IPv6 Support

[lly]

Just curious, what impact, if any, do the latest changes to the firmware

have on the issues we discussed above?

Please, read the news carefully - changes you mentioned, relates to 1.9.2.7-rtn branch which is kernel 2.6.22 based.

My apologies, I stupidly missed the large bold characters at the top

May I ask, will there be much work relating to ipv6 on the 'd' builds?

Thanks.

Not planned. Backport of IPv6 stack & netfilter features really huge task and, since all modern devices supports 2.6, has zero priority. Anyway, if someone will contribute some patches, we gladly accept it.

Ok lly, thanks I guess it's time to try the rtn build...

I can't believe this!

I've just upgraded to 1.9.2.7-rtn-r2775 and all the problems I was experiencing before have returned, can't connect to various ipv6 sites, score 1 out of 10 on test-ipv6 etc.

The tunnel is correctly configured and I can ping -6 all over the place. I can also connect to some ipv6 sites like ipv6.google.com. I've tried this from two different PCs and the results are the same.

Could these problems have anything to do with the way I connect to the Internet, it's Russian Dual Access, with an l2tp tunnel through the ISP LAN to the Internet gateway?

Edit: Out of curiosity, I put SUSE 11.4 on a box and it had the same problems, so whatever the issue is, it's platform independent

Dapper, that is possible yes.
When I upgraded my WL500W to the rt-n firmware I noticed some settings couldn't be found.
There is a good chance you might need to reconfigure your router for the rt-n firmware, or at least try to restore the settings

[Dapper]

I give up!

1. Fresh installation of Windows 7 (nothing else added)
2. Reset router to factory defaults
3. Configured router for IPv6
4. Enabled ping
5. Configured the tunnel
6. Confirmed connectivity with ping and tracert
7. Tried to browse to ipv6 enabled sites such as tunnelbroker.net - Failed
8. Tried test-ipv6 - 1 out or 10

There has to be something obvious I'm missing with the router, because if I remove it from the equation and end the tunnel at a PC, it works. Likewise, if I disable ipv6 on the adapter so I'm connecting with ipv4, it works.

[Dapper]

For what it's worth, the problem I'm having is the same as the one reported here: http://code.google.com/p/wl500g/issues/detail?id=198 As mentioned above, I too am using l2tp.

I have no idea what the OP did to 'fix' his problem, it would seem a custom compile...

I seem to have found a temporary solution by modifying the ipv6 MTU via netsh:

netsh interface ipv6 set subinterface "name of adapter" mtu=1280

Doing so gives me 10 out of 10 on test-ipv6 and sites load as quickly as they do with ipv4 alone.

However, I don't really understand why I should need to do this only when the router is terminating the tunnel. It seems to suggest PMTU is breaking down somewhere?

[outlaw11]

I added documentation on how to configure a tunnel due to the amount of problems and questions
http://code.google.com/p/wl500g/wiki...Pv6Tunnelhowto
Obviously things still could go wrong, but this makes things easier

Also added the link in the first post of this thread

Page "GUIIPconfigIPv6Tunnelhowto" Not Found

Can you repost pls?

[wpte]

Can you repost pls?

ah excuse me, the file name has changed, but it can still be found in the wiki menu
anyway, direct link: http://code.google.com/p/wl500g/wiki...gIPv6HowTo6in4
And I'll edit my post

[outlaw11]

thank you

can you suggest some good or prefered iptables rules with ipv6 tunnel?

The main IPv6 firewall is active by default when the main firewall is turned on, so you shouldn't need extra configuration

but you should be able to add some extra things, like opening up port 80 for your router:

#Remove last drop
ip6tables -D INPUT -j DROP
#add extra rules
ip6tables -A INPUT -p tcp --dport 80 -j ACCEPT
#add the final drop again
ip6tables -A INPUT -j DROP

[theMIROn]

this way is more secure and convenient, imho:

# set default input rule
iptables -P INPUT DROP
ip6tables -P INPUT DROP
# remove last default rule
iptables -D INPUT -j DROP
ip6tables -D INPUT -j DROP
# allow ...
iptables -A INPUT ... -j ACCEPT
ip6tables -A INPUT ... -j ACCEPT
# allow ...
iptables -A INPUT ... -j ACCEPT
ip6tables -A INPUT ... -j ACCEPT

[wpte]

True, if "ip6tables -A INPUT -j DROP" for some reason doesn't execute correctly
Or if you don't have a default firewall running

it works either way

My ISP has started rolling IPv6 and offers native IPv6 dual-stacked with IPv4. The requirements are as follows: the router should support PPPoE Ipv6 and Prefix Delegation via DHCPv6. Also, I have to write "ipv6" in the Service Name box. I currently connect via PPPoE, using an Asus WL500gP v1 with DD-WRT, which apparently doesn't support the reqs. above.
I'd like to try Oleg's, but before I start flashing again, can anyone tell me if those 2 features are supported by Oleg's firmware?

• PPPoE Ipv6
• Prefix Delegation via DHCPv6
