DHCP, DNS and Time

Note: In Relay mode, the DHCP server may unicast the DHCP ACK message to the

￿DHCP Client. So proper routes should be configured at the server to enable it to reach the DHCP Client subnet.

3.2DNS Proxy

DNS (Domain Name System) is the protocol used to translate Domain Names to IP Addresses. DNS is an essential component of internet use, since it allows you to attach easy-to-remember domain names (such as www.dlink.com) to hard-to-remember IP Addresses. The DNS Servers maintain the database of Domain Name to IP Address mappings. All user systems (PCs) contain a DNS Client which communicates with the DNS Server to resolve any Domain Name.

With multiple WAN links, each ISP may provide a different set of DNS Servers to be used. And it is a cumbersome task to configure all the user PCs with the correct DNS Server IP Addresses. This problem can be overcome with the use of router’s DNS Proxy feature. Here, the router’s LAN IP Address can be configured as the DNS server at all the end user systems. The router acts as a DNS Proxy, and communicates with the DNS Servers to resolve the domain names on behalf of the user systems.

Select Misc → DNS Proxy to configure DNS Proxy Settings as explained below.
