The PPTP/L2TP Configuration link displays a page where a new PPTP and L2TP connection can be configured, as well as PPTP and L2TP server settings can be adjusted. The page consists of 3 sub-pages.
The Connections page lists all existing connections are listed, characterized by their Connection Name, the Type of the connection (PPTP or L2TP), the Client/Server mode, the State of the connection and the Remote IP/Hostname (the IP address or the hostname of the connection peer). The state of the PPTP or L2TP Connections, except for the "Stopped" state, is created as a link that refers to the page where logout information about the connection status is displayed. Logs can be useful to determine problems on PPTP or L2TP connections failure.
Following functional buttons are available on the page:
Start is used to initiate the selected connection(s). If it is a client connection, then this button initiates a client activity of reaching the server. The Start option is applicable for multiple connections selected at the same time.
Stop button is used to stop the selected connection(s). Stopping the server connection will disconnect all connected clients and close the PPTP/L2TP tunnel. The Stop option is applicable for multiple connections selected at the same time.
Add leads to the PPTP/L2TP Connection Wizard where a new PPTP/L2TP connection can be created. Note: After creating a PPTP server connection, PPTP connections between devices placed on Quadro LAN and external devices will no longer be possible. The PPTP pass-through service for incoming and outgoing traffic will be automatically disallowed once a PPTP server connection is created.
Edit opens the Edit Entry where PPTP/L2TP Connection can be edited.
Delete removes selected PPTP/L2TP Connection(s) from the table.
Select all selects all records in the table.
Inverse selection inverses the current selection (if no records are selected, clicking on inverse selection will check all records).
The PPTP Server Configuration page is used to configure PPTP server settings and consists of the following components:
PPTP Subnet text fields are used to enter the IP address range for the PPTP server and clients within the PPTP tunnel. The value specified for the Subnet Mask is fixed to 24 to restrict the possible number of clients for the PPTP connection.
Note:
The first address specified in the PPTP Subnet will be assigned to the PPTP server, others will be assigned to the clients. The PPTP server subnet should be different from the L2TP server subnet, otherwise corresponding error message will appear.
The Authentication manipulation radio buttons are used to select the corresponding authentication protocol by which the client communicates with the server. The MSCHAPv2 selection enables the Encryption drop down list where the encryption method can be selected.
The L2TP Configuration page is used to configure the L2TP server settings and consists of the following components:
L2TP Subnet text fields are used to enter the IP address range for the L2TP server and clients within the L2TP tunnel. The value specified for the Subnet Mask is fixed to 24 to restrict the possible number of clients for the L2TP connection.
Note:
The first address specified in the L2TP Subnet will be assigned to the L2TP server, others will be assigned to the clients. The L2TP server subnet should be different from the PPTP server subnet, otherwise corresponding error message will appear.
