Load Balance Issues

[AdamB]

PM sent, very odd though as it didn't show up in my sent folder. Let me know if you didn't get it.

Spent some time wiresharking this traffic and all seems well. Traffic is most definitely going over the 96.238.145.x interface. Traceroutes still come back as using 71.176.110.x. Atleast its working. All the help is great appreciated!

Thanks for the wrap-up Adam.

Weird.
I took a look at your server.
It is indeed working correctly now.

traceroute does indeed make it look like its using the 71.176.110.x interface for "traceroute 66.133.115.128"
however, tcpdump shows that traceroute sends a UDP packet with a TTL of 1 on the correct interface, and indeed the response comes from 71.176.110.1 that the TTL has expired.
My guess is that you are using the same ISP for all of your links? Maybe the other links are just aliases for 71.176.110.1 so that each link has a separate subnet so you can balance them. Either that or the other gateways just route through 71.176.110.1 with decrementing the TTL.
Either way you can verify its using the correct interface for the traceroute with:

tcpdump -i eth2 -n "host 66.133.115.128 or icmp"
then in another window:
traceroute 66.133.115.128

I think in your case traceroute just isn't going to be a useful tool, because its going to respond the same for all your links.
