I proposed extra package to be able to use IPV4 FASTTRACK with VPN protocols. wrote an example script, but it is resource-intensive..
Contacted MT support for proper implementation (kernel module or userspace application as extra package or bundled with ROS)
nobody cares… and first I got response saying “IMPOSSIBLE”.. well, you just need to take your blinders off, first.
If I were to request some other thing that you are interested to fix/implement; i would get alpha build in a week or so..
