VPN connects but wont allow to connect to ip or internet

I did not renew my subscription to Cylance software and it uninstalled itself.

Since that time Cisco and Forticlient both will connect but does not allow me to access the internet and IP’s I accessed before.

  • We used Cylance removal tool to remove anything that their uninstall didn’t remove
  • Cylance support was great to work with, but couldn’t resolve the issue
  • Cisco refused to talk to me, worst support ever.
  • We have uninstalled Cisco and Forticlient and reinstalled them, didn’t help
  • We have updated the drivers, didn’t help
  • We ran without virus protection, didn’t help
  • We tried to create a windows vpn for cisco, it didn’t come up with the user and password prompt.
  • Ping does not work
  • Trace routes shows that not even one entry gets a hit

The problem is on the window side. That is won't allow the DNS address to be setup.

The VPN’s do connect, show connected, but wont allow any ip traffic to leave the laptop.

Any ideas?

    Hello，

    Thank you for posting in Microsoft Community forum.

    Depending on the scenario you described, the issue of a successful VPN connection but no access to the internet or IP address can be related to several factors. Here are some possible solutions and suggestions you can try:

    1. Try resetting the network adapter: Run in the command prompt as an administrator:

    netsh int ip reset

    netsh winsock reset

    ipconfig /release

    ipconfig /renew

    ipconfig /flushdns

    1. Manually set up DNS: In the network adapter settings, select Internet Protocol version 4 (TCP/IPv4) and manually set the DNS to:

    Preferred: 8.8.8.8

    Standby: 8.8.4.4

    1. Check Firewall: Temporarily disable Windows Firewall and see if that fixes the issue.
    2. Check the route table: Run route print to make sure the VPN route entry exists.
    3. Update Network Drivers: Make sure your network adapter drivers are up to date.
    4. Run the network troubleshooting tool: Right-click on the network icon and select "Troubleshoot Issues".

    I hope the information above is helpful.

    If you have any questions or concerns, please feel free to let us know.

    Regards,

    Jill Zhou
