Hi all,

I updated to 3.7.4.1 yesterday in a bid to resolve the UPnP issues that cause the Draytek 2860 to crash (which unfortunately it does not).

Unfortunately, several of our remote workers have now reported that the L2TP IPSec dial-in VPN is broken.
The error received on Windows 7 is:

Error 789: The L2TP connection attempt failed because the security layer encountered a processing error during initial negotiations with the remote computer.

Does anybody know how to fix this?

Unfortunately I cannot help, I can only agree that something bad is happening on 3.7.4.1, have a look at my post http://forum.draytek.co.uk/viewtopic.php?f=8&t=19266
