Networking Configuring IPv6 Addressing 2 ISATAP Tunnels Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) is used to transmit IPv6 packets between dual-stack nodes over an IPv4 network. The security appliance is one endpoint (a node) for the tunnel. You must set a local endpoint as well as the ISATAP Subnet Prefix that defines the logical ISATAP subnet to configure a tunnel. STEP 1 Click Networking > IPv6 > ISATAP Tunnels. The ISATAP Tunnels window opens. Any existing tunnels are listed in the List of Available ISATAP Tunnels table. STEP 2 To add an ISATAP tunnel, click Add. Other options: Click the Edit button to edit an entry. To delete an entry, check the box and then click Delete. To select all entries in the table, check the box at the left side of the heading row. After you click Add or Edit, the ISATAP Tunnel Configuration window opens. STEP 3 Enter the following information: • ISATAP Subnet Prefix: Enter the 64-bit subnet prefix that is assigned to the logical ISATAP subnet for this intranet. You can get the prefix from your ISP or Internet registry, or derive it from RFC 4193. • Local End Point Address: Enter the endpoint address for the tunnel that starts with this router. The endpoint can be the LAN interface (assuming the LAN is an IPv4 network), or a specific LAN IPv4 address. • IPv4 Address: Enter the local end point address if not the LAN IPv4 address. STEP 4 Click Apply to save your settings. Cisco SA500 Series Security Appliances Administration Guide 86
