[vpn-help] ShrewSoft 2.1.7 and 2.2.0 Issue

[Darren Nye]

Hi all,
 
VPN Client: ShrewSoft 2.1.7 and 2.2 Alpha 9.
Windows: 7 64bit and Vista 64bit
Gateway: Juniper SSG5
Gateway Hardware Version: 710(0)
Gateway Firmware Version: 6.3.0r5.0 (also tried firmware 6.0 with same
issue).
 
Five people in different locations, have been able to duplicate this
problem, with the ShrewSoft 2.1.7 and 2.2 Alpha 9 clients.

However when we use NCP Client or Green Bow VPN Client, we do not have this
issue and everything seems fine. So this points to either a configuration
issue with ShrewSoft or a bug. I hope someone can help?
 
We can connect to the Juniper with ShrewSoft and also connect to our network
file servers, and perform short tasks such as copy small files up/down or
use remote desktop.
 
However, when we try to use Windows Explorer to connect to a Linux/Samba
(v3.1) file server (ie: \\192.168.66.1\printfileserver
<file:///\\192.168.66.1\printfileserver> ) and copy a folder with a large
number of files (100mb or more) - by dragging and dropping from the server
to the desktop - it seems that Windows thinks the connection to the server
is lost - although the tunnel itself in ShrewSoft doesn't show that it
disconnected. But the log file seem to show a "halt" command around the same
time the issue is probably happening.
 
See attached:
 
Windows-preparing-copy.jpg = the beginning of the file copy - things going
normal so far
 
Windows-copy-start.jpg = after windows is finished preparing (I believe
figuring out how much and what it's going to copy) - it then tries to start
the copy - but never seems to start
 
Windows-failure.jpg = a short time after the windows-copy-start above,
windows will display a failure. It's at this point that shrewsoft perhaps is
getting the halt.
 
The Shrew trace and other log/dump files are attached. 1.1.1.1 is a changed
IP address but represents our internal IP address of the Juniper router.
 
These particular logs were when connecting via ATT and my cell phone.
However we've had these issues remotely from homes on Comcast and Optimum
cable modems.
 
I've been told by our Juniper tech rep that our internal servers are sending
a RST (reset) although I don't see that in any of the logs I'm looking at.
 
But we don't experience these odd issues when using the NCP client or Green
Bow. But I'd rather not license every single one of our users.
 
Any suggestions, please let me know.
 
Thank you!
