Chapter 6 NAT Configuration
Network Address Translation allows an IP-based network to manage its public (Internet)
addresses separately from its private (intranet) addresses. With NAT, each private IP address
can be translated to a different public address, or multiple private addresses can be aliases to a
single public one. To accomplish this, NAT software snoops both incoming and outgoing
packets on the network. It modifies the source or destination address in the IP header to reflect
the mapping between internal and external addressing for that network.
NAT functionality appears on Compex CGX3224 with low-level access to packets at the
network boundary. Several variations on NAT have also been implemented to provide
additional support for application-level protocols.
6.1 Static IP Setting (IP Forwarding)
IP forwarding is used to control access to local area networks from the Internet. It
accomplishes this by determining whether or not IP packets (messages) are exchanged
between the local network and the Internet.
Procedures
To set a static IP Address,
1. Go to NAT Config from the Command window.
2. Enter a private IP Address, such as 192.168.100.20, in the field provided and click
Save button.
Please note that you must enable the NAT function in the Configuration window if
you are using a single IP address account (fixed static IP) and want to share this
connection on your LAN.
