/etc/i2pd/i2pd.conf contains number of listening ports configuration (actually 10 or more when you look for “port”). Which ones should I open in firewall so other people can connect my node? Excluding ones that are meant for management of my node. I manage the node only locally.
So far I have only open/forwarded one port, one that is set a few lines below the line “## Port to listen for connections” that certainly allows relaying traffic for other I2P peers per the http://127.0.0.1:7070/ traffic stats.

That one thats labled “Port to listen for connections” is the only one you need to forward, uncomment it and set it to a random number between 1025-65535, then just port forward the port you chose, and restart, and you should be good to go. If everything is working, you should see “Network Status: OK” in your webconsole. Also dont tell anyone the port you chose, it can be used to single out your router
