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?

    Putting a second router behind the first one will effectively turn off any ability for you to host anything from the inside of your lab network to the internet. What another person said is the best way to do this.

    Get a router/firewall capable of VLANs. A switch would help too. This is going to be the best way to do any hosting and the cleanest setup.

    I get that you don’t want to disrupt the rest of the house. But you have to make some kind of concession here. Between what is possible and what is reasonable.

        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.

    If your ISP allows for multiple public IPs (many will allow up to 2) then you can connect a basic dumb switch to your modem and connect each router to the switch.

    They will both get their own public IP and have their own physically separated network.

    An alternative is to get a higher end router and a managed switch and use VLANs to virtually separate the networks.

    >> i believe the modem is just in bridge mode and the router currently in use

    If it’s a modem only, there is no bridge mode - it just functions as a modem and hands out just one IP address - and you want that to be to the router. The router then does the DHCP. This is what you can’t just stick a switch on the modem first. You are kind of stuck, limited by the family limitation and your hardware limitation. I think u/danielvlee’s suggestion would be the least impactful if you could do it.

    But I’d be willing to bet that whatever you do, the fam is going to blame every slowdown or issue on whatever you do. At my work, we put up some antennas for a project and the neighbor - a cable company’s satellite head end - started complaining to us whenever they had an issues - despite the fact that we did not transmit.
