LocalMAC property holds MAC address for the
adapter. MAC address is used by Windows sockets to correctly route raw
network packets between network adapters (local adapters, and remote
adapter). MAC address must be unique on the network. Changing this
property does not really change MAC address of the adapter, it only
changes how wodVPN sees the adapter (unless you know what you're doing,
do not change this value).
Local MAC value is sent to remote wodVPN peer when you set
RedirectActive property to True, since remote side needs our MAC
to route packets to us.
