Configure Stateless Ip/Icmp Translation; Stateless Ip/Icmp Translation - NETGEAR ProSafe FVS336Gv2 Reference Manual

ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv2
The IPv6 Tunnel Status table shows the following fields:
• Tunnel Name. The tunnel name for the 6to4 tunnel is always sit0-WAN1 (SIT stands
for Simple Internet Transition); the tunnel name for an ISATAP tunnel is isatapx-LAN,
in which x is an integer.
• IPv6 Address. The IPv6 address of the local tunnel endpoint.

Stateless IP/ICMP Translation
Stateless IP/ICMP Translation (SIIT) is a transition mechanism algorithm that translates
between IPv4 and IPv6 packet headers. Using SIIT, an IPv6 device that does not have a
permanently assigned IPv4 address can communicate with an IPv4-only device.
SIIT functions with IPv4-translated addresses, which are addresses of the format
0::ffff:0:0:0/96 for IPv6-enabled devices. You can substitute an IPv4 address in the format
a.b.c.d for part of the IPv6 address so that the IPv4-translated address becomes
0::ffff:0:a.b.c.d/96.
For SIIT to function, the routing mode must be IPv4/IPv6. NETGEAR's implementation of SIIT
lets you configure a single IPv4 address. This IPv4 address is then used in the
IPv4-translated address for IPv6 devices to enable communication between IPv4-only
devices on the VPN firewall's LAN and IPv6-only devices on the WAN.
Configure Stateless IP/ICMP Translation
For SIIT to function, the routing mode must be IPv4/IPv6 (see
on page 88). The following procedure describes how to configure SIIT.

To configure SIIT:
1. On your computer, launch an Internet browser.
