Title: I could use some help sorting things out configuring my tunnel [OS X]
Post by: sweex on December 23, 2010, 09:55:05 AM
I configured my tunnel with hurricane and then I tried to configure the tunnel.
I'm behind a NAT so I entered the IP that I got from my router (192.168.1.16 in this case)
But when I try to ping ipv6.google.com for example I only get time-outs.
But what looks a bit strange to me too is the IP from which it pings, it isn't the same as Hurricane's IPv6 address or the one I got assigned.

sh-3.2# ping6 ipv6.google.com
PING6(56=40+8+8 bytes) ::6233:4bff:fe0e:421 --> 2a00:1450:8006::93

What did I do wrong in my configuration?

I don't know

How did you set it up? What commands did you issue?

What do your routing tables look like?

What does ifconfig show?

well it looks like it's working now... I don't have a clue about what changed, but it works now so thank you for the intention to help me ;-)

I have the same situation.  Ubuntu router,  with desktop behind it.  Router can hit ipv6.google.com, and the desktop cannot.

i used the instruction on tunnelbroker to create sit0 and sit1.
Here's what the site gives me to enter:

in have sysctl.conf I have uncommented:
net.ipv6.conf.all.forwarding=1

Ipv4 forwarding works fine, so I'm assuming I have a problem in ipv6 forwarding somewhere.  Do i need to set a msquarade or is the an iptables?  i have ipv4 masquerading set, using UFW: before.rules

*nat
:POSTROUTING ACCEPT [0:0]

# Forward traffic from eth1 through eth0.
-A POSTROUTING -s 10.99.99.0/24 -o eth0 -j MASQUERADE

on the router, did you add 2001:470:1f05:173a::1/64 to the LAN facing NIC?
Title: Re: I could use some help sorting things out configuring my tunnel [OS X]
Post by: cholzhauer on January 13, 2011, 05:11:09 AM
I'd have to agree...you need to assign an address to eth1 on your router.

Added the ip6 addresss to eth1, that seems to have resolved it.  Thank you.
