Hi, thanks for your reply,

I want to run gtk-gnutella inside of the I2P network using GarliCat which is the I2P version of OnionCat for Tor.

If you run gtk-gnutella on a machine without direct internet acces (the machine can only reach the I2P network via GarliCat, not the internet) there is no problem except the disutility. But if you run it on a machine with internet access it connects to the IPv4 hosts/ultras which it shouldn't.

It's wierd to have "IPv6 only" and "bind to IPv6" address options if it doesn't do that at least in my interpretation of such options. (Every linux software I ever used which is bindable to an address or interface doesn't use every interface, why should it?)
