View the Tunnel Status and IPv6 Addresses

The IPv6 Tunnel Status screen displays the status of all active 6to4 and ISATAP tunnels and

their IPv6 addresses.

 To view the status of the tunnels and IPv6 addresses:

Select Monitoring > Router Status > Tunnel Status. The Tunnel Status screen displays:

Figure 24.

The IPv6 Tunnel Status table shows the following fields:

• T

unnel 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.

• I

Pv6 Address. The IPv6 address of the local tunnel endpoint.

Configure Dynamic DNS

Dynamic DNS (DDNS) is an Internet service that allows devices with varying public IPv4

addresses to be located using Internet domain names. To use DDNS, you need to set up an

account with a DDNS provider such as DynDNS.org, TZO.com, Oray.net, or 3322.org. (Links

to DynDNS, TZO, Oray, and 3322 are provided for your convenience as option arrows on the

DDNS configuration screens.) The wireless VPN firewall firmware includes software that

notifies DDNS servers of changes in the WAN IP address so that the services running on this

network can be accessed by others on the Internet.

If your network has a permanently assigned IP address, you can register a domain name and

have that name linked with your IP address by public Domain Name Servers (DNS).

However, if your Internet account uses a dynamically assigned IP address, you will not know

in advance what your IP address will be, and the address can change frequently—hence, the

need for a commercial DDNS service, which allows you to register an extension to its

domain, and restores DNS requests for the resulting fully qualified domain name (FQDN) to

your frequently changing IP address.

After you have configured your account information on the wireless VPN firewall, when your

ISP-assigned IP address changes, your wireless VPN firewall automatically contacts your

DDNS service provider, logs in to your account, and registers your new IP address.
