@victorhooi:
Hmm, that's fair enough - what's the best way of setting up VoIP traffic so it doesn't load balance, and other traffic so that it does?
If you have a local PBX, match traffic from the PBX and assign it to a single WAN gateway, or a failover group. Use a rule at the top of the list, remember that first match wins.
If you have local phones and a remote PBX, match traffic going to the PBX, do the same to it.
So long as you have the rules in the right order it will do what you want.
Oversimplified example:
SIP traffic, use failover group
everything else, use load balancing group
