How to configure Port Forwarding on the Open BAT - 1
How to configure Port Forwarding on the Open BAT
This how is an add-on to to "How to configure IP Masquerading on the Open BAT"
It describes the additional steps to configure Port Forwarding on the Open BAT through a simple
example.
General description:
A BAT configured as Access Client (Autonomous System) is associated to on a BAT configured
as Access point (External).
On the BAT client (AS) Laptop1 and SW1 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: 192.168.1.120 | 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
Devices in the Autonomous System are masqueraded by the BAT client behind the address
10.3.110.1
(Current status at the end of the howto "How to configure IP Masquerading on the Open BAT")
We will configure Port Forwarding as follow:
To open a Telnet session on SW1, Laptop3 (or any other device on the EXTERNAL side) must
access 10.3.110.1 on port 10
The BAT client will then reforward these data to 192.168.1.120 (SW1) on port 23 (Telnet)
As the Port Forwarding 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

How to configure Port Forwarding on the Open BAT - 2
Preliminary steps
- Give the Open BAT an IP address
192.168.1.1/24 for the BAT client
10.3.110.10/24 for the BAT AP
--> Refer to the howto: "How to give an Open BAT or a WLC an IP address" if necessary
- Discover the Open BAT in LANconfig
--> Refer to the howto: "How to add a BAT or a WLC in LANconfig" if necessary
--> Take care that LANconfig 9.10 at least must be used
- Configure the Open BAT as AP and client and connect them per Wireless
--> Refer to the howtos "How to configure an Open BAT as Access Point" and "How to configure
