6to4 Tunnel (IPv6)
Choose this option to establish an auto-tunnel in an IPv4 network (or real IPv4
Internet connection) across two independent IPv6 networks. Enter the following
parameters:
Relay IPv4 Address—Allows a 6to4 host to communicate with the native IPv6
Internet. It must have a IPv6 default gateway set to a 6to4 address that contains
the IPv4 address of a 6to4 relay router. To avoid the need for users to set this up
manually, the anycast address of 192.88.99.1 has been allocated for sending
packets to a 6to4 relay router.
•DNS Server 1 and DNS Server 2—IP addresses of the DNS servers.
Optionally, you can enter a second DNS server. The first available DNS
server is used.
•LAN IPv6 Address—Global IPv6 prefix that was assigned by your ISP for
your LAN devices, if applicable. (Check with your ISP for more information.)
•Prefix Length—IPv6 prefix length. The IPv6 network (subnet) is identified
by the initial bits of the address called the prefix. All hosts in the network
have the identical initial bits for their IPv6 address. Enter the number of
common initial bits in the network addresses. The default prefix length is 64.
•LAN Prefix Assignment
-Without any action—Does not provide Stateless or Stateful IPv6
address for LAN-side PCs.
-Configure to RA automatically—Provides Stateless IPv6 address for
LAN-side PCs.
-Configure to DHCPv6 automatically—Provides Stateful IPv6 address
for LAN-side PCs.
-Configure to RA and DHCPv6 automatically—Provides Stateless and
Stateful IPv6 addresses for LAN-side PCs.
