I have somewhat limited understanding about networking and I was wondering, that could I use my FreeBSD server as a router with a network switch, because the machine has only one Ethernet port. I would connect the FreeBSD router to the network switch and the network switch directly to the out-port which leads to the internet. I made picture about the layout of my network plan.
- Could I still have a router firewall to protect my network even if my router wouldn't be directly connected to the internet?
- Could my FreeBSD router block other machines to access internet?
- Would all packets (in going and out going) go through my router?
