Hi Kevin,
thank you for your 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

Hi all, have the same
connecting problem as it was posted 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!
Hi David,
The "resend 1 phase1 packet(s) [0/2]
172.20.10.5:500 -> xx.xx.xx.xx:500"
messages in the trace log suggest
that either the packets are not
getting to the gateway or the gateway
is ignoring the connection request.
I would first check the VPN
gateway logs to see if it even sees the
traffic from the Win7
machine.
Do you have any other VPN software installed on the Win7
machine? Is it
part of an Active Directory Domain?
Hi David,
My understanding is that the Shrew Soft Virtual Adapter does not get
enabled until the negotiation has at least partially progressed with the
VPN gateway. Based on the trace log you sent and your comment about no
packets reaching the gateway, negotiation does not even start in your case.
I have a few questions for you:
1. Is the Win7 machine a laptop? Does it have the Microsoft Virtual
WiFi Miniport adapter enabled? If so, uninstall Shrew, disable the
Virtual WiFi adapter, reboot, then install Shrew again.
2. The Windows XP machine that works, is it on the same network as the
Windows 7 machine? Are they behind a NAT so that VPN gateway sees them
coming from the same IP address? If so, can you try disconnecting the
other Shrew clients, wait 15 minutes, then try the Win7 machine?
3. Do you know how to use Wireshark to do a packet capture? If so, can
you do a capture to see if there's packets coming from the Win7 machine
going to the gateway?
