Hello selfhosted.
My router just burnt up and instead of buying a new one, I’m thinking of turning my own built NAS/home server into a router. Is this possible?
The server in question is a normal computer running debian, where I have a few disks in RAID and host some web services. The motherboard only has one RJ45 port, so my guess is that I have to at least get a network card that supports 2 ports. I’m no stranger to linux but physical networking is not my home field, though I’m very interested.
If someone could point me in the right direction, I would be more than happy.
Ah I see, did not think of that. A network card with two ports would be enough right? One for the modem, and the other for clients, which ideally could be a switch, for more ports. That’s possible right?
Yes, that will be enough. You can also use a single port on the NIC and the one on the motherboard if it can handle the ethernet speed you want.
This is my network setup on Proxmox:
vmbr0
is a bridge that has a single port going to the modem. The OPNSense VM’s first virtual interface is connected to this and configured as a WAN interface. Nothing else connects to this bridge as it is exposed to the internet.vmbr1
also has a single port that goes to the physical switch. OPNSense’s second interface connects to it as a LAN port, as well as every other VM and container running on the server.I see, very nice. That would reduce the cost quite a bit. Thank you
Yes, that’s possible
