Re: Recieving /128 Address (OpenWRT)

said by GmDude66:

Have not found any results. Thinking about switching back to DD-WRT :P

Sorry that I took so long to get back to you, but my notebook was in use by someone else, and that is the only reasonably convenient box I have to access my Netgear guest router.

Once I had it connected, I found that there was no clearly defined config for ICMP6 except for the ip6table rules.

Just for grins, I did an "ip6tables -F" command in the router which cleared the ipv6 firewall rules. That effectively killed LAN to WAN IPv6 traffic in that router. I then did the traceroute below from the notebook:





As you can see, I was no longer able to do a traceroute to an IPv6 server on the Internet, but my Netgear router still responded to the traceroute ICMP6 echo request on its LAN. Since your router did not respond to the ICMP6 echo request, that would seem to indicate that your problem is not necessarily related to a lack of ICMP6 rules. However, you could do a "ip6tables -L" command in your router to see what rules (if any) are present. Here is what I saw after I flushed the ip6tables in my router:





If you don't have any ip6tables rules in your router, that would definitely be a problem, but that may or may not be the only problem. FWIW, here are the ip6tables that are normally in my router:





If you would like to see any specific config or script file on my router, let me know and I will try to find it and post it. I say "try" because even though the router does run on OpenWrt, it is still a Netgear specific version of OpenWrt, and they seem to be doing some rather obfuscated things. Most of the config files that I see are created on the fly by script files on bootup, so I don't see the usual generic config files that are present in public OpenWrt distributions.

I am thinking this is a firewall issue.

Can you please look over this config?

If there is anything in the ip6tables information that you posted that would keep your router from processing LAN to WAN IPv6 traffic, I don't see it; but perhaps someone with a keener eye (and more IPv6 experience)* will look at it and let you know definitively.

*When I was actively providing network support before my retirement last year, I did not get involved with native IPv6 support because none of the ISPs I worked with offered it (and I did not even have any clients who needed/used IPv6 tunnels). I have therefore only been involved with my own IPv6 connections, and I have had to learn what I know about IPv6 the hard way.
