OK. So what am I looking for here? The upstream gateway doesn't have anywhere near the options that the ER3 does. It has a basic setup like this:
and it shows the ER3 router as one of it's 'connected devices'. But beyond that it doesn't have many options...some stuff under andvanced like port forwarding, port triggering, dmz, device discovery etc. It also has a 'bridge mode' but reading on that it disables all the ethernet ports on the cable router which doesn't help me. Is there a way to tackle this from the ER3 side since that has a much more full featured set of options?
thanks
