Third option, then: Put a switch after the ISP's modem/router, and plug everything that you trust not to eat up your download bandwidth through that. Connect your own router (the right way around) to manage the few things that you know will waste your download-bandwidth &/or data-allowance. As I mentioned in a prior mail, if you have two routers with their LAN side of themselves connected together, you're going to strike problems if they both are running DHCP servers. The DHCP servers will fight with each other, and you'll end up with clients changing their IPs unexpectedly. > I am never certain how I handled address assignment on some of those > things, DHCP static or simply fixed.

If you fixed addresses using a DHCP server, then look at that DHCP server's configuration. It'll list who and what. And anything else (that's not on its list) with a fixed IP will have been configured on the individual devices, themselves. Once you go beyond about four devices in the same room, having to manually configure each device becomes a real pain. It's almost inevitable that you'll strike something that requires a network reassignment, and have to go through all the work that entails to get everything working again (rejigging network addresses, host files, firewalls, various servers, etc). I've faced that twice: Once with a client device that could only ever work on a 192.168.1.x network, because it was stupidly hardcoded that way. Then again with an ISP supplied modem/router that was set up to run with a 10.0.0.x network. (Fortunately, I could reconfigure the modem/router, but it's factory default was 10.0.0.x, and ISP fault-finding begins with a factory reset instead of actual diagnosis. Which requires reconfiguring a client PC to regain control of the modem/router, so the LAN could cooperate with the other stupidly hardcoded device.) DHCP is designed for these situations: Central control over address allocations. With an associated DNS server to answer all the name queries. Ultimately, far less mucking around. _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
