My improvements are:
* Can be used even if you haven't yet earned enough credits for a /48 subnet yet (the routing tunnel needs to be up for 7 days before you earn enough credits to get a /48, which can then be used for hosts on the LAN).
* If MTU setting is not optimal, will output a message with the correct value to use.
* Will determine the correct device (ppp0 or vlan1) depending on whether you use PPPoE to connect to your ISP.
* Additional fixed IP addresses can be added for the router should you desire.
* Logs progress messages to syslog as well as console.
* More comments detailing setup, for easier use.

Does anyone have any objections if I post this new version on the Wiki in place of the old one?
I've been using it myself for a week or two with no problems on v23 SP2 (the method is pretty much identical to the old script), but any feedback from anyone else's testing would be welcome.
I use a similar (but much simpler)script with success - at least it works to give an IPv6 address to windows XP and Vista computers but does not work with OS X (Leopard or Tiger). Do you use Windows, OS X (or Linux - which I have not tried) and would you have any idea why OS X isn't picking up an IPv6 address from the router? My router is obviously set correctly since I get an IPv6 address in Windows but I'm curious why it doesn't work in OS X.

I use Linux, and also occasionally Windows; both work fine. I'd agree your router is set up correctly, so the problem lies in your OS X configuration somewhere. You should probably read up some more on IPv6 in OS X, or try an OS X forum.
I'm new to dd-wrt but already have a sixxs tunnel incl. /48 subnet.
I was wondering if i needed both scripts, this one and radvd example or would radvd only be enough ?
:update:
After reading the help in the script i'm not sure what to enter in this par":
Quote:
# A /64 from your /48 subnet prefix assigned by SixXS, INCLUDING the /64
## This should match what you announce to the network with radvd (set in Administration -> Management in the web interface)

###SUBNET="2001:db8:2222::/64"
After reading complete file i'm wondering where my /48 subnet goes ?
Sorry to post in an 9 month old topic, but it was linked from the Wiki.
At the moment I use aiccu on my main PC to create the 6to4 tunnel, with username, password, tunnel-id, ...
Looking at this script, it creates the tunnel without these information.
Is this correct that they are not needed to establish the Sixxs 6to4 tunnel?

This script is not for using AICCU, or AYIYA, it is for a static tunnel with SiXXs... and to user gloomytrousers, I thank you for being so thorough in the documentation in the script... it made much more sense, and I was able to get the actual tunnel up in one shot!!! now if I can figure out the HE tunnel, I will have both the routers up and running... (already have my subnet there)

the script, and RADVD are separate... the script is for setting up the actual tunnel, RADVD acts "Kinda" like a DHCP server, saying "Hey Guys, this is the important part of the IPv6 address, you can fill in the rest based on other info you already have"

I think that you "Probably" would start off with the first IP set... with /64, then perhaps test to make sure everything was working for you, and then after testing, then where you have it saying /64, change that to /48
kind of like with IPv4, using /30 (255.255.255.252)4 hosts {one network, one gateway, one host, one broadcast) and then opening up to a larger subnet. a /48 is truly a mind boggling thing when you consider it... as is a /64, like 18 million IP addresses?
I'm having a trouble not finding my own external ip on this script (173.60.52.122) can I just add it manually in here? can someone please show me how a sI am tottaly lost

Posted: Wed Nov 28, 2012 21:29 Post subject: No such device
Hi,
At the Sixss portal I changed the aiccu tunnel to a static one. I'm running the script on the commandline, the script wasn't able to detect the WAN ip, so I added it manually aswell.
When I now run the script it say's :
sixxs: Starting IPv6 setup
sixxs: - Creating SixXS tunnel x.x.x.x <--> 192.87.102.107
ioctl: No such device
sixxs: - Bringing sixxs device up

sixxs: - Fixing MTU and TTL of sixxs device
SIOCSIFMTU: No such device

sixxs: - Adding default route through SixXS 2001:610:x::1

I'm using DD-WRT on a Netgear WNDR3700 router v1 with DD-WRT v24-sp2 (03/19/12) std - build 18777. Should it be able to work on this router ?
aiccu works better than static tunnel, and being offline (unpingable) does not cost you credits. _________________ 2 times APU2 Opnsense 21.1 with Sensei
2 times RT-AC56U running DD-WRT 45493 (one as Gateway, the other as AP, both bridged with LAN cable)
3 times Asus RT-N16 shelved
E4200 V1 running freshtomato 2020.8 (bridged with LAN cable)
3 times Linksys WRT610N V2 converted to E3000 and 1 original E3000 running freshtomato 2020.8 (bridged with LAN cable)
I have it working now, and copied the sixxs.sh script to /jffs for permanent storage.
I have 3 questions regarding this:
- How can I start this script at boot? I don't see something like rc.local or something.
- My subnet from SixXS is converted from aiccu to static, before the change it was up for 6 months, do I have to wait a week for the subnet to become active still?
- I used the radvd conf with the subnet I gained from sixxs, and I see that my Windows and Mac devices are getting ipv6 addresses, but they won't ping or connect using v6 at all, Windows even states that internet access is not possible with ipv6 with the addresses given, any thoughts?
