Port Mapping is used when a computer with a private address needs to be accessed remotely.
Access to the computer is allowed only on the ports that are specifically configured.
Adding and Deleting Port Mapping
The IP Address of the computer that is being mapped to must be a static private address.

Commands to let PPTP (Microsoft VPN) pass through the FlowPoint router
Only a single PPTP client can function from behind NAT. Multiple clients are not supported.
system addserver IPAddress tcp 1723
system addserver IPAddress 47 0
If you get a failed to add server error, it may be due to the ports already
being configured for a different IP address. The old config can be removed by:
system delserver IPAddress tcp 1723
system delserver IPAddress 47 0
