What is the recommended router with usb-tether support? Only need usb port for tethering and ethernet port for LAN; wifi not a requirement. Plan is to get two of these to connect to two ipads and then feed an ethernet connection from each to an AR750S-ext that is configured with two ethernet wan ports.
Or use the existing AR750S and a new one for tethering and get a new Beryl for load-balancing the wan. How would vpn work over dual wan connections? Seems like I would need a separate vpn connection for each wan connection.
