IPLink Software Configuration Guide
10 • IP context overview
•
You can find the information regarding network address port translation (NAPT) in chapter 12,
“NAT/
NAPT configuration”
on page 128.
•
If you need to configure a physical port, chapter 13,
“Ethernet port configuration”
on page 137 or
chapter 15,
“Serial port configuration”
on page 167 may prove helpful.
•
To set up the IP router contained in IPLink software, chapter 17,
“Basic IP routing configuration”
on page
195 and chapter 18,
“RIP configuration”
on page 201 give you the required information.
•
For essential knowledge related to network security requirements, refer to chapter 19,
“Access control list
configuration”
on page 211.
•
If your network shall provide better service to selected network traffic, chapter 14,
“Link scheduler configu-
ration”
on page 148 will help you to get in-depth knowledge about quality of service (QoS) management
with IPLink software.
The following sections describe the basic tasks involved in IP context configuration. Many parameters have
acceptable default values, which in most cases do not need to be explicitly configured. Hence not all of the con-
figuration tasks below are required. Depending on your application scenario, some tasks are mandatory or
might be optional. The following tasks use a bottom-up approach, starting from the ports, followed by the
interfaces up to the services running on the IPLink. The first tasks below shall help you obtaining the necessary
overview, in view of the fact that there is always a risk getting lost in details before gaining a general under-
standing of the whole network.

Planning your IP configuration
The following subsections provide network connection considerations for several types of physical ports types.
Patton recommends that you draw a network overview diagram displaying all neighboring IP nodes and serial
connected elements. Do not begin configuring the IP context until you have completed the planning of your
IP environment.
IP interface related information
Setting up the basic IP connectivity for your IPLink requires the following information:
•
IP addresses used for Ethernet LAN and WAN ports
•
IP Subnet mask used for Ethernet LAN and WAN ports
•
Length for Ethernet cables
