Reading sites for things like #IPFS and #Beaker / #DAT and #MaidSafe / #SAFENetwork, some things are never stated.

If someone were to set up a #RasPi to be a node on one of these types of #peer-to-peer networks, would they need to set up NAT passthrough, or do their protocols already include something like STUN / TURN?

Mostly an academic question, as I’m not willing to potentially open up access to my home network.
