Re: Modem GUI w/ Router - ISO Definitive Answer

Yep. That's true. But it will still cause trouble if you try to overlap it's 192.168.0.x subnet regardless of what your router gets on it's WAN interface. That's how you get to the admin interface, and if your router thinks it's a LAN address it won't pass it to the modem.

Double-NAT isn't much of a problem on this modem since it passes everything through, sort of like a DMZ situation.

In any event, glad to hear you figured it out.

No I think I got it right the the first time. The issue is mostly one of what IP address the modem is handing out to the router's WAN port, and how your router handles having the same address segment(s) on each interface.
But by default, the modem gives anything behind it a public IP address -- and this is a good thing since it avoids having to deal with double-NAT.
