So I guess everything is okay with Routers and Firewalls. On Client side i think i have tried everything already. Disabled Firewall, disabled anti-Virus, remove any 3rd Party Software, etc, etc. But at the Moment they also have no clue. I have no idea if the Problem is on utm or Client side.
Andreas, It's difficult to read the log with debugging enabled. Plus, I think the problem is after what you posted. Please disable debug and show us the IPsec log from a single connection attempt. Cheers - Bob Sorry for any short responses. Posted from my iPhone. Hi Bob, here we go: fw pluto[]: packet from We're getting closer.
The problem is after those lines. A single connection attempt will be about 60 lines. Cheers Bob. Hi Bob, sorry for my late resonse. Or you can contact the technical support of the manufacturer.

Monday, February 8, PM. Did you have any luck HR-Damir? I am having the same problem, XP works fine, Windows 7 doesn't. Wednesday, February 10, AM. NKumarnz, I didn't have success But if I use adsl router then works only XP.
Maybe somebody have some idea? Thursday, February 11, AM. I open a ticket with Microsoft because I could not find anything. They have been working on it for more than a week and its does not look like they are finding much on it.
I am pretty sure that is has to do with that extra information in the IKE packet. Hope some one can figure this out. Thursday, February 11, PM. Oddly enough, the IPSec Policy Agent service itself does not need to be started, on my system it is set at manual start and it does not even start when connecting over L2TP.
Make sure UDP port and are natted from the firewall to the server 4. On client create the L2TP connection, use the proper Preshared key defined on the server Works like a charm.

Once I set the mode to "Automatic", it worked! Tuesday, January 11, AM. Friday, January 21, PM.
Because of the way in which NAT devices translate network traffic, you may experience unexpected results in the following scenario:. If you must use IPsec for communication, use public IP addresses for all servers that you can connect to from the Internet.
Log on to the Windows Vista client computer as a user who is a member of the Administrators group. If the User Account Control dialog box is displayed on the screen and prompts you to elevate your administrator token, select Continue.
It's the default value. When it's set to 0, Windows can't establish security associations with servers located behind NAT devices. When it's set to 1, Windows can establish security associations with servers that are located behind NAT devices.
