I have tried looking around on the net and searching in various was for help
with this. It is getting rather troublesome and hope to get some help.
Whenever I connect to one of our remote sites with Shrewsoft VPN after
importing our Cisco profiles, they used to connect perfectly.
Recently, and more and more often, we have had some major issues though.
1: The client will show as "connected" and "tunnel enabled", however there is
ZERO TRAFFIC. No ping, nothing.
2: Setting a static IP in the connection settings helps somewhat, but then ONLY
the last user account from the last machine that connected EVER gets traffic.
Everyone else has the above problem.
3: Even when the working client is fully disconnected and logged off, there is no
traffic, even though it displays as "tunnel enabled".
No changes in our config have occurred, it just stopped working.
Now only one machine with one user account can connect, and it occasionally
stops working there as well.
When this occurs, setting a new static IP address fixes it.
We are now running out of IP addresses to re-assign to the profile, and once
that occurs our remote sites will be completely inaccessible. They are hundreds
of kilometres away and fielded by non-technical staff who cannot be relied upon
to reboot the routers (which seems to fix the issue).
The routers are top of the line cisco 8xx series, and all the sites have the
same router.
Please, we are in desparate need of help.
Hi Jon,
Have you recently upgraded your clients from Shrew 2.1.x to 2.2.x? Can
you see if the Ciscos are complaining about (or dropping) fragmented
packets coming from the VPN client machines?
