How do I set a white list on a port forward?

[m10653]

Hello nice people of the Pf Sense forums.  I am trying to port forward but only allow white listed ips though that port. Does any one know how do this or if it is even possible. Also anyone who knows how to have non white listed ports redirect to a outside wan adress(ip)

Create an alias including all the ips you want to allow, then set the port forwarding using that alias as source.
