Re: [6bed4-devel] Success general NAT traversal/bypass with just Neighbor discovery

[<ebi...@xm...>]

The implemtation I am following up on has two deficiencies.

- Only one target link layer address advertised.
- No ability to find the route the peer is using.


The first is a Doh.  Icmpv6 supports specifying the same option multiple
times.

The second is also a Doh.  We just need neighbor advetisements sent
by consulting the neighbor cache.  The standard behavior if someone
has not specified a link layer address.  Silly me for not implementing
that.

With those changes the will work for any NAT scenario I can think of.
And the algorithm is about as minimalistic as it gets, and reasonably
proof against spoof packets doing something bad.

Anyway here is a snapshot of my latest code.
