After reviewing the logs, I disabled IPv6 and it appears to reset several times (because it's the one thing that I haven't done yet). Then all the settings were put back, so I disabled it again and IPv6 finally was disabled. I read another post where this issue occurred as well. I then deleted both of my WAN adapters and added them again. Now the transparent proxy is not only functional, but now is far faster than when I installed the image months ago.
The end result: The web performance increased dramatically. I somewhat seen enhanced web performance when IPv6 was enabled before, but I'm using COMCAST as an ISP, so they provide IPv6 at the modem now (they conduct their own tests with different modems that the FCC does not test)....no tunnel is needed. This may have caused some browsing effects with the internet as IPv6 is resolved at the gateway modem.
When I enable the QoS on the WAN interface, the erratic browsing is back. Some web pages will not open and some will. In particular, SSL enabled sites take a long time opening. So I bought a new router with Streamboost technology (DGL-5500), because I wanted to plug this between the gateway router and the UTM and it has a dynamic QoS that is in development between D-Link and Qualcomm. I'm not using it to steal any bandwidth from the ISP (switch to switch) and I'm saving tons of bandwidth with caching. I re-enabled the QoS on the WAN side and the SSL sites all are working correctly. I believe this had something to do with my home router by D-Link (DIR-865L). There are some firewall settings that I believe were restricted (Address and Port restriction settings will cause adverse browsing effects as they will block incoming traffic).
