Could you guys fix the routeloop in the SFBA? I'd like to keep using IPv6 at home without going back to the tunnel

I'm in Santa Clara, CA.

I'm using a Mikrotik Routerboard with 5.19 firmware. Modulo one aparent firmware bug (that has an easy workaround), I've successfully set up DHCPv6 PD for my home LAN.

Not only does it appear to be working correctly, I'm able to get almost 5 megaBYTES per second for the file transfers between my VPS in Texas and the machine in my house - the whole reason I really want to use IPv6 in the first place. Gigabytes of backup files in minutes. I'm astonished.

I'm not going to obscure the host part of the IP address in the screenshot... My mac picks a new host-part every few hours, and I have an IPv6 firewall set up.

[Jim721]

Still says it prefers v4 over v6,, This is what you want to see,

[Murphy]

That's because he is using Safari.

apple still hasn't configured Safari to prefer IPv6.

[nsayer]

It's more complicated than that. MacOS X actually does a probe to see which one is faster and then sorts the connection attempt order that way. When using ssh to get to my VPS, sometimes I get IPv6, sometimes I get IPv4.

3) {{not applicable}}

router acquires the 2001:558:6045:*/128 for the WAN side and configures the LAN side as 2601:9:200:2d:*/64 and adds a couple v6 nameservers through wide-dhcpv6-client.  using NA option and setting sla_len to zero as you are only delegating us a /64.

But I have no route when executed on the router:

root@OpenWrt:/# ping6 comcast6.net
PING comcast6.net (2001:558:fe16:7:69:252:216:215): 56 data bytes
ping6: sendto: Network is unreachable

Is my head-end 1/2 enabled?

If I add a default route with 'ip -6 route add ::/0 dev eth0.1', ping6 is silent instead of coming back with an error.  I've checked and made sure accept_ra is set on the WAN interface.  This was working before using he.net's tunnel service prior.

Windows 7 64-bit, wired to Netgear WNR1000v2 router

 

[EG]

Have you gotten the new new firmware for this router that now has IPv6 support ?

[live4nhl77]

I tried updating the firmware to what I would assume is the newer version, but it keeps saying it failed. I looked up online all the troubleshooting tips, but still won't update. It keeps saying that my firmware is up to date.

[EG]

FWIW, the new version of firmware is 1.2.2.56NA. Look under the "Router Status" tab for the version that is currently loaded. Are you trying to get it using the router's built in upgrade utility ?

[live4nhl77]

Yes. I am using the router's upgrade function. the firmware version that I have now is 1.0.0.12NA.

[EG]

For a manual download and install, get it here;

http://kb.netgear.com/app/answers/detail/a_id/20757

Follow instructions.

[live4nhl77]

I upgraded the firmware to the one you sent me the link to. Everything went well. But in the LAN status it is still showing as "no internet access" for ipv6.

[EG]

Then you may be on a CMTS / system that does not have native IPv6 enabled yet. Try sending a private message to the author of this thread (Comcast Tuska) asking about it here;

http://forums.comcast.com/t5/notes/privatenotespage/tab/compose/note-to-user-id/4903361

He can check the local system for you.

[kevj]

For those with Netgear routers...if you have confirmed that your CMTS is IPv6 capable (PM ComcastTuska), try the procedure inthe link below...it may not be a blanket fix, but I found that it works on my WNDR3700 v1 WITH THE INDICATED FIRMWARE!!!. It may be applicable only to older models where Netgear have had to update the firmware to provide IPv6 compatibility, and it may NOT work at all...

http://www.dslreports.com/forum/r27214510-

Unfortunately, if this DOES work, you may have to go through this procedure every time you have a power outage to your router. Apparently the IPv6 configuration on the WAN interface (at least on the router/firmware version I am using) likes to have some delay to enable the IPv6 connectivity to work properly.

Attn: ComcastTuska: care to explain how to attach a screenshot to satisfy your request?

I think that as a first time poster attaching images or links is disabled.

Based on other forums you probably need at least 5 previous posts before you can post links or images.

Goto ASUS website and download the latest code. Once you set the device to "DHCP-PD", reset the device.  It requires a reboot after you set it to IPv6 PD.

Great thanks, I had the latest firmware, but it was the manual router re-boot that fixed it:

Contact Comcast Larry about it via a PM Jim. It may be just for newer posters that only have a small amount of posts here so far.

dskrabal,

If memory serves, your area is on a Cisco CMTS which does not have IPv6 deployed yet (Tuska may confirm either way). The IPv6 address you are seeing on your Win 7 box id a 6to4 tunnel address, not a native IPv6 address...
