HTTP Proxy and DNS

burtoncarl
I've recently upgraded from 7.011 to 7.104
I use the HTTP Proxy(transparent) and the Content filter
After upgrading it doesn't appear that the http proxy is able to get DNS resolution.
When I turn off the proxy the requests go through fine.  When it is on though I receive an error page saying: 

While trying to retrieve the URL: 	http://google.com/

    Jack,

    Correct.  If I turn on transparent mode, the above logs are what I see, and I cannot browse.  All I get back is the DNS resolution timeout error page from my Astaro box.

    Once I turn on Standard mode, I am able to browse just fine.  Nothing is reported in the 'Web Security Statistics' windows either.  Before, with Transparent mode on, this would be populated.

    Doing DNS lookups gives no results.  I get 'DNS lookup did not deliver a result'.  This is in Standard and Transparent modes.
