# This script does all of the necessary configuration to enable direct IPv6
# connectivity via a Hurricane Electric IPv6 tunnel from http://tunnelbroker.net
# on an Ubuntu or other Linux system when radvd is unavailable on the network,
# or for setting up radvd on the system. 

# To use this script, put it in /etc/network/if-up.d and make it executable,
# then run it by itself or restart the networking services.

# Load the kernel IPv6 module. This isn't necessary on Linode.
modprobe ipv6

# The primary internet-facing network interface
MY_IF=enp3s0

# Given under "IPv6 Tunnel Endpoints" on the tunnel details page
SERVER_V4=xxx.xxx.xxx.xxx
CLIENT_V6=2001:xxx:xxxx:xxx::2/64

# An address from your Routed /64 or /48 prefix for the local interface
LOCAL_V6=2001:xxx:xxxx:xxx::1337/64

# If you have a static IP address (such as on Linode), you can comment these out.
# Otherwise, set them to your tunnelbroker.net username and password, and your tunnel ID.
