2: Enable PPTP:
Click on the VPN menu item (By clicking on the "Internet Settings" menu followed by the "VPN" menu item) and enter the PPTP/GRE server
IP address and user name and passwords in the appropriate boxes and click "Enable" and then "Save".
To check that the PPTP/GRE interface is up, click on the Status menu and in the PPTP/GRE section, the status should be shown as "UP".
NOTE – It may be necessary to add a static route. The Gateway IP address is the same as the PPTP/GRE server address. Enter the PPTP/GRE server IP address in the Gateway
IP address box.
Example:
If the PPTP/GRE server address is 203.44.251.100 and the IP address of the local PPTP/GRE interface is 10.1.3.42 (i.e. a 10.0.0.0
address) then in the static routes section, you would need to enter the following:
10.0.0.0 in the destination IP address box
255.0.0.0 in the IP subnet mask box
203.44.251.100 in the Gateway IP address box.
1 in the metric box.
Editing the PPTP/GRE credentials:
If you need to edit the PPTP/GRE credentials you need to disable the existing PPTP/GRE connection and then enter the new credentials
and re-enable the connection.
Disabling PPTP/GRE:
If you want to completely disconnect both the PPP and PPTP/GRE interface from the network then it is best to first disable the PPTP/GRE
interface simply by clicking "Disable" and hitting "Save" and then disabling the PPP connection by clicking "Disable" for the appropriate
profile number on the "Connection" configuration page.
However, if you want to leave the PPTP/GRE enabled for future use then just disable the PPP connection on the "Connection" configuration
page. The next time a PPP connection is enabled the PPTP/GRE interface will also come up.
Note: GRE TTL (Time to Live) limit is 255 on the period of transmissions.
