3.2. IPv6 Support

3.2. IPv6 Support
All the IP addresses discussed so far are of the IPv4 type. The IP address standard IPv6 is designed
as a successor to IPv4 with the principal advantage of providing a much larger 128 bit address
space. Among many other advantages, the large number of available global IPv6 addresses means
that NAT is no longer required to share a limited number of public IPv4 addresses.
NetDefendOS Configuration Objects Supporting IPv6
The following parts of NetDefendOS provide IPv6 support:
• The address book.
• Routing tables.
• Routing rules.
• IP rules (excluding some actions).
Adding an IPv6 Address
IPv6 address objects are created in the NetDefendOS address book as objects which are distinct
from IPv4 objects.
Only the all-nets6 object (IPv6 address ::/0) already exists in the address book. This means that the
IPv6 address and network objects associated with an interface must first be created.
Example 3.6. Adding IPv6 Host Addresses
Assume that an IPv6 address and network have to be associated with the wan interface. This example adds two
new IPv6 address objects to the address book consisting of the network wan_net6 (the IPv6 prefix 2001:DB8::/32)
and the single IP address wan_ip6 (2001:DB8::1) within that network.
Command-Line Interface
gw-world:/> add Address IP6Address wan_net6 Address=2001:DB8::/32
gw-world:/> add Address IP6Address wan_ip6 Address=2001:DB8::1
Web Interface
Add the network address (the IPv6 prefix):
1. Go to: Objects > Address Book > Add > IP6 Address
2. Specify a suitable name for the object, in this case: wan_net6
3. Enter 2001:DB8::/32 for the IP6 Address
4. Click OK
Add the IP address:
1. Go to: Objects > Address Book > Add > IP6 Address
2. Specify a suitable name for the object, in this case: wan_ip6
3. Enter 2001:DB8::1 for the IP6 Address
