Shorewall firewall/router on FC5 not adding default route at boot
 

Hello,
I'm hoping someone may have an idea about this situation. I have a server running Fedora Core 5, Kernel 2.6.16 that functions as a router and firewall running shorewall. It has an external static IP address on one network interface, and an internal IP as the gateway on another network interface. The problem we're having is that whenever the server is rebooted, the default route is not added to the routing table. Once that is added manually via the route command, everything works as expected.

ifconfig -a shows (ext. ip's altered):

Displaying the routing table shows:

255.255.255.255 * 255.255.255.255 UH 0 0 0 eth1
111.222.333.92 * 255.255.255.252 U 0 0 0 eth0
10.10.0.0 * 255.255.255.0 U 0 0 0 eth1
192.168.0.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth1
default 111.222.333.93 0.0.0.0 UG 0 0 0 eth0

"111.222.333.93" is the IP address of the dsl modem that connects to the external interface of the router and is also static.

We are using Shorewall ver. 3.0.6.

Please let me know if I can provide more information. Any ideas will be greatly appreciated.

Thanks!
