Chapter 7 LAN Setup Table 19 Network > LAN > DHCP Setup LABEL First DNS Server Second DNS Server DESCRIPTION Select Obtained From ISP if your ISP dynamically assigns DNS server information (and the P-660H-T1v3s's WAN IP address). 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, UserDefined 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 P-660H-T1v3s act as a DNS proxy only when the ISP uses IPCP DNS server extensions. The P-660H-T1v3s's LAN IP address displays in the field to the right (read-only). The P660H-T1v3s tells the DHCP clients on the LAN that the P-660H-T1v3s itself is the DNS server. When a computer on the LAN sends a DNS query to the P-660H-T1v3s, the P-660H-T1v3s 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. Apply Cancel 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. Click this to save your changes. Click this to restore your previously saved settings. 7.4 The Client List Screen This table allows you to assign IP addresses on the LAN to specific individual computers based on their MAC Addresses. Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address is assigned at the factory and consists of six pairs of hexadecimal characters, for example, 00:A0:C5:00:00:02. 94 P-660H-T1v3s User's Guide
