Which I2P ports one needs to open/forward?

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.

None are required, and it’s intentionally randomized and supposed to be handled through uPnP. That said, as far as I know it’s only listed on your router’s Config -> Network page. None of the ports actually listed in i2pd.conf are the ones you need, although if you need to make it fixed and manually specify a port, look for the one that says it is “randomized by default” and put your own randomly chosen port there. Do not use the default port from the config, it’s intentionally supposed to be unpredictable.
