I've gotten multiple emails about this... Yes, this is a known issue at the moment due to an upgrade put in place at DeLong. There is an open ticket with Juniper on why the 6in4 tunnels are not working on the SRX-100 and why traffic coming in through the alternate path is not being correctly processed. I hope to have my IPv6 services back on line shortly and I apologize for any inconvenience and the unfortunate timing. Owen On Apr 2, 2010, at 2:22 PM, Jim Burwell wrote:

FYI ... I can't get to delong.com's IPv6 space from my HE tunnel provided IPv6 space (2001:470:8332::/48). When I traceroute using UDP or ICMP or tcptrace it stops in HE's core. BGP issue?

Last hop I see is: 10gigabitethernet1-1.core1.sjc2.ipv6.he.net (2001:470:0:31::2)
