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.
