Use different device name with FreeBSD

[Muenz, Michael]

Hi list

I'm want to build a OCServ plugin for OPNsense Firewall based on FreeBSD.
In the config there's an option "device" to set the name of the tun device.

It seems to work fine on Linux but it doesn't work for FreeBSD.
Whenever I connect with a client the device is called tunX+1.

Sadly this does interfere with the logic of OPNsense to assign 
interfaces via UI.

Do you see any chances to port this feature also to FreeBSD?

Thanks,
Michael
