Teamviewer VPN blocked by Windows Firewall

teamviewerwindows-firewall

I am using Teamviewer 9 and would like to use the VPN option. I installed it all and it works perfectly only if I turn off the Windows firewall on my VPN target. Teamviewer.exe ia already allowed through. Does anyone know what rules I need to setup to let the VPN tunnel through? Both machines are Windows 8.1.

I also had this problem, and it could also be easily bypassed by turning off firewall - however I said NO to that solution (for security reasons).....

I solved this by setting sharing options (no Firewall settings were needed):

  1. Go to Control Panel => Network and Sharing Center
  2. On the left, click on Change advanced sharing settings
  3. Expand the network profile your TeamViewer VPNetowrk is in (probably Public profile)
  4. SOLVING POINT: In sub-section File and printer sharing choose Turn on file and printer sharing
  5. (optional but security) As you may be on more public networks, not just TeamViewer VPN:
    For security reasons you should also set this in that network profile:
    • Network discovery => Turn off network discovery
    • Public folder sharing => Turn off Public folder sharing (...)
    • Password protected sharing => Turn on password protected sharing
    • If you can, choose the best encryption you can (probably 128bit)
