Which I2P ports one needs to open/forward? (lemmings.world)

/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.

i2p selects a random UDP+TCP port on first start that you have to open, the rest are usually only for internal use.

I have never used i2pd, but I think i2pd port should print which port it expects to be open. Alternatively you can set it yourself with i2pd port (your port)
