        How can I punch holes through iptables to allow for an external
    pcAnywhere machine (dialup) to connect to an internal (private network)
    one? On our old server, it was done using ipportfw, but that has long
    since been dropped off the back dock and a new server put into place,
    which now uses iptables. I need both tcp as well as udp ports 5631 and
    5632 opened.

        So, the path for data will be:

      [ remote ] [ firewall ] [ internal ]
      [ pcAnywhere ] <--> [ internet ] <--> [ iptables ] <--> [ private ]
      [ user ] [ server ] [ network ]
