ZyXEL NBG-334SH User’s Guide

The DHCP table shows current DHCP client information (including IP Address, Host Name 
and MAC Address) of all network clients using the ZyXEL Device’s DHCP server.
Configure this screen to always assign an IP address to a MAC address (and host name). Click 
Network > DHCP Server > Client List.

You can also view a read-only client list by clicking the DHCP Table 
(Details...) hyperlink in the Status screen. 

The following screen displays.

Figure 61   Client List

First DNS Server
Second DNS 

Server
Third DNS Server 

Select From ISP if your ISP dynamically assigns DNS server information (and 

the ZyXEL Device's WAN IP address). The field to the right 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 field to the right. If you chose User-Defined, but leave 

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

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

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

Device's LAN IP address displays in the field to the right (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 the WAN > Internet Connection screen) 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 None after you click Apply. 
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 computer in order to access it.

Apply

Click Apply to save your changes back to the ZyXEL Device.
