Web proxy, Transparent Proxy, Squid caching

[guest25156]

First off Thankyou for viewing my msg. If you can help this would be so great.

After 3 days of trying to get Transpartent Web caching working with Squid. But I have had no luck. I must be missing something.

I don't understand these links.
https://docs.opnsense.org/manual/how-tos/cachingproxy.html
https://www.tcptechs.com/opnsense-transparent-caching-filtering-proxy-with-virus-scanning-step-6-transparent-proxy/


I need step by step instructions. A video would be nice.

Hello Niktronics,
Sadly right now I won't be able to provide a step by step instruction nor a video.
I suggest you follow this order of sections in the (2nd link) : 3, 5,6-8, 2&4, 9.

generally, the steps should be:
1-Deploy a caching proxy and test if it works in a browser
   A-configure the proxy
   B-Add a rule in the firewall to allow connection to the proxy on your port of choice and make it precede all other rules
2-Turn it into a transparent proxy and test with HTTP and https sites:
   A-configure the proxy and add a self-signed certificate (if you plan to read and filter encrypted SSL traffic)
   B-Forward all HTTP and HTTPS traffic to the proxy (this can be done through Firewall rules > NAT >port forwarding
   C-Add Firewall rules to allow the forwarded traffic to the proxy
3-Add virus scanning if you want to and deploy the certificate with GPO or any other means
