I have a VPN connection set up using the Cisco VPN Client, and whenever I connect to it I lose my internet connection. This is the first time I have used this software, all previous VPNs I have used have been setup through Windows and I can uncheck the 'use remote gateway' box in the TCP-IP properties box to get around this.

Is there a similar option in the Cisco Client that I am missing? I am running on Windows 7 32 bit

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 enter image description here
  4. Uncheck NetBalancer LightWeight Filter or Connectify Lightweight Filter enter image description here
  5. Click on OK and try connect to VPN now

  • @Lupocci NetBalancer is a Windows application for local network traffic control and monitoring.

  • For me worked disabling IPv6 on both connections (Cicso and internet connection). Mar 3, 2020 at 18:48
  • I can't see any of these 2 options. Any other option?

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.

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).

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.


When a remote user connects to the a secure gateway, the VPN Client can receive a web browser proxy setting from the secure gateway and then change the web browser proxy configuration of the user to operate within the organization's environment. This setting is in effect only while the user is connected to the secure gateway. When the user disconnects, the VPN Client automatically changes the browser proxy of the PC to its original setting.

  • IS there any way to circumvent that?
