ZyXEL Communications manual Note You must know the IP address assigned to the G-1000, again

G-1000 User’s Guide

If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network.

Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.2, for your G-1000, but make sure that no other device on your network is using that IP address.

The subnet mask specifies the network number portion of an IP address. Your G-1000 will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the G-1000 unless you are instructed to do otherwise.

The following table describes the labels in this screen.

Table 8 Wizard 3: IP Address Assignment

LABEL	DESCRIPTION
IP Address Assignment
Get automatically from	Select this option if your G-1000 is using a dynamically assigned IP address
DHCP	from a DHCP server each time.
	Note: You must know the IP address assigned to the G-1000
	(by the DHCP server) to access the G-1000 again.
Use fixed IP address	Select this option if your G-1000 is using a static IP address. When you select
	this option, fill in the fields below.
IP Address	Enter the IP address of your G-1000 in dotted decimal notation.
	Note: If you changed the G-1000's IP address, you must use
	the new IP address if you want to access the web configurator
	again.
IP Subnet Mask	Type the subnet mask.
Gateway IP Address	Type the IP address of the gateway. The gateway is an immediate neighbor
	of your G-1000 that will forward the packet to the destination. The gateway
	must be a router on the same segment as your G-1000's LAN or WLAN port.
