Traffic sent from a 6to4 site to a 37# native IPv6 host will be tunneled over the IPv4 Internet to a 6to4 Relay 38# Router before being delivered to the native IPv6 host. Enabling support 39# for sending/receiving traffic to/from a 6to4 Relay Router can create a 40# security risk for a 6to4 site, since there is no default trust 41# mechanism for communicating with Relay Routers. Communication support 42# with 6to4 Relay Routers has been disabled by default. ACCEPT6TO4RELAY 43# can be set to the following values: 44# NO = Disables communication with 6to4 Relay Routers 45# YES = Enables communication with 6to4 Relay Routers and thus native 46# IPv6 hosts through a 6to4 tunnel. 47# 48# When ACCEPT6TO4RELAY=YES, RELAY6TO4ADDR will be used to determine the 49# destination IPv4 address to be used as a tunnel endpoint when communicating 50# with 6to4 Relay Routers. 192.88.99.1 is the well-known 6to4 Relay Router 51# Anycast address as defined in RFC 3068. This value may be changed to 52# the IPv4 unicast address of a particular 6to4 Relay Router, if desired. 53# 54ACCEPT6TO4RELAY=NO 55RELAY6TO4ADDR="192.88.99.1" 56
