LABEL DESCRIPTION
IP Address Enter the IP address for this interface.
Subnet Mask 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 option appears when Interface Type is external or general. Enter the IP
address of the gateway. The ZyWALL/USG 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 This option appears when Interface Type is external or general. Enter the priority
of the gateway (if any) on this interface. The ZyWALL/USG 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/USG uses the one that was configured
first.
Enable IGMP Select this to allow the ZyWALL/USG to act as an IGMP proxy for hosts connected on
Support the IGMP downstream interface.
IGMP Version: Select the IGMP version to be used on this ZyWALL/USG interface.
IGMP Upstream Enable IGMP Upstream on the interface which connects to a router running IGMP that
is closer to the multicast server.
IGMP Enable IGMP Downstream on the interface which connects to the multicast hosts.
Downstream
IPv6 Address These IP address fields configure an IPv6 IP address on the interface itself.
Assignment
Enable Stateless Select this to enable IPv6 stateless auto-configuration on this interface. The interface
Address Auto-
will generate an IPv6 IP address itself from a prefix obtained from an IPv6 router in the
configuration
network.
(SLAAC)
Link-Local This displays the IPv6 link-local address and the network prefix that the ZyWALL/USG
address
generates itself for the interface.
IPv6 Address/ Enter the IPv6 address and the prefix length for this interface if you want to use a
Prefix Length
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/USG 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/USG uses the
one that was configured first.
Address from Use this table to have the ZyWALL/USG obtain an IPv6 prefix from the ISP or a

Chapter 9 Interfaces
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.
