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?
i have a unmanaged switch currently. i wasnt going to connect the router to the router, but rather this: https://ibb.co/m6d8qV1
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.
