Odd IPTables Problem

Looking for suggestions on this one, it's quite odd.  I have a small colocated network with 3 boxes.  1 Firewall with a public/private interface doing NAT, and 2 servers behind.  I've had to reset my IPTABLES rules already twice because I lose access to the box doing the firewall/NAT.  It works fine for a bit, then dies, denying me remote access to anything on the firewall, yet at the same time the NAT still works and I can reach services that I've mapped on the private network, just cannot reach the firewall box or any services on it.  ARRGH!  Any suggestions are appreicated.

It would be a help to know what Linux distro and version are in use. It would also help to be able to see what IPtables rules you are using to set up the firewall.

Linux is Fedora Core 1, all patches applied.  Firewall rules I can't get to right now as I cannot access the box, esentially I have.

Allow Established, Related
Allow lo
Allow Port 10000 (webmin)
Allow Port 22
Deny

And on the NAT I have mappings through to the private network and Masq outbound for all internal network addresses.

I think I'll need to see the actual rules.
