David, Have you tried the Shrew NAT traversal setting at 'force-rfc' ? I only ask, as we've had success with that on problematic connections, when other settings (including Cisco client) have failed.

Is NAT traversal set to "enable" in your Shrew client? And regarding your router, what make/model is it, and if you have configuration access to it, there is likely a setting called "VPN passthrough" which should be enabled.

If I get disconnected for whatever reason involuntarily I have to reboot the router. I don't need to reboot the computer. A little wrinkle is that I have two computers on the same router set up with ShrewSoft and even if the first one can't connect the second one can. I have been going back and forth with ShrewSoft but haven't found another solution. I'm not technical but it's like a setting in the router sticks for the first computer and can only be released by rebooting. No idea what that means in router jargon.

Keep up the good work. Recently, I have started using a Dell laptop running Win 8 Pro 64 bit. It connects to a Cisco 3825 router running IOS v12.4(9)T2. I am running Shrewsoft VPN Client v2.2.2 (Free Version). The problem: If an established VPN Connection (over Ethernet, using UTP cabling) is interrupted abnormally (i.e. not using an explicit -manual- discconnect), then, the next time VPN is -explicitly, pressing the Connect button- established (VPN seems to be established without issues), no Internet access is available (except local, on my home private network; I am on a DSL line.) Neither usual Internet access is possible, nor VPN access to our Org internal network. Pinging to known public IP addresses does not work either - so it's not a DNS problem. The situation (i.e. Shresoft VPN Client effectively not working any more) cannot be resolved in any way, except by rebooting the machine. I have tried restarting the Shrewsoft VPN Client, disabling and re-enabling the Ethernet connection, but nothing works. This is a consistent, reproducible problem. It usually happens when the laptop is put to Standby mode by closing the lid, while VPN is active. If I manually disconnect before Standby, then, after Standby VPN Client works fine to establish a new connection. If I forget to disconnect manually, it will need a reboot for the VPN Client to work correctly. The same happens if Ethernet connection (physically) drops temporarily while the VPN link is active. VPN appears to be up (by the way, I would expect Shrewsoft VPN Client to understand the outage and drop the connection automatically); If I attempt to manually Disconnect an Connect again, I find myself in the above situation (VPN Client connecting but not working). Client Configuration Details: Adapter mode is "Virtual adapter and assigned address" (Auto Address/Netmask), MTU 1380, Auto Config: ike config pull, Options: [NAT Traversal: enable, Port 4500, Keep-alive: 15 sec, IKE Fragm.: enable, Max packet size: 540 Bytes, Enable Dead Peer Detection, Enable ISAKMP Failure Notifications, Enable Client Login Banner], Authentication method is "Mutual PSK + XAuth", with ID Type: Key Identifier, Key ID string, (Remote ID: ID Type: Any) and Credentials: Pre-Shared Key. No visible errors. "ipconfig" command output does not show any difference between when (VPN is connected and) VPN is working and actually NOT working. The same problem was occurring with v2.2.1 (which I had initially tried on the same laptop). Please advise on how this can be resolved.
