This is good to hear.  Now I know it can be done this way, although I 
still prefer OpenVPN for it's security and ability to let you do other 
things such as AMI or whatever.

It is kind of hard to portscan 5060 when it is not open.  I bet I could 
do a portscan on 5060 and of those hits try username 100 password 100 
all the way up to 9999 and eventually get some toll fraud access in a 
day's time.

Thanks,
Steve
