hello HE.NET
did you drop the 6to4 delegated prefix 192.88.99.0/24 ?
if yes please would you drop it from your BGP routing table anounced ?
thank you

Hi!
For issues like this please email i...@he.net or n...@he.net with IPv4
and IPv6 traceroutes to the addresses involved.
We are running and announcing 6to4 relays globally.
We did recently turn on IPv6 RPF facing our 6to4 relays. This was done
for basic network security reasons.
There has been no change in traffic levels through our 6to4 relays,
however it does appear to have affected a very limited number of people
(I know of 1 other we already helped, you would be the second if this is
your issue) that were using our 6to4 boxes to de-encapsulate packets
with IPv6 source addresses not in the IPv6 6to4 range.
If this was you, the fix is to either:
1) interconnect natively with us and announce your IPv6 address space to
us via BGP (and don't use 6to4)
2) use your own already existing native IPv6 connectivity with your
address space (and don't use 6to4)
3) make packets that you send to our 6to4 relays source from your 6to4
interface with your IPv6 6to4 address
or 4) request a IPv6 BGP tunnel and run BGP so that you can announce
your address space to us (and don't use 6to4).
If you email us we can work with you to diagnose your specific situation.
Mike.
