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?
Nope. Get yourself one of those N100 things from topton. They are cheap and work well with proxmox/opnsense.
And waaaaaaay more powerful.
