Hi everyone :)

It's time to switch and give my home network a proper minimal hardware upgrade. Right now everything is managed by my ISP's AIO firewall/router combo. Which works okayish, but I'm already doing some firewall/dns/VPN stuff on my minimal spare laptop server to bypass most of my ISP's restrictions. So it's time to get a little bit "crazy" !

While I do have some "power user" knowledge regarding Linux/server/selfhosted services/networking, I'm a bit clueless hardware wise, specially regarding my ISP's 2.5G ethernet port.

I do have a 5giga connection from my Internet provider (Obtic fiber) which is divided into 4 ethernet ports (Eth1 2.5G, Eth2 1G, Eth3 1G, Eth4 0,500G or something in that range). And right now the Eth1 port is connected through an old 1G switch.

1. To take full advantage of my ISP's 2.5G ethernet port do I need a router AND a switch capable of 2.5G througput ? Or only the router and the switch is going to divid it accordingly between all connected de
