Comment on choosing a NIC for OPNsense

• lightnegative@lemmy.world ⁨1⁩ ⁨month⁩ ago

  My proxmox “cluster” is a bunch of old laptops with a single consumer grade NIC in each. I wanted to isolate the VM network from my main home network (have it on a different range) while still allowing all the VM’s to transparently talk to each other regardless of which physical host they happen to be on.

  Could I have achieved this with normal vlans? I wanted an overlay network on the VM side but they still need to use my main home network to get internet and I only have a single physical interface.

  The OPNsense VM routes between the two networks (the virtual vxlan within Proxmox + my physical home network)

    Vxlan is way overkill

    It would be way more performant to use 802.1q vlan tags

      Wouldn’t all my consumer grade switches need to support vlan tagging? I’m pretty sure a bunch of them dont
