Ah, right. I had completely forgotten that we've done that as part of
the bridges support (commit 69ae076). So, indeed talking to port 5353
is needed.

No, because the resolver is listening on the lo interface.

Indeed, the redirection lives in the OUTPUT chain of the nat table,
so it can't be overriden by anything in the filter table.

OK, makes sense, and I now understand why I2P is talking to port 5353 :)
Thanks!
