[cobalt-security] RaQ550 Iptables firewall

["Dave @ The Hostworks" <dave@xxxxxxxxxxxxxxxx>]

I know this may have been discussed before, but there was never a clear
answer.

Basicly what I need to do is allow ALL traffic on eth1 (internal network)
Deny all traffic on eth0 (external, public)
Allow required services (22,23,25,53,80,81,110,imap,3306 and so on.)

Now I am aware that the RaQ550 uses iptables for  ip accounting, and any
changes to that file will just be overwriten by the system..

So my question is this, for anyone that has done this, whats your setup, and
could you also provide me with your basic iptable rules?

Thanks a bunch
