ZyWALL 110/310/1100 Series User’s Guide
165
IP Address This field is enabled if you select Use Fixed IP Address.
Enter the IP address for this interface.
Subnet Mask This field is enabled if you select Use Fixed IP Address.
Enter the subnet mask of this interface in dot decimal notation. The subnet mask
indicates what part of the IP address is the same for all computers in the network.
Gateway This field is enabled if you select Use Fixed IP Address.
Enter the IP address of the gateway. The ZyWALL sends packets to the gateway when it
does not know how to route the packet to its destination. The gateway should be on the
same network as the interface.
Metric Enter the priority of the gateway (if any) on this interface. The ZyWALL decides which
gateway to use based on this priority. The lower the number, the higher the priority. If
two or more gateways have the same priority, the ZyWALL uses the one that was
configured first.
IPv6 Address
Assignment
These IP address fields configure an IPv6 IP address on the interface itself.
Enable Stateless
Address Auto-
configuration
(SLAAC)
Select this to enable IPv6 stateless auto-configuration on this interface. The interface
will generate an IPv6 IP address itself from a prefix obtained from an IPv6 router in the
network.
Link-Local
address
This displays the IPv6 link-local address and the network prefix that the ZyWALL
generates itself for the interface.
IPv6 Address/
Prefix Length
Enter the IPv6 address and the prefix length for this interface if you want to use a static
IP address. This field is optional.
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.
Gateway Enter the IPv6 address of the default outgoing gateway using colon (:) hexadecimal
notation.
Metric Enter the priority of the gateway (if any) on this interface. The ZyWALL decides which
gateway to use based on this priority. The lower the number, the higher the priority. If
two or more gateways have the same priority, the ZyWALL uses the one that was
configured first.
Address from
DHCPv6 Prefix
Delegation
Use this table to have the ZyWALL obtain an IPv6 prefix from the ISP or a connected
uplink router for an internal network, such as the LAN or DMZ. You have to also enter a
suffix address which is appended to the delegated prefix to form an address for this
interface. See Prefix Delegation on page 107 for more information.
To use prefix delegation, you must:
• Create at least one DHCPv6 request object before configuring this table.
• The external interface must be a DHCPv6 client. You must configure the DHCPv6
request options using a DHCPv6 request object with the type of prefix-delegation.
• Assign the prefix delegation to an internal interface and enable router
advertisement on that interface.
