Replace x.x.x.x with your VPS public IP address. You should probably include those lines in the openvpn init file in /etc/init.d . Technically, only the last line may be necessary. There are probably better ways but this should work. I use CSF firewall and I added those lines to csfpre.sh instead.




Hello tomfra,

thank you for this HOWTO.

It works.. But only if I set a public IP to the VPS.

If I set an internal IP to VPS like 192.168.1.5, (for testing) I can use it as a webserver ( =>can reach from outside), but openvpn doesn't work..

What should I do to get it working?

Thank you..
