well gnutella is almost dead, the only usable client is gtk-gnutella https://sourceforge.net/projects/gtk-gnutella/, but there's not enough users. You might be lucky if you find anything you want.

For ed2k, you have amule https://github.com/amule-org/amule/releases/tag/3.1.0 . This network still has around 100k users (a drop in the number of torrent total users - but it's around the same number of users of soulseek) but you can still find lots of stuff there. Lately the amule client has been improving and improving and currently it's the best client for ed2k - my opinion.

For you to have high id you need to have 2 ports open, and some vpn don't allow that. They only allow one port. With ed2k you can search the network (imagine like searching directly the bittorrent DHT), or you can use any ed2k link sharing community to get the stuff you want - this way is safer

It’s a bit suspicious to recommend two protocols as I question if you use it yourself or just looked it up.

Well, i'm old enough to have used almost everything. And i like to know how stuff works.
