We handled this by creating three VSes - one with a profile tuned to LAN, one tuned to WAN, and one tuned to extreme-conditions WAN connections. The LAN and WAN profiles are pretty much vanilla LAN/WAN profiles in 9.4, and the remaining one is meant for high-latency connections.

 

 

From there we have two ways of determining how to stick the connection to a particular VS -- the first is GTM -- it assigns most everyone to either the WAN VS or the Extreme WAN VS based on topology lookup (overseas networks are sent EWAN-VS, everyone domestic gets WAN-VS). We then use an iRule on each VS (the same iRule applied to all VSes actually), that detects connections coming in with the "base" hostname and issues a quick redirect to either stick them to the VS they need, or redirect them to a new VS based on a source network check.

 

 

Does this make sense? If you need additional explanation, let me know.
