IP Setup
The IP Port Setup dialog box allows you change the IP routing capabilities, add or delete logical
WANs, enable the DHCP server, assign DNS address, and define default routes. The initial routing
capabilities were established during the software installation. You can change IP routing parameters
by clicking on the Advanced tab and changing, for example, the RIP Response Time or RIP Route
Aging Time. The WAN tab allows you to change the WAN port IP address, the remote address, and
if logical WAN ports are being added for frame relay, you can add them by clicking on the Add button.
The Ethernet IP Setup dialog box displays the parameters for your Ethernet port with the IP Address
and IP Mask established during the initial loading of the software.
An IP address is a combination of a network number and a host number or ID. IP address masks are
used to specify the network or subnet portion of the IP address. IP addresses and masks are 32-bit
values. These are usually provided in what is known as the dotted decimal notation. In this notation,
each 8-bit portion of the address is given a decimal quantity separated by a dot. For example,
192.2.10.1. The RASFinder expects all IP addresses to be provided in dotted decimal notation.
Among IP addresses, address 0.0.0.0 and 127.?.?.? cannot be specified as they are special case
addresses not used on the internetwork for addressing. For Class A, B, and C addresses, you will
usually specify address masks of 255.0.0.0, 255.255.0.0 and 255.255.255.0 respectively unless other
subnets have been set up.
The net mask specifies the network or subnet portion of an IP address. The net mask is a 32-bit
value presented in a dotted decimal notation.
On the IP Port Setup window, you can easily switch from the Ethernet port dialog box to any of the
three WAN port windows by clicking on the corresponding “tab.” Also, clicking on the Advanced
button will open the IP General Setup window.
The (Ethernet and WAN) IP Port Setup windows provide the capability to disable or enable IP routing
on the selected port, change the port IP Address, IP mask, and remote IP address. The Port Setup
windows determine how all the RASFinder ports are configured.
