[vpn-help] WG: Problem with

Tue Oct 2 02:19:06 CDT 2012

Hello all again,

in addition to my problem described below:

Shrew Soft Virtual network adapter:

It seems that the adapter, when installed, is down. Enabling the adapter via Device Manager: No Error, but the entry disappeared! However  it is still installed... When I stopped the shrew soft services and installed the software again on top of itself (trying to the hint of Terry chambers) there are to shrew soft virtual adapters displayed in the device manager, both down. Seems whatever I do shrew soft virtual adapter is always reported to be down. And the client does not work properly.

Any ideas ?

T.i.a and regards

Betreff: Problem with 

Hello all,

We have a Problem concerning Shrew soft VPN Client running on Windows 2008 Server SP1.

Setting:

Virtual Windows Server 2008 R2 Standard Service Pack 1 running on VMware ESX Server.

Our Firewall allows Traffic (Port 500, 4500) from/to this Server

Shrew Soft VPN Client (Version 2.1.7) was delivered from customer including several Profiles.

Shrew Soft VPN Client was installed without Error messages on that server.

Profiles from Customer had been imported without error.

Starting the client leads to the following messages

config loaded for site 'Atos3-TSK'

configuring client settings ...

attached to key daemon ...

peer configured

iskamp proposal configured

esp proposal configured

client configured

local id configured

pre-shared key configured

bringing up tunnel ...

negotiation timout occurred

tunnel disabled

detached from key daemon ...

The client does not work reporting:  "negotiation timeout" 

We sniffed the packages send from (received by) the server and noticed, that the client sends packages for IKE Phase1to the customers Firewall and the customers Firewall answers, but...

It seems that the client could not catch the packages send from customers firewall, because it sends the first request several times...

We Installed the client on several laptops running XP or WIN 7 and the client works properly (each test machine has been connected to the internet using the wireless LAN Adapter).

Additionally the Client works properly when it was installed on a virtual Win 2008 Server running with VMware Player on a WIN 7 Machine.

My question is: 

Why is it not possible for Shrew Soft VPN Client to establish the VPN Tunnel ?

Thanks in advance for help and 

Best regards
