[vpn-help] VPN Tunnel won't pass traffic

Hello Scott,

have you tried to start the Shrew Soft VPN services only on demand and
shutting them down after you disconnected from the VPN? This solves a lot
of connectivity issues in the newer versions of the software.

To start the VPN services only on demand, you will at first have to shut
them down (may require administrative privileges):
net stop "ShrewSoft IKE Daemon"
net stop "ShrewSoft IPSEC Daemon"

Afterwards, set the start type for these services to "Manually" by
importing the following registry entries:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iked]
"Start"=dword:00000003

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ipsecd]
"Start"=dword:00000003

Now, the Shrew Soft VPN services are not started automatically upon system
boot any longer. You can now start them manually so that they run only if
needed.

To start the VPN services:

net start "ShrewSoft IKE Daemon"
net start "ShrewSoft IPSEC Daemon"

Using a script, you can then also bring up the VPN connection dialog:

%ProgramFiles%\ShrewSoft\VPN Client\ipsecc.exe -r NameOfYourConnection -u
YourUserName

The disconnect is then also done by the following commands:

taskkill /T /F /IM "ipsecc.exe"
net stop "ShrewSoft IKE Daemon"
net stop "ShrewSoft IPSEC Daemon"

This works for me without problems for more than a year now.

Kind regards,

Gerd

After initial installation and configuration of the VPN tunnel, Shrew Soft
successfully connects and passes traffic to/from network devices. The
tunnel connects rapidly.
After closing/disconnecting the tunnel, subsequent connections succeed,
but slowly. After the tunnel is enabled, traffic will no longer pass.
Quitting the Shrew Soft client, rebooting the PC, have no effect.
*Workaround:*
The only workaround discovered so far is to perform the following steps in
1) Open Network and Sharing Center in the Control panel.
2) Right click on the LAN connection, select 'properties', deselect the
"Shrew Soft Lightweight Filter", click 'ok' to save.
3) Right click on the LAN Connection, select 'disable'.
4) Right click on the LAN Connection, select 'enable'
5) Right click on the LAN connection, select 'properties', select the
"Shrew Soft Lightweight Filter", click 'ok' to save.
Shrew Soft VPN Client (Std) 2.2.2
Windows 7 SP1
Dell OptiPlex 3010
Realtek PCIe GBE (Driver 5.810.1218.2012)
Cisco SA500
Any suggestions would be appreciated.
