L2TP/IPSec NAT-T


Recommended Posts

Hi,

Now,I am verifying the L2TP/IPSec NAT-T connection by using the Vista business.

However, cannot the connection.

Error is 789.

The following registries are changed on the Vista side, and it rebooted.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\PolicyAgent

AssumeUDPEncapsulationContextOnSendRule=2

The VPN server used Cisco VPN3030(firmware 4.7.2J).

It fails in Phase1 in the log on the VPN server side.

But It is possible to connect it without trouble when going with XP SP2.

What is thought as a cause?

Regards

Is this a case of jumping the gun too soon before Vista is really ready for most computers or programs? There are mentions of the problem in the link below, but no mentions of Vista. I expect to see a lot of Vista problems on here in the coming weeks.
