I am in need of turning on/off a specific port (i.e. License Manager port for Flex) across the VPN. 
This would allow
our people to be able to use a specific product here and not at the other site.  Then at a certain
time I could turn
the port back on and they could use it again.  Normally I would create a crontab or similar. Is
there a way
to do this.  The port is 5281 across VPN.
 
Thanks,

Travis
