Hey people,

my Linux box got rooted from a BIND exploit. It's very upsetting and frustrating on numerous levels - but I have a sane solution. I happen to have an older box running FreeBSD 4.0 that's been a simple NFS/SMB file server. It already has 2 NICs installed, so I want to make it a firewall/router.

I really don't know FreeBSD, but can get around ok, and understand general unix pretty well.

This box will need to do the following:

IP filtering
NAT
DHCP
DNS
and misc. portfw for httpd etc.

Obviously my first priority is IPfiltering/NAT. Where can I find some quick and easy docs to set this up. I have used ipchains for a long time and I understand filtering basics, just need syntax really.

Hope that gets me through this.

Let me know if it doesn't. Setting up the firewall and Internet connection sharing (using NAT) is a snap on FreeBSD.

I suggest ipf over ipfw. Especially you are running 4.0 (too many exploits), not the latest 4.3.
