DHCP Setup |
| |
|
| |
DHCP | If set to Server, your ZyXEL Device can assign IP addresses, an IP | |
| default gateway and DNS servers to Windows 95, Windows NT and | |
| other systems that support the DHCP client. | |
| If set to None, the DHCP server will be disabled. | |
| If set to Relay, the ZyXEL Device acts as a surrogate DHCP server | |
| and relays DHCP requests and responses between the remote server | |
| and the clients. Enter the IP address of the actual, remote DHCP | |
| server in the Remote DHCP Server field in this case. | |
| When DHCP is used, the following items need to be set: | |
|
| |
IP Pool Starting | This field specifies the first of the contiguous addresses in the IP | |
Address | address pool. | |
|
| |
Pool Size | This field specifies the size, or count of the IP address pool. | |
|
| |
Remote DHCP | If Relay is selected in the DHCP field above then enter the IP | |
Server | address of the actual remote DHCP server here. | |
|
| |
DNS Server |
| |
|
| |
DNS Servers | The ZyXEL Device passes a DNS (Domain Name System) server IP | |
Assigned by DHCP | address to the DHCP clients. | |
Server |
| |
|
| |
First DNS Server | Select Obtained From ISP if your ISP dynamically assigns DNS | |
Second DNS | server information (and the ZyXEL Device's WAN IP address). | |
| ||
Server | Select | |
Third DNS Server | Enter the DNS server's IP address in the field to the right. If you | |
chose | ||
| ||
| Defined changes to None after you click Apply. If you set a second | |
| choice to | |
| ||
| 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 | |
| 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. | |
