Changing IP Parameters
The IP Setup dialog box establishes the IP addressing for your LAN and WAN ports. To change the
IP Setup parameters that were configured during the Wizard Setup, click on the IP button in the
Proxy Setup menu. The IP Setup dialog is displayed.
The Port Selection list displays the ports that are available for IP configuration. Ports include: LAN,
WAN 1, WAN 2 and WAN 3. Once you have chosen a port from this list, its parameters will be
displayed in the group to the right. For the LAN port you must statically assign a valid IP Address
and subnetwork mask (Net Mask) to suit your network setup. Therefore, when the LAN port is
highlighted in the Port Selection list, the ISP Assigns Dynamic Address field is disabled. Normally,
on a WAN port, the ISP assigns a dynamic address when the port comes up. If this is not the case,
you need to uncheck this control and statically assign a valid Internet address and net mask.
The LAN network of the ProxyServer connects to a host of clients that will go through the proxy
server in order to access servers on the internetwork. The Client Side Internet Parameters group
defines the parameters that affect the ProxyServer’s ability to serve these clients.
The ProxyServer supports Domain Name Server (DNS) for the terminal server application. This is a
built-in Telnet client that can connect a call coming in on a WAN port from a Telnet host. When a user
dials into the system to get connected to a Telnet server, the ProxyServer will prompt for a Telnet host
address. The user can type in a dotted decimal IP address, or the domain name of the host.
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.
Note: When the Primary and Secondary Server fields are left undefined (default), applications like
terminal server will not support domain names.
