get to the Internet either through a browser, or by pinging, I get "unknown host" errors.
I cleared the tables (iptables -X; iptables -F, etc.), and then set the default on all tables to ACCEPT (iptables -P INPUT ACCEPT; iptables -P OUPUT ACCEPT; iptables -P FORWARD ACCEPT), so I should have a wide-open firewall. It still doesn't work.
I figure I must need to tell iptables which iface to use, but I can't figure out how. Also, do I need to restart iptables, or does a rule automatically get implemented once it's made?
