Open TCP/UDP and HTTP port on node in pf(packet filter) MacOS Monterey (intel processor)

[Ralledev]

Hello, i going to start run a Celestia node, witch is a Web3 project in testnet. Im just installing the node with Homebrew, and are in this state of the install:

In the guide does it state to open these ports on these different protocols, I'm not used to Mac nor it's syntax at all and I really want to get this part right, so I don't mess up the pf and shooting myself in the foot. Shall i open the port here in this state of the install in the image above? or in a new terminal?

anyways the config and port to be opened is (image below):

So how do I move on?, I don't want to do over the whole installation process so I will have my terminal open in Homebrew, as stated if the first img. The guide to install the node and open these ports are in their docs here:

Install celestia-node | Celestia Docs

Learn to build and install celestia-node.

docs.celestia.org

Also as stated in the headline is a Macbook air with Monterey as OS with an Intel i5.

I hope there is a networking dev on MacOs here.. because i'm lost in the blue right now...

Thanks,
Regards Rasmus

Have you tried and it doesn’t work?
As far as I know, there are no blocked ports by default on macOS.
The firewall can be enabled, but it’s not enabled in a regular installation.

have no idea, but I still need to add the "flags" to make it work. I don't know how this should look in packet-filter.

as @bogdanw srated, the ports should be open. There seems to be no particular problem if you provide the core ip, gateway ip, etc. as printed out - and running it first from the shell allows for nice debugging… and you can kill it a any time “not shooting yourself in the foot”. 🤓

Are you asking how to get your internal and external IP address, as well as the one from your gateway?

run ifconfig or ifconfig -a. This command shows you the list of interfaces along with their IP and MAC addresses. You can also use ifconfig en0 or ifconfig en1 for the configuration of a particular interface only (en0 is typically the wired Ethernet while en1 is the WiFi interface).

netstat -i will list all interfaces and will show you the IP addresses assigned to each of them.

If you're the OS Primary interface and primary IP address, you can use the scutil.

to see you external IP use e.g.: wget -qO - http://ipecho.net/plain; echo

Thank you for explaining, now I feel way more comfortable in continuing now, then I will just in the first image provide the nessicary info about gateway, ip etc... and if I bump into something I do. Sweet that they're open by default makes the process much easier. I will just login into the gateway alos and open the port there so the gateway wont block any incoming signals from the network, I guess.

Thank you for a clear provided answer + other useful information around the topic, many thank to you!
Have a great day!
