ZyXEL 793H Guía Del Usuario

 Chapter 24 LAN Setup

P-793H User’s Guide

Use menu 3.2 to configure the first network, and you use menu 3.2.1 to configure the other 
two networks. Move the cursor to the Edit IP Alias field, press [SPACE BAR] to choose Yes 
and press [ENTER] to configure the second and third network.

Primary DNS 

Server
Secondary DNS 

Server

The ZyXEL Device passes a DNS (Domain Name System) server IP address (in 

the order you specify here) to the DHCP clients. 
Select From ISP if your ISP dynamically assigns DNS server information (and the 

ZyXEL Device's WAN IP address). The IP Address field below displays the (read-

only) DNS server IP address that the ISP assigns. 
Select User-Defined if you have the IP address of a DNS server. Enter the DNS 

server's IP address in the IP Address field below. If you chose User-Defined, but 

leave the IP address set to 0.0.0.0, User-Defined changes to None after you save 

your changes. If you set a second choice to User-Defined, and enter the same IP 

address, the second User-Defined changes to None after you save your changes.
Select DNS Relay to have the ZyXEL Device act as a DNS proxy. The ZyXEL 

Device's LAN IP address displays in the IP Address field below (read-only). The 

ZyXEL Device tells the DHCP clients on the LAN that the ZyXEL Device itself is the 

DNS server. When a computer on the LAN sends a DNS query to the ZyXEL 

Device, the ZyXEL Device forwards the query to the ZyXEL Device's system DNS 

server (configured in menu 1) and relays the response back to the computer. You 

can only select DNS Relay for one of the three servers; if you select DNS Relay for 

a second or third DNS server, that choice changes to 

 after you save your 

changes.
Select None if you do not want to configure DNS servers. If you do not configure a 

DNS server, you must know the IP address of a machine in order to access it.

Remote DHCP 

Server

If Relay is selected in the DHCP field above, then type the IP address of the actual 

remote DHCP server here.

TCP/IP Setup:

IP Address

Enter the LAN IP address of your ZyXEL Device in dotted decimal notation

IP Subnet Mask

Your ZyXEL Device will automatically calculate the subnet mask based on the IP 

address that you assign. Unless you are implementing subnetting, use the subnet 

mask computed by the ZyXEL Device.

RIP Direction

Press [SPACE BAR] and then [ENTER] to select the RIP direction. Options are: 

Both, In Only, Out Only or None.

Version

Press [SPACE BAR] and then [ENTER] to select the RIP version. Options are: 

RIP-1, RIP-2B or RIP-2M.

Multicast

IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to 

establish membership in a Multicast group. The ZyXEL Device supports both IGMP 

version 1 (IGMP-v1) and version 2 (IGMP-v2). Press [SPACE BAR] and then 

[ENTER] to enable IP Multicasting or select None (default) to disable it.

IP Policies

You can apply up to four policy routes for this remote node. Configure the policy 

routes in menu 25 first. See 

 for information about policy 

routes.

Edit IP Alias

The ZyXEL Device supports three logical LAN interfaces via its single physical 

Ethernet interface with the ZyXEL Device itself as the gateway for each LAN 

network. Press [SPACE BAR] to select Yes and then press [ENTER] to display 

menu 3.2.1.

When you have completed this menu, press [ENTER] at the prompt [Press ENTER to Confirm…] to 

save your configuration, or press [ESC] at any time to cancel.
