Example Network
The following config files and settings are configured for the following network scenario.
Your home router’s IP address is 192.168.1.1 and its subnet mask is 255.255.255.0
The OpenVPN server that you have attached to that router has its network interface manually set to the IP address of 192.168.1.150 with the subnet mask 255.255.255.0 and a default gateway of 192.168.1.1
The router is configured to port forward port 1194 to the server’s IP address of 192.168.1.150
If any aspect of your network is different than what I've described previously, you'll need to take that into consideration when following the rest of this guide.
