iVPN listening on en1

just installed iVPN, and by default it seems to listen on en0.

I want it to listen on en1.

Looking through several dozen posts, it seemed that I needed to add some data to com.apple.RemoteAccessServers.plist which I did as follows:


<key>ActiveServers</key>
<array>
<string>com.apple.ppp.l2tp</string>
</array>
<key>Servers</key>
<dict>
<key>com.apple.ppp.l2tp</key>
<dict>
<key>Addresses</key>
<dict>
<key>Addresses</key>
<string>192.168.1.6</string>
</dict>
<key>DNS</key>
<dict>
<key>OfferedSearchDomains</key>
<array/>
<key>OfferedServerAddresses</key>
<array>
<string>192.168.1.1</string>
<string>192.168.1.9</string>
</array>
</dict>


I want iVPN to listen on 192.168.1.6 (en1)
The change I made above don't seem to make any difference.

Any ideas on how to make iVPN listen on a different interface?
