respond. And the answer is no: No packets are reaching the gateway. So
currently i guess, that the "Shrew virtuel Adapter" is the reason
bacause it get's not enabled while i try to establish the connection. I
cannot see any error messages. The Win7 machine - SP1 with all patches -
is standalone / no domain and it's an out of the box installation - no
other software on it. Regards, David On Wed, 15 Aug 2012 22:31:03 -0400,

earlier in this mailing list: Win7 64Bit SP1 client (German) with Shrew
VPN Client 2.1.7 (and 2.2.0 beta, separetly tested). Trying to connect
brings me to the "negotiation timeout accoured" message. Checked the
adapter settings (Filter) with all tried media (Mobile Phone, WiFi,
Ethernet/cable) Using WinXP / SP3 (german) everything is working as
exprected with every media (mobile, WiFi...) Using a LANCON 1722 VPN
Gateway with the lates Firmware (LC.OS) Attached you'll find an IKE
trace log. Any help would be highly appreciated! I would first check the
VPN gateway logs to see if it even sees the Do you have any other VPN
software installed on the Win7 mac

Based on the trace log you sent and your comment about no

reaching the gateway, negotiation does not even start in your case.
