Hi there, I have the task to establish a VPN connection to a Windows 10 pc from outside. The pc is inside on a double network structure. I did all the steps from the HOWTO regarding key creation and all that stuff I also installed OpenSSL for the openssl.cnf. My problem is I think that I have some errors with the routing. I will post the picture of the network structure and VPN connection log, hopefully someone can help. [url]https://imgur.com/a/yVNdT[/url] [url]https://imgur.com/a/XqMaJ[/url] The TLS Error is not reffering to CA or other certificate. When I try to connect from outside I dont even come to establish a connection with the pc. On the FritzBox router I configured the UDP port, but could not se any route from the OVPN network (10.0.0.1 etc.) do I need to make the route from the Zyxel router with the OVPN network? (Destination: 10.8.8.0 with the next hop the network inside?) thank you for helping trelosgiadesimo

OpenVPN on Win10 Installation Problem

Hi there,

I have the task to establish a VPN connection to a Windows 10 pc from outside.

The pc is inside on a double network structure.

I did all the steps from the HOWTO regarding key creation and all that stuff I also installed OpenSSL for the openssl.cnf.

My problem is I think that I have some errors with the routing.

I will post the picture of the network structure and VPN connection log, hopefully someone can help.

The TLS Error is not reffering to CA or other certificate.
When I try to connect from outside I dont even come to establish a connection with the pc.

On the FritzBox router I configured the UDP port, but could not se any route from the OVPN network (10.0.0.1 etc.) do I need to make the route from the Zyxel router with the OVPN network? (Destination: 10.8.8.0 with the next hop the network inside?)

thank you for helping

Check your server log for connection attempts.

There will not be any because you have probably not enabled port forwarding correctly ..

Should I port forward on both routers?
Which other ports except the UDP should I forward?

I forwarded UDP port 1194 on the 192.188.188.1 router but still no connection.
Do I have to do that also on the other router?
