How to get LightSquid working for OpenVPN client traffic?

[gjaltemba]

I have Squid3 running in transparent mode and LightSquid provides reports of web usage. To get my pfsense box running as a OpenVPN client, the lan will be using a vpn tunnel interface and not the wan.

How do I get web usage reports of a vpn tunnel traffic?

Turns out all I had to do was bind Squid to my lan and specify my local cache managers.
