The Domain Name Server (DNS) group is used to resolve Fully Qualified Domain Names (FQDN) to
an IP address. This field can either be filled in or left blank. If it is left blank, your ISP will assign a
DNS address. This DNS address will also be handed off to any client obtaining an IP address from
the ProxyServer’s DHCP Server.
The Primary Server field defines the IP address of the first host that the ProxyServer will attempt to
connect to upon a user request. If this server is unavailable, the ProxyServer will attempt a
connection with the Secondary Server (if defined). The Secondary Server field defines the IP
address of the DNS server for cases where the primary server is unavailable.
The Static Routes feature allows a remote client PC access to the Internet through a pre-defined
route (static route). Static routing is normally used when a part of an internetwork can only be
reached by one particular path. Static routes are manually configured routes that specify the
transmission path a data packet must follow based on the data packet’s destination address. In the
example below, a data packet sent from the remote client PC to access the remote Internet through
the MTPSR3-200 must have IP Address 200.1.1.0 and Gateway Address 192.168.2.1 (entered as
the Static Route configuration). This determines the return path the data packet will take back to the
client PC.
