I am a home user. My provider, Cox, supports IPv6. Installing IPv6 on my Xp platform works great plugged directly into the cable modem..

Following the various examples on how to configure IPv6 in dd-wrt and doing the things suggested to make V24 work I still cant get it...

Im running Mega, I have lots of jffs avaliable.
DD-WRT v24-sp2 (03/27/09) mega - build 11793M NEWD Eko

Im mostly default settings...

Can someone please give me some help. Maybe some config for Radvd and startup scripts to get this to work please

Again I can hook the computer directly to the cable modem and do ping6 and resolve/use IPv6 like ipv6.google.com. But adding in the router and it no longer works with any suggested script/config i have found.

[Xymox]

I resolve the IPv6 addresses fine but cannot connect to them...

Ping6 ipv6.google.com

Pinging ipv6.l.google.com [2001:4860:b002::68]
from fe80::f200:8dff:fed1:783f%7 with 32 bytes of data:

Reply from fe80::f200:8dff:fed1:783f%7: Destination unreachable

This seems wrong cuz it looks like it trying to ping my local address ?? I donno... IPv6 seems way more complex then IPv4

[Xymox]

hooking my computer directly to the cable modem and doing a ipconfig /all it looks like it uses
"Tunneling adapter 6to4 tunneling psuedo-adapter"

This gets a IPv6 gateway and IP...

My ping6 to google does seem right showing a 2001: address rather then when im connected to the router which then returns a fe80: when i do the same command.

Is it just that V24 is still busted for doing IPv6 ?

With the new pressure to do IPv6 its really kinda a requirement for all of us to get on with it and do IPv6.

Windows in many flavors supports it, so do most other OS'. ISP's are adopting it quickly, or at least supporting tunneling.

In fact the weak link are home routers.

I think DD-WRT really needs to fully support IPv6. Statefull inspection firewall, DHCPv6, IP6to4 and all the other options.

Soon we may start to see web sites that only exist on IPv6.

If you want to know if you can do IPv6

go here, click on IPv6 only test.

[Xymox]

I think this is a good standard suite of tests DD-WRT should be able to pass..

does anyone have IPv6 working on V24 ?

If so how, what scripts ?

My cable co supports it..

[Xymox]

Well I have played around alot... Rewad a lot of threads....

IPv6 just does not work on Mega 11793M NEWD Eko

Can someone offer any suggestions ?

Is this being worked on ?

I can get Radrd started manually and configured..
I can load manually the IPv6 module

I have tried many scripts and configs on this forum.

The IPv6 iptables are beyond me..

This really needs to be addressed... IPv6 is seriously broken.. This is kinda embarrassing for such a cool, sophisticated and well developed product.

Mega should absolutely have full working IPv6 support that does not require command line, scripts and configs.

Try 11296. Note that these are test builds, and they are still working on them. Don't expect them to be fully functional or working perfectly. If they were, they would be SP2, not pre-sp2.

Might also try 12030, but I don't think I saw any IPv6 comments in trac.

[Xymox]

I like having NAS, so I dont want to go back in versions.

I loaded 12031M NEWD Eko

Enabeling IPv6 support on the GUI still does not load the module ( lsmod - no IPv6 ) and I still dont see Radvd in a ps...

So even with a build done on 4/30/09 it does not work at all from the GUI.

[theermine]

I tried following every tutorial I could find on setting up IPv6 a couple months back to no avail.. I finally gave up on it. I'd love to see the solution if one ever comes to be though!

[barryware]

Make sure you guys file a bug report in trac. If you don't, you can't be sure that the devs will see this thread.

Hi,
Xymox, I am using IPv6 without any problems.
Current version dd-wrt.v24-12031_VINT_mega.
To load radvd you need to radvd -C /tmp/radvd.conf start (but it is included in the command script below).
Also make sure where is your IPv6 module, mine in VINT ver is in /lib/modules/2.4.35/ipv6.o (in NEWD it is in different location)
I use tun6to4, and following scripts:
Radvd config

interface br0 {
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
AdvLinkMTU 1280;
AdvSendAdvert on;
prefix 0:0:0:1::/64 {
AdvOnLink on;
AdvAutonomous on;
AdvValidLifetime 86400;
AdvPreferredLifetime 86400;
Base6to4Interface vlan1;
};
};

Commands:

#insmod /lib/modules/2.4.36/ipv6.o
insmod /lib/modules/2.4.35/ipv6.o
sleep 5
radvd -C /tmp/radvd.conf start
sleep 5
WANIP=$(ip -4 addr show dev vlan1 | grep 'inet ' | awk '{print $2}' | cut -d/ -f1)
if [ -n "$WANIP" ]
then
V6PREFIX=$(printf '2002:%02x%02x:%02x%02x' $(echo $WANIP | tr . ' '))
ip tunnel add tun6to4 mode sit ttl 255 remote any local $WANIP
ip link set tun6to4 mtu 1280
ip link set tun6to4 up
ip addr add $V6PREFIX:0::1/16 dev tun6to4
ip addr add $V6PREFIX:1::1/64 dev br0
ip -6 route add 2000::/3 via ::192.88.99.1 dev tun6to4
kill -HUP $(cat /var/run/radvd.pid)
fi

And again, it works great for me.
Good Luck

OoOoOoo

thank you Pandora.. I will have to go try this...

Where do I open a ticket ? In the bug tracker ?

[Xymox]

W O W...

Ok I got some strange stuff to report...

First doing the above to the router. Power cycling the router to do full reset..

Reboot the computer ( win XP + IPv6 ). No firewall other then the one in XP.

Go to http://ipv6.whatismyv6.com/

No go...

Initial IPconfig shows i get a v6 IP and a v6 gateway but nothing IPv6 pings. See attached initial.gif

Hook the computer directly to cable modem and reset network adapter.

I now get some sort of 6to4 tunnel in windows.
See attached cabledirect.gif

Hook the computer back to the router and reset the adapter. See attached backtowrt.gif

IT WORKS !..... Hmmmmm.......

Maybe the computer is getting something from the cable modem direct connection that lingers past the network reset ?

Reboot computer...

It still works !

Reboot router,,,, no longer works...

If I then connect the computer again it will work until I reboot the router...


SOoOOOoOo.....

It seems my connecting the XP computer directly to the cable modem is gaining some information in the direct connection with the cable modem that gets shared with the router once I connect it back to the router.

Thats very very weird...

Its completely repeatable...

The computer is doing DHCP.

Reboot router, reboot computer - no IPv6 pings
connect computer to cable modem - pings
connect computer to router - pings
reboot computer - pings
reboot router - no more ping

There is something that the router is not passing along to the computer, or not getting from the modem, that somehow the computer gets and passes back to the router when connected to the lan side.
