i would like to set up a switch off of the router, and then have one modem for my families stuff and my gaming pc, and another router for testing as well as hosting a website. is this feasible? i believe the modem is just in bridge mode and the router currently in use functions as dhcp, i was thinking i could also connect the other router off of the switch, but would the packets collide?
Ignore the below responses. This will work ONLY if your ISP allows for multiple public IPs to be issued out of the same modem/account. In my experience, many ISPs will allow for two public IPs.
If they only allow for one public IP then it will not work as only one router will have internet access.
