Outbound traffic (originating from the servers):

-- Create two pools: one with VLAN A's gateway address, and one with VLAN B's gateway address.

-- Create two "wildcard forwarding" virtual servers. Bind one 0.0.0.0 virtual server to VLAN A gateway pool A, the other 0.0.0.0 to VLAN B, gateway pool B.

The nice bit here is that the gateways for VLAN A and B could be an upstream firewall with access policies, etc. - whatever fits your environment.

So now you've got your major traffic flows covered and their paths enforced. Very handy!

Hope it helps.

You can't assign a normal pool to IP forwarding virtual servers. Should this gateway pool be assigned as the "Last Hop" pool?
