I'm trying to build HE tunnel for a few days now without success, so I decided to ask for help. Once I configure the tunnel not even P2P IPv6 ping is not working. I'm using c181x-adventerprisek9-mz.151-4.M12a on Cisco 1812 router. In order to access Internet I'm using dialer (pppoe) and here is a relevant part of my configuration:

ipv6 unicast-routing
ipv6 cef
interface Loopback6
no ip address
ipv6 address 2001:470:1F15:EB2::A/64
ipv6 enable

rtr-0#ping ipv6 2001:470:1f14:eb3::1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:470:1F14:EB3::1, timeout is 2 seconds:
Success rate is 0 percent (0/5)
rtr-0#ping ipv6 2001:470:20::2 source loopback 6

Any suggestions would be great since I'm stuck.
