[vbox-dev] Static route or default gateway for NAT

Dear Development Group

I am trying to demonstrate routing in a virtualised network created using VirtualBox with a FreeBSD server acting as router between 2 virtual networks. One network is set as NAT Network to allow access to outside world. However, although packets can be directed from the router to the NAT router for outward delivery, the NAT router does not know how to deliver the incoming packets for the "hidden" subnet.

I wonder if anyone has modified the NAT network to allow simple static routes or default gateway to support this cnfiguration.

I do not know the interest for this functionality and whether the work is justified for the use that would be made.
