I seem to have ended up arguing on the internet, which wasn't really my idea :-(. Right, let's go through this again. Internet--------Firewall------Server 1 | ----------Server 5 I'm working on the firewall, a linux box. The firewall has addresses 10.72.2.1, 10.72.3.1 and 10.69.2.3, which goes off to the internet. Server 1 has IP 10.72.2.3 and default gateway 10.72.2.1. Server 5 has IP 10.72.3.3 and default gateway 10.72.3.1. Server 1 can see server 5. Server 1 can see the internet. Server 5 can see server 1. Server 5 can see the internet.. There are absolutely no routing problems whatsoever: Look! Here they are pinging each other! [root@server5 ~]# ping 10.72.2.3 PING 10.72.2.3 (10.72.2.3) 56(84) bytes of data. 64 bytes from 10.72.2.3: icmp_seq=1 ttl=63 time=2.83 ms 64 bytes from 10.72.2.3: icmp_seq=2 ttl=63 time=1.14 ms 64 bytes from 10.72.2.3: icmp_seq=3 ttl=63 time=1.48 ms --- 10.72.2.3 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2002ms rtt min/avg/max/mdev = 1.144/1.818/2.830/0.729 ms [root@server5 ~]# traceroute 10.72.2.3 traceroute to 10.72.2.3 (10.72.2.3), 30 hops max, 40 byte packets 1 10.72.3.1 (10.72.3.1) 4.367 ms 1.212 ms 5.749 ms 2 10.72.2.3 (10.72.2.3) 5.196 ms 4.715 ms 5.163 ms [root@server5 ~]# The reason I'm on the netfilter list, is because I'm trying to use the firewall linux box as a firewall. Like I say, with my rule sets, connections don't work from one server to the other for http traffic.
