Re: 6to4 tunnel trouble



Which network device is your ::2 end of the tunnel? In other words, do
you have a router that is connected to your modem and internet, or is
it solely a computer and a modem?

In the first case, make sure that your /64 subnet is routed back to
your LAN. As an example, this is the routing table on my WRT54GL with
DD-WRT:

---EXAMPLE---
~ # ip -6 r
<routed subnet>::/64 dev br0  metric 1024  mtu 1500 advmss 1440
default via <assigned ipv6 addr>::1 dev he-ipv6  metric 1024  mtu 1480
advmss 1420

~ # ip addr
8: vlan1:  mtu 1500 qdisc noqueue
    link/ether 00:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
    inet 94.x.x.x/21 brd 94.x.x.x scope global vlan1
15: he-ipv6@NONE:  mtu 1480 qdisc noqueue
    link/sit 94.x.x.x peer <IPV4 of PoP>
    inet6 2001:470:xxxx:xxxx::2/64 scope global
16: br0:  mtu 1500 qdisc noqueue
    link/ether 00:xx:xx:xx:xx:xx brd ff:ff:ff:ff:ff:ff
    inet 192.168.2.1/24 brd 192.168.2.255 scope global br0
    inet6 2001:470:xxxx:xxxx::/64 scope global
---/EXAMPLE---

Maybe you should try Looking Glass on tunnelbroker.net (since that
seems where your tunnel goes)

In the second case, you should provide your routing table (`ip -6 r`
OR `route -A inet6`) and the output of `ip addr` or `ifconfig`. When
you have iproute2 installed, use the `ip` commands.
