# Script for configuring OpenWrt to create a new 'henet' interface that
|
|
# uses '6in4' encapsulation to send your IPv6 packets inside IPv4 packets.
|
|
# It uses Hurricane Electric as the tunnel at http://www.tunnelbroker.net/
|
|
#
|
|
# There are a few steps to set this up:
|
|
# 1) Go to the Tunnelbroker.net site to set up your free account
|
|
# 2) From its main page, click "Create Regular Tunnel"
|
|
# - Enter your IP address in "IPv4 Endpoint" (paste in the address you're "viewing from")
|
|
# - Select a nearby Tunnel Server
|
|
# - Click "Create Tunnel"
|
|
# 3) On the resulting Tunnel Details page, click "Assign /48" to get a /48 prefix
|
|
# 4) From the Tunnel Details page, copy and paste the matching values to the variables below
|
|
# Note: The User_Name is the name you used to create the account
|
|
# Note: Find the Update_Key on the Advanced Tab of the Tunnel Details page.

User_Name=abdcef
|
|
Tunnel_ID=123456
|
|
Server_IPv4_Address=123.45.67.89
|
|
Client_IPv6_Address=2001:470:abcd:ef::/64
|
|
Routed_48=2001:470:abcd::/48
|
|
Update_Key=AbCDeF54321vWxYz
|
|
|
|
# 5) Finally, ssh into the router and execute this script with these steps:
|
|
#
|
|
# ssh root@192.168.1.1 # use your router's address
|
|
# cd /tmp
|
|
# cat > tunnel.sh
|
|
# [paste in the contents of this file, then hit ^D]
|
|
# [edit the script to match your tunnelbroker values (see #4 above)]
|
|
# sh tunnel.sh
|
|
# [Restart your router. This seems to make a difference.]
|
|
#
|
|
# Presto! Your tunnel is set up. You should now be able
|
|
# communicate directly with IPv6 devices.
|
|
|
|
# ==============================================
|
|
# Download and update all the interesting packages
|
|
# Some of these are pre-installed, but there is no
|
|
# harm in updating/installing them a second time.
|
|
opkg update
|
|
opkg install 6in4
|
|
|
|
# ==============================================
|
|
# Create a 6in4 interface named 'henet' to tunnel IPv6.

|
# Re-establishing the Tunnel
|
|
#
|
|
# The automatic re-establishment code of the 6in4 module appears not always to work.
|
|
# If the 6in4 tunnel goes down, you may need to re-establish it manually,
|
|
# say, when your external IP address changes.
|
|
#
|
|
# To re-establish the tunnel, simply paste the following URL (with the parameters defined above).
|
|
# into your browser. You should get a cryptic "OK" response.
|
|
#
|
|
# User_Name is your user account name
|
|
# Update_Key is the Update Key shown above
|
|
# Tunnel_ID is the Tunnel ID
|
|
# https://User_Name:Update_Key@ipv4.tunnelbroker.net/nic/update?hostname=Tunnel_ID
|
|
#
|
|
# --- end of script ---
|
|
#
|
|
# Final Steps:
|
|
# 1) Hit Ctl-D
|
|
# 2) Edit six lines of the file (User_Name through Update_Key) to add your tunnelbroker values
|
|
# 3) Type: sh tunnel.sh
