What more details are you looking for? The TPI seems pretty clear?
request: ProE @7788 ---> firewall ---> server
reply: server @??? ---> firewall ---> Pro/E client
If you don't like the question marks, specify the reply port in the
DAEMON line of the license file on the server.
I don't think it is needed, because most companies use a Windows
firewall, and then you can simply specify that a certain program is
always allowed to pierce the firewall to the outside world. On Unix you
can usually specify that replies to requests are allowed through the
firewall, so there you don't need it either.
But I suppose it depends on the software you use, and your company
policy on firewalling.
