Harbor235,
We will be connecting a hardware loadbalancer to the ethernet port of the router. We want the load balancer to do the proxy arps. The load balancer is a powerlink 200 by Ecessa.

Question
Cisco 2600 T1 Router Configuration
A simple question I hope....
I am thinking of making some infrastructure changes here that will require us to modify the way the router handles IP traffic. Specifically, we have a next hop route line in the router config that forwards traffic for any of the IP's in the subnet to x.x.x.x (our Firewall). We want the router to JUST do ARP requests for the individual IP's that it is routing traffic for instead. So, I want to confirm if I remove the HIGHLIGHTED BOLD LINE below in the config that the router would behave in this fashion, or must I make other entries in the config?

If you remove the static route then the traffic will be routed to the default nexthop out Serial0/0.1, is that what you want? Default route is used if the route is not in the routing table.
You are describing proxy arp for IPs that are local to a router interface, it will not arp out on non ethernet interfaces, like your serial interfaces, they do not use ethernet.
