Enabling floodfill--What it does?

[eepman]

If I enable the floodfill from /etc/i2pd/i2pd.conf file, what happens? How do I help the i2p network? From my home router, I have limited the single board computer that's running i2pd to 3 MiB/s download 2 MiB/s upload bandwidth. Would that bandwidth still help the i2p network in floodfill mode?

When you're floodfill you participate in storing LeaseSets (destination addresses basically). Essentially on top of relying bandwidth you also participate in securing network consensus. I believe it requires a bit more CPU and bandwidth. Your bandwidth should be fine, I think you should enable it. Actually on the Java app if your node is good it's enabled automatically. Also I believe the network tests your node and approves it if you're not malicious but I'm not sure.

I enabled it some weeks ago. It indeed seems to use more CPU, but that's OK. The increased bandwidth is OK, too, as I have my single board computer's BW capped on my home router anyways (to 3 MB/s up&down). Is this BW enough to help the i2p network as a floodfill node?

Also, in i2pd docs [1], it says, "You can enable floodfill only if it has public ipv4 address". My i2pd node is running on my home network behind a CGNAT, so I don't think I have a public ipv4 address. Is this a problem for acting as a floodfill node?
