[squid-users] Put all port 80, 443 http https rtmp connections from openvpn through squid?

[J Webster]

Is there a way to push all openvpn connections using http ports through 
a transparent squid and how?
Also, can I log which openvpn certificate/client is accessing which 
pages in this way?
I assume I would have to use an alternative port or use firewall rules 
to only allow squid connections from the network 10.8.x.x
