What I am trying to do is I have multiple small networks (5+) with 4 devices (connected wirelessly) on each and then assign an ip to each network by using either vpns or proxys. Vpns or proxies must be done at the router level. Now I've made 1 extra network by connecting an asus router into the back of my main internet router and then entering the vpn details into it. This has given me one extra network but I need more and buying 5+ routers is going to be a little expensive. Is there a wireless router that could do all this for me in 1 unit?
