I am having trouble with routing to any hosts in the 2607:f2f8::/32 block through one of my two tunnels here with HE. The first tunnel (with a PoP in Seattle) works perfectly fine, however the second tunnel (with a PoP in LAX) is having trouble routing to any addresses in the block above.
I currently have two tunnels set up with HE. The first, (on a PoP in Seattle) works perfectly fine, however the second (on a PoP in LAX) can't route to any address in that block.
A traceroute from my system at the end of HE's tunnel:
traceroute to unixcube.org (2607:f2f8:a0e0::3), 30 hops max, 40 byte packets
1 2001:468:43f:3::2 (2001:468:43f:3::2) 79.863 ms !N 79.859 ms !N 79.846 ms !N
A traceroute from "unixcube.org":
$ traceroute6 2001:470:c:af0::2
traceroute6 to 2001:470:c:af0::2 (2001:470:c:af0::2) from 2607:f2f8:a0e0::3, 64 hops max, 12 byte packets

If I traceroute the IPv6 default gateway for my system at the other end of HE's tunnel from unixcube.org:
$ traceroute6 2001:470:c:af0::1
traceroute6 to 2001:470:c:af0::1 (2001:470:c:af0::1) from 2607:f2f8:a0e0::3, 64 hops max, 12 byte packets

Routing to any other hosts (that I've seen) work from the second tunnel (LAX), and the traceroute to unixcube.org seems to complete succesfully in HE's looking glass (http://lg.he.net/) for both LAX routers listed there. I don't think I'm configuring anything wrong, as all hosts that I have tried outside that block seem to work just fine.
Thanks,
