This lesson describes step by step how to configure IP masquerading on OpenBAT frequently
used to connect autonomous systems (AS).
We'll use for that a simple example:
A BAT configured as Access Client (Autonomous System) connected on a BAT configured as
Access point (External).
On the BAT client (AS) Laptop1 and Laptop2 are connected to ETH-1
Laptop 1: IP address: 192.168.1.29 | Mask: 255.255.255.0 | GW: 192.168.1.1
Laptop 2: IP address: 192.168.1.28 | Mask: 255.255.255.0 | GW: 192.168.1.1
On THE BAT AP Laptop3 is connected to ETH-1
IP address: 10.3.110.19 | Mask: 255.255.255.0 | No gateway
When devices in the AS communicate with devices on the external side, their address is
translated and take the BAT Client external interface address.
In our example, 192.168.1.29 and 192.168.1.28 are tranlated into 10.3.110.1
As the IP masquerading configuration is done on the client only, this lesson describes only the
client configuration
LANconfig is used as configuration tool.
Rel 9.10 at least is required on the OpenBAT client
