 If you have previously set up your WLAN using 

the 3e-531AP devices as access points and you decide to change 

the con fi g u ra tion to gateway mode, you will need to convert 

the MAC ad dress es on each wireless device that has been set 

up so they can be seen by the reconfi gured system. This is ac-

complished by the following procedure, done on each device 

that was confi gured to use the 3e-531AP when the system was 

set up as an access point system. Pull up a System Prompt 

(“c:\” prompt, also called an MSDos prompt) on the wireless 

device’s desktop. type: arp-d and hit return. This reconfi gures 

the MAC address in the wire less device’s PC Card so that it is 

now visible to the gate way.

Chapter 3 covered the default confi guration of the 3e-531AP Wireless 

Access Point as an access point, for use as part of a host wired net work. 

This chapter covers confi guration as a gate way.  

If ad di tion al security for the wireless network is desired (dif fer en t-

i at ing it from the wired network to which it is connected), set it up in 

gateway mode. Gateway mode takes advantage of some built-in  “rout er” 

func tions, such as the gateway’s ability to do Network Address Transla-

tion (NAT), providing private IP addresses for the wire less clients.

A 3e-531AP set up in gateway mode can initiate wireless com mu ni c-

a tions to the wired network but the wired network can’t initiate com mu -

ni ca tions to the wireless network unless a specifi c net work ad dress has 

been assigned and the user on the wired network knows that address. 

The illustration on the following page diagrams the difference.
