Raspberry Pi Zero as a router (alien.top)

I do not know whether I should ask here. Even though I am still thinking about turning my not-used RPI Zero into a router. Now I have an old Archer C6 v2 with OpenWRT and sometimes happen router turns off after connecting the PC. I know it is possible to do it, but I wonder whether RPI would be able to hold the traffic better than the Archer. I should point out, that traffic means a Proxmox server with 2 Linux VMs and 4 PVEs, a television, and 4 Wi-Fi connections. I am thinking about configuring OPNsense on the RPI as well. Would it work or do you have better ideas?

might work, but not for a lot of throughput.

CPU is not powerful enough, especially if you also dealing with encryption
You have only 1 NIC on these, which you will need to share for external/internal with some vlan config or virtualization (already cuts bandwidth potential in half
a work around for #2 is to use a USB NIC, which will put you in a bad spot with issue #1 again.

Get an Intel NUC, or ChromeBox or something like that. Or you can even run it virtualized inside Proxmox on another machine in your homelab. This is what i do, and it sits with a bunch of LXC's on the same machine (haproxy, UnifiController, CloudflareTunnel). Basically, all my network contollers on the same machine neatly in separate containers. Powered by a super cheap Celeron G3950 and 8GB RAM. food for thought.

Yeah, I have one old server with a two-core Intel processor, so I was thinking about using it instead of the RPI, but IMO it is quite overkill…dunno what to use the remaining power for
