ip6tables -I INPUT -d 2001:470:1f15:153::99 --dport 80,23 -j DROP


Except by doing that, we won't be able to access the router either! How are you going to configure it from there on? :/

Here's a better idea, let's ACCEPT the computers on our subnet, and reject everyone else. I believe that's more functional.

Anyway, here's how i'm doing it

Code:

insmod ip6t_REJECT

#First, let's accept ourself
ip6tables -A INPUT -s 2001:XXXX:XXXX::0/64 -d 2001:XXXX:XXXX::1 -p tcp -m multiport --dports 22,80 -j ACCEPT
#Now tell everyone not in our tea party to sod off
ip6tables -A INPUT -d 2001:XXXX:XXXX::1 -p tcp -m multiport --dports 22,80 -j DROP
#Same for the tunnel back-door
ip6tables -A INPUT -d 2001:YYYY:YYYY::2 -p tcp -m multiport --dports 80 -j DROP


Where the XXXX:XXXX parts are your /64 (or /48 if you use SIXXS) subnet and YYYY:YYYY is your tunnel. Oh, and the ::1 is your routers subnet v6 ip (yes, old habits DO die hard, but they feel so right Wink )

On a completely unrelated note, could somebody PLEASE pick this one up and update it? I mailed the original dev, hope to hear from him, but i'm afraid he's already moved on. I would even donate to the cause. There's not much to be done anyway. For starters the upnp daemon is dead in 10070. Mighty usefull for torrent clients and other stuff. Next thing would be SD mod (it's supposedly not in this build). And thats the end of my wishlist.

I'm running ASUS WL-520Gu with crushedhat's firmware. Works great, and I do appreciate the hard work and effort you've put into it. I only have one complaint.

I'm losing time! I also read about it in

Is there an easy fix?

So I setup a cron job:

5 0,4,8,12,16,20 * * * /usr/sbin/ntpclient time-a.nist.gov

Should that be sufficient? Or do you think that'd be hammering the server?

I'm running http://www.crushedhat.com/downloads/DD-WRT/dd-wrt.v24-10070_crushedhat_4MB.bin and every IPv6 device on my LAN has an IPv6 that is pingable from my he.net tunnel. Smile

Folks,

I am using DD-WRT so that I can properly manage VOIP traffic on a WRT54GL. Now that I have WIN7 I would like IPV6 to work.

Before I flash his firmware, can anyone answer these questions for me?

1) Does crushedhats build support VOIP QoS?
2) Does the build assign IPv6 addresses to both LAN and Wireless clients?

Thanks in advance!

I do not remember seeing a build that supports VOIP and IPv6. I think the size starts to get up there.

I would say if you have a necessary service, do not install dd-wrt on it now. dd-wrt will work, but it may take you a bit to get it all sorted out.

I am already using build 12533 with success, but my new win7 laptop keeps dropping wireless connection (no problem with linux or xp). I suspect this is because of IPv6 not working on v24. If crushedhats QoS options include VOIP support (like build 12533) then I am good to go. Actually I am using the port precedence in the QoS panel anyway to prioritize traffic from the phone. If he has at least that, then I will upload it & re-configure.

After reading this entire thread and following all the links, am I to correctly assume that there is no way to enable IPv6 functions on my WRT54G v6 (running v24-sp2 build 13064 micro generic)? My first clue is that there is no check box on the Administration>Management page to enable/disable IPv6. All of the other builds seem to be for 4 MB flash - is there no way to make it work on a 2 MB flash unit? Thanks for your help!

Is anyone having success with the newer builds? With 13972 std-nokaid I can establish my tunnel to sixxs and ping my router from "outside" but the ipv6 routing to my networked PCs seems to be broken ... they get valid ipv6 addresses from radvd but that's it.

Help appreciated.

Regards,
SMF

Official micro builds do not include IPv6 support. More specifics here: http://www.dd-wrt.com/wiki/index.php/What_is_DD-WRT%3F#Build_Features

Found I can route from the tunnel with just the following:

ip tunnel add he-ipv6 mode sit remote 66.220.18.42 local 24.251.38.95 ttl 64
ip link set he-ipv6 up
ip addr add 2001:470:c:1c1::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6

interface br0
{
AdvSendAdvert on;
MinRtrAdvInterval 3;
MaxRtrAdvInterval 10;
prefix 2001:470:d:1c1::/64
{
AdvOnLink on;
AdvAutonomous on;
AdvRouterAddr on;
};
};


To route from a linux machine behind the router I need the following:

ip addr add 2001:470:d:1c1::1/64 dev br0
[Routed 64 IP assigned to 192.168.1.1]

Sometimes I need to ping 2001:470:d:1c1::1 from a lan machine to pick the route backup to ping the outside world.

Then it drops again, any ideas?

Just a tiny update for anyone else who runs into the issue with crushedhats build.

IPKG not working, ammaright?

cd /jffs/usr/lib/ipkg/lists/
wget http://downloads.openwrt.org/whiterussian/packages/Packages
mv Packages whiterussian
ipkg update

ipkg is now fixed.
