Rules for "curl"

[Schubladenzieher]

I'm using TeX Live Utility on my MacBook and have LuLu enabled. LuLu then asked if I should allow/block "perl" and "curl". I clicked "allow", which enabled curl to use any address and any port. However, I was then asked if I should allow an outgoing connection (see screenshot). Can I delete the outgoing IP address? Normally, it's sufficient to allow curl to use any address and any port, right?

And one last question: What happens if I delete/disable or block "perl" and "curl"? Will my macOS system malfunction?

Thank you very much! @objective-see

Correct, the top rule will encompass the more specific one, so you can just delete the IP one (bottom rule).

If you block perl/curl in LuLu no nothing should break (at the OS level). I am not aware of macOS using curl or perl (+network) for any required system activity.

You won't easily be able to delete them (the actual binaries), as they are part of macOS, and in a read-only/SIP protected part of the file system.
