Squid3-dev SSL MITM Proxy Mode Not Working

[tk]

I'm in the process of implementing a new pf 2.1.5 amd64 installation and fudging around with the Proxy - Trying to get it as close as possible as a different fw product.

Having troubles with Squid3 Dev -

Transparent Proxy (http/https) works
Proxy (3128) (http) works
SSL (3129) (https) doesn't work.

netstat -an |grep 312 only shows the http instance listening.

–

Really need the Proxy mode (non transparent working) so I can start performing content filtering via Dansguardian and auth via NTLM (which works with 3128, but when I try to visit an https site I just get a blank screen).
