Configure ISATAP Automatic Tunneling

If your network is an IPv4 network or IPv6 network that consists of both IPv4 and IPv6 
devices, you need to make sure that the IPv6 packets can travel over the IPv4 intranet by 
enabling and configuring Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) 
tunneling.

ISATAP is a LAN tunnel mechanism in which the IPv4 network functions as a virtual IPv6 
local link. Each IPv4 address is mapped to a link-local IPv6 address, that is, the IPv4 address 
is used in the interface portion of the IPv6 address. ISATAP tunneling is used intra-site, that 
is, between addresses in the LAN. For more information about link-local addresses, see 

If you do not use a stateful DHCPv6 server in your LAN, you need to 

configure the Router Advertisement Daemon (RADVD), and set up 
ISATAP advertisement prefixes (which are referred to as 
Global/Local/ISATAP prefixes) for ISATAP tunneling to function 
correctly. For more information, see 

page 73.

The wireless VPN firewall determines the link-local address by concatenating the IPv6 
address with the 32 bits of the IPv4 host address:

For a unique global address:

 

fe80:0000:0000:0000:0000:5efe (or fe80::5efe) is concatenated with the IPv4 address. 
For example, fe80::5efe with 10.29.33.4 becomes fe80::5efe:10.29.33.4, or in 
hexadecimal format, fe80::5efe:a1d:2104.

For a private address:

 

fe80:0000:0000:0000:0200:5efe (or fe80::200:5efe) is concatenated with the IPv4 
address. For example, fe80::200:5efe with 192.168.1.1 becomes 
fe80::200:5efe:192.168.1.1, or in hexadecimal format, fe80::200:5efe:c0a8:101.
