# Create a 6rd tunnel on a Linux router using AT&T U-Verse Fiber/DSL.
#
# Only creates a tunnel and sets up a default route. IPv6 connectivity for LAN
# clients requires, at minimum, sending Router Advertisements (with radvd/
# dnsmasq) to the LAN interface and enabling IPv6 forwarding in the kernel.
# IPv6 firewalling with ip6tables is also a very good idea.
