Why does the Internet disappear when connecting to OpenVPN?

Question

openvpn

Set up OpenVPN as in this video . I also wrote push "redirect-gateway def1 bypass-dhcp" on the server to change the ip-address in the client to the server, but nothing happens ...

More specifically, the Internet just disappeared on my client and that's it. How can this be fixed?

Server:

dev-node "ServerVPN"
mode server

Answer 1

Typical mistake. The VPN server has set itself as the default route for the client. And now all packets on the Internet go to the VPN server.
The option It does not do what you think is to blame. Just comment out this option and restart the server.
push "redirect-gateway def1 bypass-dhcp"

Answer 2

On the server in the registry, you need to

HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\IPEnableRouter

set to 1.
You may need to restart the server after that.
