Q:
I want to implement a load balancing solution with BorderManager. There are 2 internet links, one for the proxy/http traffic and the other for the VPN connections. How would this work?
A:
What is between the NBM server and the Internet connections? Hardware routers? Does one of them by chance have at least some sort of basic http proxy? If so, call that one Router A. Then you could configure Router B (the router on the link that you want VPN traffic to go through) as the default route on the NBM server. Then configure Router A as a parent cache in NWAdmin (CERN would be fine for this). That way all Web traffic is going through Router A and everything else including VPN) is going through Router B.
Another option, if there's no Web proxy on the routers - enable NAT on Router B and set up a static NAT for the VPN service. Then all VPN traffic will go through Router B no matter what the default gateway is on the NBM server. This will work with NBM 3.8 only.
If there are no routers between NBM and the Internet links (that is, if you want both circuits plugged directly into the NBM server), then you're probably not going to be able to do this.
