I have a bit of a problem with my new ISP's setup. They gave me a router (not a modem) that I HAVE to use. It's so locked down that I can't disable the router or the DHCP on it because it's needed for other services like tv and phone (don't know too much about Fios).
My problem is that I already had a network setup with my own router that I need to use since it has built in VPN and other settings I have. Also my Windows 2003 server acts as my DHCP server originally. My new ISP router is on 192.168.1.1 and my original is on 192.168.0.1. How can I feed the internet connection from the ISP's router to my original router so my existing network all still works?
