I presume the original question is how to allow outbound PCanywhere. PCanywhere sets up a connection by first contacting the target machine using UDP with a random source port and a destination port of 5632. (For backwards compatibility, if 5632 doesn't work, it will attempt port 22). Once that has been established, it will then attempt an outbound connection to port 5631 via TCP. The problem is therefore how you can allow inbound UDP responses back through your firewall. With dumb packet filtering firewalls, this can be tough. If the question is how to allow inbound PCanywhere, the answer is that you cannot. Many users install PCanywhere on their PCs with no password protection. Hackers scan the Internet constantly for such machines, and if you are talking about a firewall behind which reside many users, your entire company will get hacked. --- Crispin Cowan <crispinat_private> wrote: > Louis Mattera wrote: > > > I am having a problem getting thru my firewall at work using > > pcanywhere 9.0. > > Good.
