Network Setup
The Network Setup menus consist of Interface, Routes, Masquerading, SNAT, and DNAT screens. The
Interface screen is used to set up two Ethernet interfaces with funtional IP parameters for your network or
networks. Routes screen is used to define additional (network specific) IP routes. The Masquerading screen is
used to hide private addresses behind public addresses. DNAT and SNAT screens are also used to hide
private addresses, but with more control of a public access perspective (directional control).
About the Interface Screen
These settings are for setting the default gateway, host name, external name servers for the system,
configuration of IP address, mask for the installed network cards, enabling/disabling Proxy ARP on each of
the interfaces, configuring aliases for each of the interfaces.
Configure the first Ethernet interface (Network Card 1) with the basic/primary network parameters. For
example, change the IP address and subnet mask of eth0 to an available, static address that matches the
network this MultiAccess is going to be used on, then click on the Save button. Confirm the pop up menu
regarding the address change and wait approximately 1 minute for the parameter change to take affect.
Then enter the new IP address in the Address bar of your browser and proceed to log back into the unit.
Configure the remaining basic parameters; Defining the default gateway, adding at least one DNS server
(this is used by the operating system to resolve names), and define a host name for the MultiAccess.
It is not necessary to configure and connect the second Ethernet interface. The intended use of the
second network interface is for more advanced applications. Use of the second interface lends flexibility to
separate applications, useful with private and public network implementations, provides an alternative
means of network access and can aid in troubleshooting. It is acceptable to have both interfaces on the
same network, as long as they have unique host addresses, or they can be on separate networks.
