[strongSwan] Binding StrongSwan to a specific IP address instead of 0.0.0.0.

[assiduus]

Hello. 

Basically my whole question is in the topic. :) 

While there is an option to change the port (_left|rightikeport =
<port>_), I can't find the same for the IP address to listen on (bind
to). Is it possible at all? 

Cheers.
