A number of weeks ago I had huge help from many of you configuring routing on a server with multiple Internet facing nics. Thanks for all of your help!!!! I am still having a routing issue that I am hoping someone can help me tweek. This server, besides acting as our gateway to the internet, is also our web and email server. The server has 4 nics. Two are connected to the internet and the other two route traffic to internal subnets. Our network topography in question looks like this: Internet - Gateway Server - 192.168.4 subnet - Internal Server - 192.168.6 subnet - Clients The problem that I am experiencing is that part of our internal network, the 192.168.6 subnet cannot view our website that is hosted on our Gateway server. Our Internal Server can access the site but the Clients simply time out looking for it. If I point the Client to the internal address of the Gateway Server I can pull up the site but if I use the URL the browser times out. If I turn off my ip rules I can then view the URL on my Clients but of course external routing falls apart. /etc/sysconfig/network-scripts/rule-eth2 from 173.11.51.45 table Cable /etc/sysconfig/network-scripts/rule-eth3 from 67.152.166.2 table T1 /etc/sysconfig/network-scripts/route-eth0 GATEWAY1=192.168.4.3 NETMASK1=255.255.255.0 ADDRESS1=192.168.6.0 GATEWAY0=192.168.4.2 NETMASK0=255.255.255.0 ADDRESS0=192.168.5.0 /etc/sysconfig/network-scripts/route-eth1 GATEWAY0=192.168.4.1 NETMASK0=255.255.255.0 ADDRESS0=192.168.4.0 /etc/sysconfig/network-scripts/route-eth2 173.11.51.44/30 dev eth2 proto kernel scope link src 173.11.51.45 table Cable 173.11.51.44/30 dev eth2 src 173.11.51.45 default via 173.11.51.46 table Cable default via 173.11.51.46 192.168.4.0/24 dev eth0 proto kernel scope link src 192.168.4.1 table Cable /etc/sysconfig/network-scripts/route-eth3 67.152.166.0/27 dev eth3 proto kernel scope link src 67.152.166.2 table T1 67.152.166.0/27 dev eth3 src 67.152.166.2 default via 67.152.166.1 table T1 192.168.4.0/24 dev eth0 proto kernel scope link src 192.168.4.1 table T1 # ip rule list 0: from all lookup 255 32764: from 67.152.166.2 lookup T1 32765: from 173.11.51.45 lookup Cable 32766: from all lookup main 32767: from all lookup default # ip route show 173.11.51.44/30 dev eth2 scope link src 173.11.51.45 67.152.166.0/27 dev eth3 proto kernel scope link src 67.152.166.2 192.168.6.0/24 via 192.168.4.3 dev eth0 192.168.5.0/24 via 192.168.4.2 dev eth0 192.168.4.0/24 dev eth0 proto kernel scope link src 192.168.4.1 192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.1 169.254.0.0/16 dev eth3 scope link default via 173.11.51.46 dev eth2 # ip route show table cable 173.11.51.44/30 dev eth2 proto kernel scope link src 173.11.51.45 192.168.4.0/24 dev eth0 proto kernel scope link src 192.168.4.1 default via 173.11.51.46 dev eth2 # ip route show tabel T1 67.152.166.0/27 dev eth3 proto kernel scope link src 67.152.166.2 192.168.4.0/24 dev eth0 proto kernel scope link src 192.168.4.1 default via 67.152.166.1 dev eth3 Any insight would be greatly appreciated! I have been pecking away at it and I just can't seem to get it right. Thanks - Doug -------------- next part -------------- An HTML attachment was scrubbed...
