vpn thru a load balancer

[billmx]

We have a sonicwall router and an ecessa load balancer that connects to ISP1 and ISP2. An outside user connects to our sonicwall vpn using the client software specifying ISP1 as the endpoint.

Can someone explain how the return traffic moves to the remote user ? Will it always route back thru ISP1 because that's where the vpn endpoint was established ? If ISP2 has lots more bandwidth available, might the load balancer send the traffic down that path or is that not the way that VPN's can fundamentally work ?

The end goal is we are hoping to save the bandwidth on ISP1 for VPN traffic and let internal users do their thing on ISP2.

Thanks !

Need a little more information on the location of the load balancer, the IP addresses on the VPN appliance, default gateways, etc.

With information about the location of the devices, IPs, and gateways we could probably give you a fairly accurate answer.
