Hi,

I see mixed connections. How can i have ONLY i2p connections and nothing else?

Thanks

right click a torrent and go to networks. turn off (un-check) internet
do this for any torrent you want to just use I2P

Great thanks, works ok.

Is there a way to make it default for each new torrent i add?

on the transfers tab, press the add button in top-left corner.
on the 'open .torrent file' tab there is a choice at the bottom-middle for I2P-Internet-All, uncheck internet
