Hi everyone,
I'm stuck on trying to use an alias from a VM. Everything works from
its main ip address 10.0.0.53 but from an alias, in this case
172.16.20.1, I can't manage to make comms going out from it.

For example with "ping -I 172.16.20.1 <whatever-ip>" or openvpn binding
from it. There's no firewall active and there is no block from the
border firewall for that IP address. At this point I'm wondering if
that could work at all.

For the record the configuration of the VM is pretty much based on the
"Option 4" of the official OpenBSD guide at
https://www.openbsd.org/faq/faq16.html#VMMnet

any hing would be appreciated.
Thank you.
