Another nic card on the DHCP server/firewall/nat box would make it a cookbook approach. You did use NAT, right? Also, if files in /etc/sysconfig/network, /etc/hosts and /etc/sysconfig/network-scripts are set up right, you might not need to use the route add scripts to get the gateway to show up in the routing table. As for the rains, I don't believe it. The best scapegoat these days is sunspots. The sysctl command was new to me.
