How can I configure an OpenVPN server on a Linux machine to only listen on given interfaces? Are there any features like this in OpenVPN?
At the start of your sample configuration file (that i suggest to copy from
/usr/share/doc/packages/openvpn or /usr/share/doc/openvpn-2.0, you have the following:
# Which local IP address should OpenVPN # listen on? (optional) ;local a.b.c.d
Here you have a great official installation/configuration guide for OpenVPN, that i suggest you step forward with it since OpenVPN isn't a simple configuration.
