Folks, I've read through the docs and forums on the OpenWrt site, and haven't found a good answer. I'm using a new/clean install of CeroWrt 3.3.6-2 on a WNDR3700v2, which I believe should work exactly the same as OpenWrt.
I am having trouble making my Hurricane Electric 6in4 tunnel work with CeroWrt. I have created the script below that uses the suggested configurations from tunnelbroker.net to set up the tunnel. (This is substantially the same script as posted to: http://www.bufferbloat.net/projects/cerowrt/wiki/IPv6_Tunnel ) Here's what I see: a) The script below uses the tunnel's Client IPv6 /64 address, and does establish the tunnel. If I ssh to the router, I can ping ipv6 hosts from the router, traceroute to ipv6 addresses, etc. However, my MacBook on sw10, for example, does not get a global IPv6 address. b) I also used tunnelbroker.net to obtain a routed /48 address. I use the LuCI GUI to set an IPv6 address for the interface from that /48 subnet. For example, if the routed /48 is 2001:470:ABCD::/48, I have assigned the IPv6 address of sw10 (one of the wireless interfaces) to 2001:470:ABCD:902::/64. My Macbook gets the global address 2001:0470:ABCD:0902:0221:e9ff:fee3:d4b0/64, and I can ping IPv6 addresses. But... c) I cannot reliably connect to certain hosts, even IPv4 hosts such as tunnelbroker.net. When I traceroute6 from my Macbook, I get: % traceroute6 ipv6.google.com traceroute6 to ipv6.l.google.com (2607:f8b0:4004:803::1010) from 2001:470:ABCD:902:221:e9ff:fee3:d4b0, 64 hops max, 12 byte packets 1 2001:470:ABCD:902:: 4.622 ms 108.652 ms * 2 2001:470:ABCD:902:: 2.704 ms 6.961 ms 17.329 ms % What am I missing? If I can get some help here, I'll write this up and post it to the CeroWrt wiki. Many thanks!
