Comment on choosing a NIC for OPNsense
Why the MTU change?
Proxmox requires subtracting 50 from the MTU so it can store it’s vxlan information in the packet.
From the docs:
Because VXLAN encapsulation uses 50 bytes, the MTU needs to be 50 bytes lower than the outgoing physical interface.
It’s super annoying but I couldn’t see another way of having vms be able to talk to each other transparently regardless of which node they are on
Ah, ok, good to know, thanks
