5 Click the Tunnel Link Parameters tab.
The Tunnel Link Parameters screen appears.
6 Configure the Tunnel Link Parameters according to the following table.
Table 221 PPTP Tunnel Summary attributes
Attribute Description
Interface Displays the name used to identify this tunnel.
IP Address You can select RemoteAssigned to specify that the IP address for this PPTP tunnel is
assigned by the remote device automatically.
During tunnel establishment, this end of the tunnel requests an IP address. The PPTP server
component on the remote end of the tunnel provides one either from its local pool or from a
DHCP server running in that site. If you want Business Communications Manager to provide
an IP address from its local pool, you must configure the
Static IP Address Pool parameter in
Dial Up resources. For information about configuring this parameter, refer to “Configuring the
dial up global parameters” on page 689 .
You can also use a static IP address, but this requires coordinating this address on both ends
of the tunnel. Nortel Networks recommends that you use the
RemoteAssigned option
whenever possible.
Description Allows you to enter a brief description of the PPTP tunnel.
Interface Status Displays the current status of the interface used by the PPTP tunnel. The status can be
Disabled or Enabled.
You can change the status of the interface by selecting Disable or Enable .
Connection Status Displays the current connection status of the PPTP tunnel. The status can be Connected or
Disconnected.
You can change the status of the PPTP tunnel by selecting Connect or Disconnect .
When the Interface Status is Enabled, the PPTP tunnel is normally in the Connect state or in
the Disconnect state. You can change it to Connect state to connect the tunnel manually and
to Disconnect state to disconnect the tunnel manually - irrespective of the Tunnel Link
attributes.
Note : You cannot Disable the tunnel when the status is UP. To Disable the tunnel, you must:
1. Stop all traffic through the tunnel.
2. Change the Connection Status to Disconnect.
3. Change the Interface Status to Disabled.
Table 222 PPTP Tunnel Link parameters
Attribute Description
Remote PPTP
Server - Primary Allows you to specify the IP address of the primary PPTP server to which this tunnel connects.
Enter the IP address in the dotted format.
A DNS name of the PPTP server can be specified for this attribute. However, it takes longer to
establish a PPTP tunnel since a DNS resolution must happen first. In branch configurations,
the actual DNS server may reside in another location which could cause the DNS resolution to
take even more time. Therefore, it is recommended that IP addresses in dotted decimal format
be specified for Primary PPTP Server and the Secondary PPTP Server, if it exists.
Remote PPTP
Server - Secondary Allows you to specify the IP address of the PPTP server to which this tunnel connects when
the primary server is not available.
Enter the IP address in the dotted format.
