ENDIAN Firewall - Proxy Content Filtering issues

I've recently installed EFW Community and joined it to my Windows AD (thank to some info I found here!). I currenlty want to use this as a method of allowing / denying specfiic website access per AD user / group (http proxy only). I currenlty use OpenDNS to do my general content blocking and would like to continue to do so (at least for now).

My issue is that the Content Filtering in EFW is doing some mighty strange things and until I fully understand it, I'd like to just turn OFF the content filtering portion of http proxy configuration. Is that possible? The documentation seems to indicate that simply setting a content filter to ALLOW all the categories under the content filter section should do just that, but that does not seem to work (I've set all the categories to the RED - ....that is turning off the filtering on those sites...corrrect? I've also tried it with them all set to green checks without the results I'm looking for). I've also set the MAX phrase value to 300, but some forum sites that some users MUST frequent are getting scored HIGHER than 300 and are being blocked.

I want to ONLY use the whitelist/blacklist feature under the http proxy for my filters...is that possible?
