PPPoE does not usually require any special configuration of the modem.
PPTP is used to set up virtual private networks (VPN) in unsecure TCP/IP environments. It sets up
two sessions.
1
The first one runs on TCP port 1723. It is used to start and manage the second one.
2
The second one uses Generic Routing Encapsulation (GRE, RFC 2890) to transfer information
between the computers.
PPTP is convenient and easy-to-use, but you have to make sure that firewalls support both PPTP
sessions.
