Hi All,
I'm tearing my hair out (what's left of it!) trying to set up a VPN thru a Vigor 2600 router (Firmware Version : v2.5.6_UK ).

I've done the usual stuff:

1. Unchecked the boxes in Remote Access Setup Control

2. Forwarded port 1723 to my server's Internet facing NIC.

I get 'error 721 The remote computer is not responding' when verifying username and password when trying to connect from client.

The SBS 2003 event log entry shows a connection was established but not completed and suggests gre 47 error.

Any ideas please?

Sid
