About PPTP Tunnels

To set up a PPTP tunnel, you create a Connection Proﬁle including the IP address and other relevant information for the remote PPTP partner. You use the same procedure to initiate a PPTP tunnel that terminates at a remote PPTP server or to terminate a tunnel initiated by a remote PPTP client.

PPTP configuration

To set up the router as a PPTP Network Server (PNS) capable of answering PPTP tunnel requests you must also conﬁgure the VPN Default Answer Proﬁle. See “VPN Default Answer Proﬁle” on page 10-85for more information.

PPTP is a Datalink Encapsulation option in Connection Proﬁles. It is not an option in device or link conﬁguration screens, as PPTP is not a native encapsulation. Consequently, the Easy Setup Proﬁle does not offer PPTP datalink encapsulation.

Note: The Netopia R910 Router has access to Connection Proﬁles for tunnelling purposes. If the PPP dialup kit is not installed, you cannot use PPP as a datalink encapsulation, and you will have access only to ATMP and PPTP. If the kit is installed you also have access to PPP.

Channel 4 (and higher) events, such as connections and disconnections, reported in the WAN Event Histories are VPN tunnel events.

To deﬁne a PPTP tunnel, navigate to the Add Connection Proﬁle menu from the Main Menu.

However, when the address server has been conﬁgured, and the clients involved have no prior address serving interactions, the Netopia R910 will generally serve the ﬁrst unused address from the ﬁrst address pool with an available address.
