These BSD machines (gcc300-gcc303) are virtual machines which
are running inside an internal network (192.168.66.X).

The physical server hosting the VMs is
The NetBSD VM is
The public IP ( machine forwards the TCP ports (e.g. 2400)
to the internal VMs.

This seems pretty standard to me, but if there are possible
improvements to the VM's configuration I'm happy to try them.
