ISA550W: Does WAN Redundancy support session affinity?

Hi, we're currently using the ISA550W in WAN failover mode.

I'm wondering if we switch to the weighted dual-WAN mode, is session affinity is respected? That is, if we have a PC on the internal network using an external web site, will all subsequent connections use the same WAN interface, or will they possible be switching back and forth between different WAN interfaces depending on the load?

I don't see any mention of it in the docs, so I'm assuming that it is not supported.

Thanks,

Neil

In Weighted Dual-WAN mode, a connection from a PC should continue using the same WAN connection for the destination the original session was established to.  However, if the PC opens another session (i.e. a connection to a different site), then that session should use the best connection, which may mean that it uses the WAN2.
