Suggestions regarding the "connecting" page

[CapOM]

Hi,

Please find below some random topics that would be great to detail for the connection page:

• STUN requests are sent even when not using a STUN or TURN servers. For example if one of a 2 peers communication, if one is not behind a NAT then no need a STUN server but STUN binding requests will still be made.
• As a test how one could configure its router to be one of the 4 type of NAT (full-cone etc...) , i.e. what option to search in the router configuration. Are there simple tools we can use to determine what type of NAT we are behind ?
• The page does not say that TURN is an extension of STUN, so it is not something orthogonal.
• A server like coturn can do both STUN and TURN server. The page could say that one could deploy just one server to do both.
• Maybe also a section on SFU, and what are the implication for STUN and TURN. It is not a STUN or TURN server but if one SFU is on the cloud with a public IP then no need for a STUN server. But still need a TURN server for the peers behind a symmetric NAT or router blocking udp entirely (so requiring to use tcp)
• Would be great to provide a typical example where one will be likely behind a symmetric NAT. For example what kind of company or places (hotels?) are likely to use a symmetric NAT.

Many thanks!
