As part of the series of tea time talks we do within Collabora, I recently got to refresh my knowledge of STUN, TURN and ICE (the protocols for NAT traversal) and give an introductory talk on how they all fit together within the context of libnice.

Since the talk might be useful (and perhaps even interesting) to a wider audience, I’ve made it available: slides, handout and source (git). It’s under CC-BY-SA 4.0. Please leave comments if anything is unclear, incorrect, or could do with more in-depth coverage!
