Adding Proxy to Tinyproxy


I am in need of some help as this is not my forte.

I have GL iNet Opal and Beryl AX
Both have LuCI with Tinyproxy and Squid.

My goal is to add a proxy to the routers so that all traffic that goes through the router goes through the proxy.

I will greatly appreciate if anyone can do a step by step guide on how to do this assuming that I am dumb and that I have 0 knowledge. That way I don’t have to come back with stupid questions.

I have a proxy that allows connections using a whitelist ip. The information I have about my proxy is IP:Port

Please help finding this solution.

Kind regards
