The following example demonstrates uses of the IsPortAllowed function.

' Declare variables
Dim Allowed, Restricted

Allowed = FALSE
Restricted = TRUE
' Create the firewall manager object.
Dim fwMgr
Set fwMgr = CreateObject("HNetCfg.FwMgr")

' First a reminder on the various arguments:
' IsPortAllowed( imagefilename, ipversion, portnumber, localaddress, protocol, allowed, restricted)
