Set the (IPv6) default route on the public 6to4 anycast address: Ip tunnel add tun6to4 mode sit ttl 64 remote any local $6to4 6to4/IPv6-prefix of the host (see 6to4 Details: Creating the prefix for instructions). Setting up a 6to4 tunnel requires several steps on the command line. Linux supports automatic 6to4-tunnelling with the tun6to4 tunnel-interface. Set the (IPv6) default route on the tunnel: Ip tunnel add sit1 mode sit remote $router-ipv4 local $host-ipv4

Up Tunnelling IPv4/IPv6 Configured tunnels ( Firewall Usage and Firewalling Examples). See the Further Reading list for links to usage examples The IPv6 part of netfilter is called via the separate command ip6tables. The Linux netfilter firewall has stateless IPv6 filtering support since 2007 with the To prefer privacy addresses and use them over the normal addresses, use: Privacy addresses are not enabled by default. Linux prefers IPv6 if a DNS query results in IPv4 and IPv6 addresses being sent The required IPv6 kernel modules are (mostly) loaded automatically. IPv6 is (in most configurations) active by default and successfully performs stateless

Is not integrated into kernel/most base systems and has to be installed by hand Programs provide basic IPv6 functionality. Implemented into the kernel are the core functions of USAGI the 'standard' user-level The integrated USAGI version/release is unknown. The Linux kernel implements most of its IPv6 parts from
