I'm wondering if there is a way to connect two routers to one modem and have them being on two separate networks. I want to do this because I have my gaming computer and my families computers on the first network but I want to port forward on a server computer I recently purchased but I want to make sure that if the server is compromised that there will be no way to access the other network. I've heard of DMZ's but I already have a separate router I could use. If I can't setup two separate networks would a DMZ be just as secure or even more secure? My ISP is Spectrum and the two routers are both Netgear.
