Can other people connect to the proxy I set up, or is it just for me? Alternatively, for a slightly more dir

"Hey guys, quick question—can other people connect to the proxy I set up, or is it just for me?

I set up a proxy on my machine (using Squid, if that matters), and it works fine for my own stuff. But I’m kinda curious if friends or, uh, *unwanted visitors* could also hop on it.

How do I even check that? Is there a way to see who’s using it, or do I need to tweak some settings to lock it down?

Also, if it *is* open, how risky is that? Don’t wanna wake up to some random dude hogging my bandwidth lol.

Thanks in advance for any tips!"
