I currently have two internet connections coming into my main office. The primary connection is regular static IP cable service and the secondary is a dedicated MPLS Ethernet connection. The primary cable internet terminates at an ASA 5510 (192.168.0.5) and the secondary internet connection terminates at an ASA 5550 (192.168.0.7). Both reside on the 192.168.0.0/24 network and are connected to a 4500-e switch with a 6L-E supervisor. The 192.168.0.0/24 network uses an ISR 2851 (192.168.0.1) router as the default gateway providing connectivity to 3 other offices through private IP service.
For a few years now all I had in the way of internet service was the static IP cable service. I had a default route in the 2851 gateway router "ip route 0.0.0.0 0.0.0.0 192.168.0.5" and all hosts on the 192.168.0.0/24 network were able to access the internet. However now I've come across a situation where I have one specific server (192.168.0.100) that needs to exclusively use my new secondary MPLS internet connection. For the life of me I cannot figure out how to get this to work. I only have limited access to the network settings on this server and can only configure things like the IP/mask and default gateway. I've tried adding a second default route on the gateway router but that didn't work. Any help would be much appreciated as I think I'm in over my head on this one. Thanks a lot!
