I did not know it could also check Layer 2 and Layer 3 addresses this way seems more secure

Hello fellow Squid Accelerator/Dynamic Cache/Web Cache Users/PfSense users
I think this might resolve any container based issues/fears if they happened to get into the cache. Ie a Docker Proxy got installed and tried to data marshal the network card inside of a freeBSD jail or something like that. Biggest fear with my cache it is a big cache now
Please yet me know what you think or if it is wrong.
Here is my configuration. I wanted to share it as it might help to secure some of this.
Keep in mine I use cachemgr.cgi within Squidlight so I had to set the password and I have to also adapt the php status file to include the password and also the sqlight php file.
After that the status and gui pages work still with the new password. Only issues area that it shows up in clear text when it goes over the proxy I can see my password clear as day again that was an issue listed inside the Squid O’REILLY book also.
I am amazed at the warm updates that was the original goal I was tired of slow updates over and over again.
