External Sites dont log, internal sites do (no replies)

Hi Guys,

I have a few websites configured inside the company reporting to piwik, it's working great.
I have an ISA2006 Microsoft Firewall that serves my incoming connections from the outside.

When I access my sites from the Outside - no piwik logging takes place but from the inside it's fine.

I tried all the proxy advice ??? nothing. My piwik server on the inside accepts both http and https ... my WordPress sites plugins are configured to talk via https ... my ISA2006 server can talk to my piwik server ?

Any advice would be great.
