Traffic sent from a 6to4 site to a 36# native IPv6 host will be tunneled over the IPv4 Internet to a 6to4 Relay 37# Router before being delivered to the native IPv6 host. Enabling support 38# for sending/receiving traffic to/from a 6to4 Relay Router can create a 39# security risk for a 6to4 site, since there is no default trust 40# mechanism for communicating with Relay Routers. Communication support 41# with 6to4 Relay Routers has been disabled by default. ACCEPT6TO4RELAY 42# can be set to the following values: 43# NO = Disables communication with 6to4 Relay Routers 44# YES = Enables communication with 6to4 Relay Routers and thus native 45# IPv6 hosts through a 6to4 tunnel. 46# 47# When ACCEPT6TO4RELAY=YES, RELAY6TO4ADDR will be used to determine the 48# destination IPv4 address to be used as a tunnel endpoint when communicating 49# with 6to4 Relay Routers. 192.88.99.1 is the well-known 6to4 Relay Router 50# Anycast address as defined in RFC 3068.
