ACCEPT6TO4RELAY # can be set to the following values: # NO = Disables communication with 6to4 Relay Routers # YES = Enables communication with 6to4 Relay Routers and thus native # IPv6 hosts through a 6to4 tunnel. # # When ACCEPT6TO4RELAY=YES, RELAY6TO4ADDR will be used to determine the # destination IPv4 address to be used as a tunnel endpoint when communicating # with 6to4 Relay Routers. 192.88.99.1 is the well-known 6to4 Relay Router # Anycast address as defined in RFC 3068.
