At the moment we are looking for a 10/100 dual (or multi)-wan router with VPN capability that would load-balance VPN traffic and would provide redundancy if one line were to fail temporarily. It would also require NAT. Firewall and Wifi are not essential. It would also allow us to configure some traffic to always use one of two existing gateways.
Can someone tell us whether such a dual (or multi) wan router exists first of all? And does anyone know of a good place to start to beef up our knowledge on the subject?
