I think we could be a little more flexible than that too. As long as a 
bootstrap peer can allow some devices to join the overlay and is not reachable 
by every node in the overlay it can still function as a bootstrap peer. A node 
behind a NAT at a small office may be a bootstrap peer for nodes in that office 
since it is part of a larger overlay although it is not reachable by every 
member of the overlay.

What Jiang suggests is definitely an improvement over the current definition.

Best,
Saumitra

Subject: [P2PSIP] 回复 :Re: Bootstrap peer reachability in 
draft-ietf-p2psip-base-00

Hi,Dean:

Maybe a term named "publicly reachable" should be added. With the new term, we 
can be clear on the semantics of "public".

I also defined the term in 
draft-jiang-p2psip-relay-00(http://tools.ietf.org/id/draft-jiang-p2psip-relay-00.txt)
 as the follows:

  publicly reachable: A node is publicly reachable if it can receive
      unsolicited messages from any other node in the same overlay.
      Note: "publicly" does not mean that the nodes MUST be on the
      public Internet, because RELOAD protocol may be used in a closed
      system.

Hope it is helpful.

Regards
Jiang XingFeng
