In this Screen you will configure the GRE/PPTP specific connection params.
Note: Profiles using PPTP do not offer a Telco Options screen.
Enter the PPTP Partner IP Address. This specifies the address of the other end of the tunnel.
If you do not specify the PPTP Partner IP Address the gateway cannot initiate tunnels, i.e., act as a PPTP
Access Concentrator (PAC) for this profile. It can only accept tunnel requests as a PPTP Network Server
(PNS).
If you specify the PPTP Partner IP Address, and the address is in the same subnet as the Remote IP
Address you specified in the IP Profile Parameters, the Tunnel Via Gateway option becomes visible. You
can enter the address by which the gateway partner is reached.
If you do not specify the PPTP Partner IP Address, the router will use the default gateway to reach the
partner and the Tunnel Via Gateway field is hidden. If the partner should be reached via an alternate port
(i.e. the LAN instead of the WAN), the Tunnel Via Gateway field allows this path to be resolved.
You can specify a Data Compression algorithm, either None or Standard LZS, for the PPTP connection.
Note: When the Authentication protocol is MS-CHAP, compression is set to None, and the Data
Compression option is hidden.
From the pop-up menu select an Authentication protocol for the PPP connection. Options are PAP, CHAP, or
MS-CHAP. The default is PAP. The authentication protocol must be the same on both ends of the tunnel.
When the authentication protocol is MS-CHAP, you can specify a Data Encryption algorithm for the PPTP
connection. Available options are MPPE and None (the default). For other authentication protocols, this
option is hidden. When MPPE is negotiated, the WAN Event History reports that it is negotiated as a CCP
(compression) type. This is because the MPPE protocol uses a compression engine, even though it is not
itself a compression protocol.
You can specify a Send Host Name which is used with Send Secret for authenticating with a remote PNS
when the profile is used for initiating a tunnel connection.
You must specify a Send Secret (the CHAP term for password), used for authenticating the tunnel when
