Greetings, I am having a hard time figuring out how to bridge vport(4) and tap(4) interfaces.
Previously, I had set up vmm with bridge(4) and vether(4), and all was
working well. However, I recently heard that veb(4) has better
performance, so I tried to replace my bridge0 and vether0 with veb0 and
vport0 respectively, but now it's failing.
This I think is due how "to veb takes over the operation of the interfaces
that are added as ports" but I'm not sure how to fix it.
When I try to use one of the VM IPs (like 104.167.241.51) it is unable to
reach the IP assigned to vport0 (104.167.241.49) even though ip4 packet
forwarding has been enabled.
Here are the configurations and networking output:
$ cat /etc/hostname.veb0
add vport0
$ cat /etc/hostname.vport0
inet 104.167.241.49 0xfffffff8
inet6 2602:fccf:4::1 48
$ cat /etc/vm.conf
