[pptp-server] ADSL line pptp client not connecting.

[User SHALE Stuart Hale]

If your adsl is using the Cisco 675, you want to make sure your cbos is
version 2.1 or higher, and then enter the following command in enable
mode:


set nat entry 10.0.0.2 777 216.160.92.4 777 47

The problem is that the cbos version 2.01 doesn't support GRE (type
47) packets in pptp, so the 47 protocol at the end is the important
part. The 216.160.92.4 is an example of whatever the isp assigned your
router. Hope that helps.
