Configuration

From DHCPv6

prefix and DNS settings) through DHCPv6.

Configuration

From DHCPv6

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.

Router

Preference

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.

MTU

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
divides it into smaller fragments.

Hop Limit

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.

Advertised

Prefix Table

Configure this table only if you want the ZyWALL to advertise a fixed prefix to the
network.

Add

Click this to create an IPv6 prefix address.

Edit

Select an entry in this table and click this to modify it.

Remove

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.

IPv6

Address/

Prefix Length

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.

Advertised

Prefix from

DHCPv6 Prefix

Delegation

Use this table to configure the network prefix if you want to use a delegated prefix as
the beginning part of the network prefix.

Add

Click this to create an entry in this table.

Edit

Select an entry in this table and click this to modify it.

Remove

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.

Delegated

Prefix

Select the DHCPv6 request object to use for generating the network prefix for the
network.

Suffix

Address

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.
