Talk:Setting up a OpenVPN server
With the default configuration set up in this how too I also believe that you need to put in a NAT table rule for masquerade like so:
iptables -t nat -I POSTROUTING -o eth0 -j MASQUERADE
Go through the "Setting up Alpine" down to "Certificates"
apk add bash bash openvpn-install.sh
Follow the prompts.
