I am looking for a way to isolate wireless traffic from my main LAN traffic and still force all traffic through a transparent Untangle machine. Has anybody done this without using double NAT? I would prefer to have some wireless clients included in the main LAN like using tagged vlans but I am open to any solution right now. I think the main problem is Untangle does not support tagged vlans. I was playing around with 2 RVS4000 routers. I tried super scoping the front door router so it would NAT the second network. The second router does not seem to handle the required sub netting.
