Route all the traffic through OpenVPN server
Posted: Tue Jun 07, 2022 10:50 am
Hi there,
I have set up OpenVPN on a server. I am able to connect to OpenVPN as a client. I want to route all the client traffic from the OpenVPN server. I have read all the documentation and tried to follow it but still unsuccessful.
Here is my configuration details:
Server configs:
Client configs:
On the OpenVPN server:
Add the following line in the /etc/sysctl.conf
confirm it with "sudo sysctl -p" command.
Add the following in the firewall rules /etc/ufw/before.rules
Kindly guide me if I am missing anything. I have taken all the steps but it is not working. Thanks
