Is it possible to enable port forwarding of the SCTP protocol when the network adapter for the guest os is set to "NAT"? It seems both the GUI and command line tool VBoxManage (--natpf1) are limited to ports belonging to either the tcp or udp protocol. For example:
VBoxManage [<general option>] <command>
modifyvm <uuid|vmname>
[--natpf<1-N> [<rulename>],tcp|udp,[<hostip>],<hostport>,[<guestip>],<guestport>]
If I set the network adapter to "Bridged Adapter" this is a non-issue since the guest os would be running as a stand-alone entity, however this requires two ip addresses (one for home os, another for guest os). I routinely connect to different customer networks, where allocating a 2nd ip is at times difficult not to mention the cumbersome updates I'm having to manage within my software since I cannot utilize the default ip from NAT (10.0.2.15).
Any advice would be greatly appreciated. thank you.
