6to4 to HE not working

I have a 6to4 router and one using HE's tunnelbroker service and they cannot talk to eachother, but both can talk to tunnelbroker.net

I think there may be a routing problem somewhere.

Code (6to4 to HE) Select

Seeing as this had nothing to do with the cert threads, I moved it here.

How is that 6to4 configured, a /48? a /64? Is there a machine running on 2002:44ab:10fa::/48 (or ::1/48) and then yuo are splitting out the specific /64 to your lan and acting as gateway?

OK, sorry about that

I have a Router configured having 2002:44ab:10fa::1/64 (have also tested /48) on it and it hands out multiple /64s and acts as the main gateway.

What does a traceroute to 192.88.99.1 from either location show you for path. I'm not certain if it is someone else's relay causing issues or what.

Ok so Sprintlink doesn't seem to complete the trace, but your machine actually using 6to4 does?

Also what is up with that crazy latency on your sprintlink trace, does it really start off that bad at 400ms?

Even traced to that first 400ms hop in your trace, and it isn't that bad from the tunnel-server, so no idea where your machine using the tunnel is going for the well-known 6to4 anycast:

Yes

yep, it really starts out that bad (sometimes I have around 100ms at best).
