I want to test something locally. For that, I'd like to be able to drop outgoing packets sent to a specific host/port. I tried messing around with pf rules using Murus (the non-free version), but have been unsuccessful.
I am comfortable in the terminal, but am unsure where to make any changes and how to apply them. I am familiar with iptables on linux.
Can I get some direction on how to achieve this?
