DESCRIPTION
Select this to have the ZyWALL indicate to hosts to obtain DNS information through
DHCPv6.
Clear this to have the ZyWALL indicate to hosts that DNS information is not available in
this network.
Select the router preference (Low, Medium or High) for the interface. The interface
sends this preference in the router advertisements to tell hosts what preference they
should use for the ZyWALL. This helps hosts to choose their default router especially
when there are multiple IPv6 router in the network.
Note: Make sure the hosts also support router preference to make this function work.
The Maximum Transmission Unit. Type the maximum size of each IPv6 data packet, in
bytes, that can move through this interface. If a larger packet arrives, the ZyWALL
discards the packet and sends an error message to the sender to inform this.
Enter the maximum number of network segments that a packet can cross before
reaching the destination. When forwarding an IPv6 packet, IPv6 routers are required to
decrease the Hop Limit by 1 and to discard the IPv6 packet when the Hop Limit is 0.
Configure this table only if you want the ZyWALL to advertise a fixed prefix to the
network.
Click this to create an IPv6 prefix address.
Select an entry in this table and click this to modify it.
Select an entry in this table and click this to delete it.
This field is a sequential value, and it is not associated with any entry.
Enter the IPv6 network prefix address and the prefix length.
The prefix length indicates what the left-most part of the IP address is the same for all
computers in the network, that is, the network address.
This table is available when the Interface Type is internal. Use this table to
configure the network prefix if you want to use a delegated prefix as the beginning part
of the network prefix.
Click this to create an entry in this table.
Select an entry in this table and click this to modify it.
Select an entry in this table and click this to delete it.
This field is a sequential value, and it is not associated with any entry.
Select the DHCPv6 request object to use for generating the network prefix for the
network.
Enter the ending part of the IPv6 network address plus a slash (/) and the prefix
length. The ZyWALL will append it to the selected delegated prefix. The combined
address is the network prefix for the network.
For example, you got a delegated prefix of 2003:1234:5678/48. You want to divide it
into 2003:1234:5678:1111/64 for this interface and 2003:1234:5678:2222/64 for
another interface. You can use ::1111/64 and ::2222/64 for the suffix address
respectively. But if you do not want to divide the delegated prefix into subnetworks,
enter ::0/48 here, which keeps the same prefix length (/48) as the delegated prefix.
This is the final network prefix combined by the delegated prefix and the suffix.
Note: This field displays the combined address after you click OK and reopen this
screen.
