[Cerowrt-devel] IPv6 doesn't work quite right in 3.3.8-17 as 3.3.8-6

[Cerowrt-devel] IPv6 doesn't work quite right in 3.3.8-17 as 3.3.8-6

[Richard Brown]

I can't make IPv6 work in 3.3.8-17 using the same procedure as worked in 3.3.8-6. I am using the procedure and script listed in: http://www.bufferbloat.net/projects/cerowrt/wiki/IPv6_Tunnel

With 3.3.8-6, IPv6 starts right up and my MacBook can get an IPv6 address right away. Using 3.3.8-17, there is an error when running the script (see below), and after the restart, my MacBook won't get an IPv6 address. Notes: 
	a) the router itself has a v6 address, and can connect to v6-only resources (e.g., ping ipv6.google.com works)
	b) Immediately after running the script (and before rebooting 3.3.8-17), the MacBook may have received an IPv6 address

What other information could I provide to debug this? Thanks.

[Dave Taht]

It was my hope that the script would be unnecessary in this release,
that you'd be able to do a "adv_subnet" like in 6to4 and be in
business.

option 'adv_subnet' '1'
list 'adv_interface' 'se00'
list 'adv_interface' 'sw00'
etc

I'm not in a position to test hurricane from where I am right now.

Re: [Cerowrt-devel] IPv6 doesn't work quite right in 3.3.8-17 as 3.3.8-6

[Richard Brown]

Thanks for the speedy response. I can spend some time gathering data. 

I imagine that the script is still necessary for encapsulating the HE.net  credentials. (I guess I could do it from the GUI, but my fingers are really bad at doing the same thing twice...) 

After that, I'd do the option 'adv_subnet' '1' stuff. Is there a good writeup of what you wanted/would expect to work? Thanks.

Re: [Cerowrt-devel] UPDATE: IPv6 & 3.3.8-21 - working fine...

[Richard Brown]

Folks,

Here's an update on functioning of IPv6 in CeroWrt. I had posted a note in mid-August saying that I had troubles making IPv6 work properly in 3.3.8-17. Specifically, I was using the script from http://www.bufferbloat.net/projects/cerowrt/wiki/IPv6_Tunnel to configure IPv6 to work with Hurricane Electric's free Tunnelbroker.net service, and it not all interfaces got addresses as expected.

After a bit of testing, I am happy to say that the script on the IPv6 Tunnel page above seems to work properly on 3.3.8-21, the latest CeroWrt build. This script is substantially the same as earlier versions: I didn't have to tweak any radvd or other configs beyond what's in this script.

Best,

Rich Brown
Hanover, NH

PS I also posted a note about using mDNS/Bonjour on CeroWrt. By default, this works as desired on all the local interfaces; the note (http://www.bufferbloat.net/projects/cerowrt/wiki/Using_Bonjour_mDNS_or_ZeroConf_with_CeroWrt) gives instructions for passing the mDNS traffic out the WAN port, for instances where you are using CeroWrt as a secondary router in your home.

Re: [Cerowrt-devel] UPDATE: IPv6 & 3.3.8-21 - working fine...

[Sébastien Gaggini]

Hi,

Thanks for all the IPv6 links. I managed to make IPV6 work on my
network this morning after weeks of try.
First I had to add a proxy_ndp config ( ip -6 neigh add proxy  ....  )
for each of my host ( my ISP router need that ). It breaks all the
auto-configuration of IPv6 ...

Then I found this package in openwrt : ndppd
It does all the ndp proxy magic in background. So could you add it to
cero next build ? I

Thanks,
Sébastien
