[vpn-help] Change virtual adapter's network (MAC) address?

[Michael Ford]

We had someone tie the licensing of some software to the MAC address of the 
virtual adapter by accident rather than the MAC address of the NIC.  I 
believe this causes the software to not work unless connected through VPN 
when the adapter is enabled and active.  I was hoping there was a way to 
specify what MAC to use for the virtual adapter in case it ever changed, as 
it now seems highly likely.

The MAC address is unique to the instance of the Virtual adapter.
Adapter instance 1 would always use the same MAC address. Adapter
instance 2 would always use the same MAC address, etc ... I'm not sure
what your question is in reference to. If your using DHCP over IPSec,
the local adapter MAC isn't used. Its spoofed and uses a different MAC
value for each connection with 2.1.7. Its spoofed and uses a persistent
MAC value in 2.2.0 because the constantly changing value was causing
address pool exhaustion.

What problem are you trying to solve?
