RIP
RIP (Routing Information Protocol) allows a router to exchange routing
information with other routers.
IP Pool Starting
Address
This field specifies the first of the contiguous addresses in the IP
address pool.
Pool Size This field specifies the size, or count of the IP address pool.
Remote DHCP
Server
If Relay is selected in the DHCP field above then enter the IP address
of the actual remote DHCP server here.
DNS Server
DNS Servers
Assigned by
DHCP Server
The ZyXEL Device passes a DNS (Domain Name System) server IP
address to the DHCP clients.
First DNS Server
Second DNS
Server
Third DNS Server
Select Obtained From ISP if your ISP dynamically assigns DNS
server information (and the ZyXEL Device's WAN IP address).
Select UserDefined 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
UserDefined, but leave the IP address set to 0.0.0.0, UserDefined
changes to None after you click Apply. If you set a second choice to
UserDefined, 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 only
when the ISP uses IPCP DNS server extensions. 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 real
DNS server learned through IPCP 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. You must
have another DHCP sever on your LAN, or else the computers must
have their DNS server addresses manually configured. 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.
Cancel Click Cancel to begin configuring this screen afresh.
Advanced Setup Click this button to display the Advanced LAN Setup screen and edit
