Hi ,
It is a bug CSCei00630 and details of bug is as follows.
When switching networks with the VPN Client connected, the client can become
attached to the previous network. It also loses touch with the MTU.
workaround :
* Shut down the VPN Client.
* Stop and start the module (don't use restart).
* Open the VPN Client and connect successfully.
Hope it helps you..Please let me know the status after doing workaround steps.
Plz rate it..
Thanks,
