FAQ : Connectivity (Tunnels and Subnets) : How do I configure my machine to setup the IPv6 in IPv4 tunnel to the SixXS PoP?

Can I move my tunnel/subnet to another PoP? Can I request multiple subnets over my tunnel? Can I use SixXS tunnels to hide my IPv4 IP? Can a heartbeat tunnel be converted to a static or AYIYA tunnel or vice versa? Do you provide 6to4 connectivity? Do you provide BGP peering? Heartbeat or AYIYA tunnel doesn't work How do I configure my machine to setup the IPv6 in IPv4 tunnel to the SixXS PoP? How do I give connectivity to other hosts on my subnet? How is my endpoint connectivity tested? I have a firewall, what ports/protocols are used? IPv6 Transition Mechanism / Tunneling Comparison Is my connectivity filtered? / Mandatory IPv6 Filtering on IPv6 Is there a command line/non web tool for SixXS? Is there a traffic/data limit? Is there support for dynamic IPv4 endpoints? Multicast Support My IPv6 is random and changes often. Why? My static endpoint is broken and I don't want to lose credits My tunnel doesn't work My tunnel goes down after some idletime. My tunnelendpoint also is a NAT/Connection Tracker My tunnel/subnet doesn't work at once My tunnel/subnet stays in deleted state PoPs that are marked down The tunnel is slow Transit / I have some other tunnels and now it doesn't work Tunnel endpoint didn't ping What is the MTU of a tunnel? Where can I get native IPv6 / Which ISPs provide IPv6? Where can I get native IPv6 transit? Which PoP should I choose? Why are some PoPs not available for tunnels

How do I configure my machine to setup the IPv6 in IPv4 tunnel to the SixXS PoP?

The easiest way is by using AICCU, though if one wants to configure it manually or because AICCU doesn't support your platform, then you can pick your Operating system from the following list. AICCU can configure static, heartbeat and AYIYA tunnels.

The manual methods described below only apply to static proto-41 tunnels. AYIYA and heartbeat tunnels require AICCU.

A great resource for configuring Linux with IPv6 can be found at Peter Bieringer / LinuxDoc.org.

This small FAQ item describes the 'ip' way of setting up IPv6 on Linux. You can find it on ftp.inr.ac.ru, or in any modern linux distribution)

First of all, retrieve and compile a current 2.2 or 2.4 kernel. And get glibc2.1.3 (older versions have several bugs in them, regarding IPv6)

You'll have to recompile your kernel with the following options.
# cd /usr/src/linux
# make menuconfig

go to networking options, select the following:
[*] Kernel/User netlink socket
<*>  Netlink device emulation

<*>  The IPv6 protocol (EXPERIMENTAL)
  [*]   IPv6: enable EUI-64 token format
  [*]   IPv6: disable provider based addresses

# make dep;make clean;make bzImage
Install your bzImage
Reboot

Congratulations, you now have an IPv6 enabled kernel!

Using the information you received by mail, configure a tunnel by doing this:

Create a tunnel called sixxs:
# ip tunnel add sixxs mode sit local [Your IPv4 Endpoint] remote [PoP IPv4 Endpoint]

Bring the tunnel interface 'sixxs' up:
# ip link set sixxs up

Fix MTU and TTL
# ip link set mtu 1280 dev sixxs
# ip tunnel change sixxs ttl 64

Configure your IPv6 endpoint on the tunnel:
# ip -6 addr add [Your IPv6 Endpoint]/[Prefix Length] dev sixxs

Route your IPv6 traffic via the SixXS PoP:
# ip -6 ro add default via [Our IPv6 endpoint] dev sixxs
Note that on Linux <2.4.20 one needs to use 2000::/3, the reason for this is explained in the linux-net archives.
