Introduction
There are too many devices in the world for 32-bit (232, or 4,294,967,296) IP addresses to be sufficient. The next version of the TCP/IP protocol, IPv6 offers 128-bit address space, or 2128 (≈ 3.4 x 1038) IP addresses.
IPv6 is supported since DD-WRTv22 prefinal5.
Prerequisits
- Knowledge about the Command Line
- Knowledge about the ip command
- 24/7 Internet Connection (dynamic dialup is ok)
- Enabled jffs would be helpful
- Enable IPv6 at your routers webinterface
Setup
SixXS Tunnel Broker
Requesting a Tunnel/Subnet
1. Create a 6bone handle at http://www.sixxs.net/signup/6bone/. (Skip this if you already have a NIC handle.)
2. Sign up at http://www.sixxs.net/signup/ with your create handle. (Or use your existing one.)
3. After your login at http://www.sixxs.net/home/ you can request a tunnel and later a subnet.
Static Tunnel
The sconk.se guide offers some pretty nice instructions on how enable this feature starting out with obtaining an IPv6 address.
This wiki also offers an example IPv6 startup script

Dynamic Tunnel
Install AICCU
1. Install AICCU using ipkg.
# ipkg update # ipkg install aiccu
2. Configure AICCU.
# vi /jffs/etc/aiccu.conf
# AICCU Configuration # Login information username <your nichandle/username> password <your password> # Interface names to use ipv4_interface vlan1 ipv6_interface sixxs # The tunnel_id to use # (only required when there are multiple tunnels in the list) tunnel_id <your tunnel id> # Be verbose? verbose false # Daemonize? daemonize true # Automatic? automatic true
Automatic start your Tunnel
1. Create a .startup file and make it executable.
# vi /jffs/etc/config/aiccu.startup
#!/bin/sh /jffs/etc/init.d/S51aiccu start ip -6 addr add 2001:xxxx:xxx::/64 dev br0 # Edit to your assigned subnet settings. (You have to use /64 here)
# chmod +x /jffs/etc/config/aiccu.startup
2. Adjust the AICCU init script.
# vi /jffs/etc/init.d/S51aiccu
#!/bin/sh case "$1" in start) ( while [ `date +%Y` -eq 1970 ]; do sleep 1 done && /jffs/usr/sbin/aiccu start /jffs/etc/aiccu.conf ) & ;; stop) aiccu stop /jffs/etc/aiccu.conf aiccu stop /jffs/etc/aiccu.conf ;; restart) $0 stop $0 start ;; *) echo "Usage: $0 {start|stop|restart}" exit 1 ;; esac
Announce your Subnet with radvd
1. Enable radvd at the webinterface of your router (Administration->Management->IPv6 Support)2. Insert your radvd.conf into the form and save your settings. (You have use the /64 prefix even if you got a /48 subnet) interface br0 { AdvSendAdvert on; prefix 2001:xxxx:xxxx::/64 { AdvOnLink on; AdvAutonomous on; AdvRouterAddr on; }; };
Hurricane Electric's Tunnel Broker
If you want to use Hurricane Electric's IPv6 Tunnel broker you can check out this guide. It has detailed instructions and is upto date. Sixx.net takes alot of work and requires you to sign up to alot more stuff then Hurricane Electric.

Notes
Static IPv6 at WinXP
If you want to disable temporary IPv6 addresses at your WinXP try:
cmd> ipv6 -p gpu UseTemporaryAddresses no
ping6 at dd-wrt v23
Try to install busybox from OpenWRT: http://downloads.openwrt.org/people/nico/testing/mipsel/packages/busybox_1.01-1_mipsel.content
~ # ipkg install http://downloads.openwrt.org/people/nico/testing/mipsel/packages/busybox_1.01-1_mipsel.ipk
Okay now you have to install uclibc (with -force-depends): http://downloads.openwrt.org/people/nico/testing/mipsel/packages/uclibc_0.9.27-6_mipsel.content
~ # ipkg -force-depends install http://downloads.openwrt.org/people/nico/testing/mipsel/packages/uclibc_0.9.27-6_mipsel.ipk
After installing these packages you have to change the priority of the /lib path in your shell environment:
~ # export LD_LIBRARY_PATH=/usr/lib:/jffs/lib:/jffs/usr/lib:/jffs/usr/local/lib:/lib
Now ping6 should work for the current xterm session.
