Some weeks ago I started to work in documenting how to setup 6to4 and Teredo
relays/servers in several platforms for the afripv6-discuss mailing list.
There are many 6to4 relays already, but it becomes even more important to
have them where the bandwidth is more expensive, because it avoids traffic
going thru upstream links. The first message on this is here:

More information about 6to4 also available at:

Similarly for Teredo:
