Start method will make wodVPN active, and will
start accepting possible connection from remote peer. If Port
argument is specified, wodVPN will bind to that UDP port. If Port
isn't specified (or is 0), wodVPN will assign new free port and will
return it as result of Start method call.
Once component starts, you can call
Connect method if you know
other peer's Hostname/IP, or you can call
Search method to locate
remote peer (based on his ID). You can also do nothing - if remote side
is the one that will connect to your local peer, then calling Start is
sufficient - it will just sit and wait for someone to connect.
