I'm running Win2K with ADSL (256Kbps). This is the Interface List:
C:\WINNT>route print
===========================================================================
Interface List
0x1 ........................... MS TCP Loopback interface
0x2 ...00 90 d0 14 eb c4 ...... Alcatel SpeedTouch USB RFC1483 ADSL Miniport
0x3 ...08 00 58 00 00 01 ...... DKW Heavy Industries VPN Adapter.
0x4000005 ...00 53 45 00 00 00 ...... WAN (PPP/SLIP) Interface
===========================================================================

If it is a configuration issue, shouldn't the tunnel not work at all? It is
strange that it works fine for a few minutes, and then hangs. I tested
whether it was because of high throughput rates as Jan Olderdissen
mentioned, but even without transferring anything over the tunnel, it stops
working after a few minutes.

Kind regards,
