No internet connection with Cisco VPN

Solution 1:

Some softwares conflict with Cisco AnyConnect, as in my case. Had NetBalancer installed and it would stop sending/receiving any packets as soon as I would connect to VPN. another program that I know to conflict is called Connectify.

You can refer to cisco website : Cisco Website

What I did is as below :

1. Click on network icon on bottom right → Open network and sharing center
2. Click on change adapter settings on top left
3. Right Click on Cisco AnyConnect Secure Mobility Client Connection → Click on properties
4. Uncheck NetBalancer LightWeight Filter or Connectify Lightweight Filter
5. Click on OK and try connect to VPN now

Solution 2:

The nature of the VPN connection from the Cisco device at the remote location is to tunnel all traffic for routing by the remote location. This includes your Internet traffic which is then denied by the remote router.

You will need the VPN administator at the remote location to enable split tunneling. Assuming that the network doesn't conflict with your local address pattern (which is most likely 192.x) then you should be good to go.

Solution 3:

I had the same issue, and I tried to disable TCP/IPv6 and in the cisco anyConnect secure connection. It worked just fine. Especially, if you are connected to Verizon hot spot that is most likely to be the issue (IPv6).

Solution 4:

If your are using it for a specific IP range, you can try adding static routes via command prompt and deleting the default route. That will work but it may require a little manual route modification.
