The software we're running now (an old NetBSD release) doesn't support
6to4, ISATAP, any of the automated tunnel schemes. Bill Sommerfeld
and I had talked occasionally about updating it to a newer version
(the 1.6 series supports 6to4 and IPsec, and -current supports ISATAP)
in our "copious free time", but it hasn't happened yet.
Even if we do update, the approach to use for 6to4 bears thinking
about. We could set up a single 6to4 router for the campus, but it
might be more practical to do it for each subnet, at least where the
local IPv6 routers support it. Then IPv6 traffic on campus would be
less dependent on one central point. However, that makes the
addresses of machines on those subnets subject to changes in the IPv4
address of the IPv6 router. They're fairly stable, but not nearly as
much so as, say, the IPv4 routers run by the Network group.
We should have routing *to* 6to4 addresses now, thanks to a router
Greg Troxel is running at RLE. I don't know if it's working as an
open gateway you could use to connect back from a 6to4-only site. As
far as I know, Microsoft is still running an open 6to4 relay.
If you're looking for connectivity between a network of your own and
MIT, we could set up a tunnel -- either delegate to you part of MIT's
address space, or an ordinary tunnel to whatever block of addresses
you may be using. (We do need a fairly static IPv4 address for your
end, though; all the configuration updates are currently done
manually.) Just let me know what you're looking for....
