I am trying to follow this guide:
https://openvpn.net/index.php/open-source/faq/79-client/255-qconnection-initiated-with-xxxxq-but-i-cannot-ping-the-server-through-the-vpn.html
To open up the TUN/TAP interfaces to all traffic.
The guide says:
On Windows XP, the firewall can be accessed by Control Panel -> Security Center -> Windows Firewall -> Advanced. In the Network Connection Settings control, uncheck the box corresponding to the TAP-Win32 adapter.
I can't find any equivalent information for Windows 10.
