Hello! On which port are connected 2 modems who
communicate using PPP protocol ? One of them is waiting
(host), but the other is dialing (client). I will install
on the host computer with waiting modem software Firewall -
for example Sygate. I will create a rule for allowing of
TCP port which is used from the 2 computers for
communication. But I don't know PPP protocol which port
uses so that I can create a rule in Firewall for allowing
of this port.
