Hey,
I'm on Mac OS X 10.6 Snow Leopard with the Cisco EPC2425 modem+router (my ISP insists on a combined one, and flashing with DD-WRT is a no no :().
I originally configured with these options:
ifconfig gif0 create
ifconfig gif0 tunnel MY.EXTERNAL.IPV4.ADDRESS 216.66.80.26
ifconfig gif0 inet6 2001:470:1f08:136b::2 2001:470:1f08:136b::1 prefixlen 128
route -n add -inet6 default 2001:470:1f08:136b::1
But got this error
bash-3.2# ping6 he.net
PING6(56=40+8+8 bytes) fe80::226:4aff:fe19:e8c%gif0 --> 2001:470:0:76::2
ping6: sendmsg: Can't assign requested address
ping6: wrote he.net 16 chars, ret=-1
Request timeout for icmp_seq=0
ping6: sendmsg: Can't assign requested address
ping6: wrote he.net 16 chars, ret=-1
I then decided to try using my internal DHCP server assigned IP with this line:
ifconfig gif0 tunnel 192.168.1.14 216.66.80.26
But got this slightly different error:
bash-3.2# ping6 he.net
PING6(56=40+8+8 bytes) fe80::226:4aff:fe19:e8c%gif0 --> 2001:470:0:76::2
Request timeout for icmp_seq=0
Request timeout for icmp_seq=1
Request timeout for icmp_seq=2
Anybody got any suggestions for me? I really like being slightly ahead in web technologies (let's lead by example ;)), so I'd love to set up an IPv6 tunnel.
Since you are behind nat, you need to use your 192.168.1.14 address to create the tunnel
Is your router passing protocol 41 traffic to your mac?
As you saw in my post, I did change the config to use my internal IP, but still got timeouts.
How can I check if my router is passing protocol41?
There isn't a way to test...you'll want to either turn off the firewall on your router to add your host to the DMZ of your router
Done both, still won't work :(
