Caution:
If you have previously set up your WLAN using
the 3e–525C–3 devices as access points and you decide to change
the configuration to gateway mode, you will need to convert
the MAC addresses on each wireless device that has been set up
so they can be seen by the reconfigured system. This is accom-
plished by the following procedure, done on each device that
was configured to use the 3e–525C–3 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 reconfigures the MAC
address in the wireless device’s PC card so that it is now visible
to the gateway.
Chapter 4: Gateway Configuration
Introduction
Chapter 3 covered the default configuration of the 3e–525C–3 Wireless
Access Point as an access point, for use as part of a host wired network.
This chapter covers configuration as a gateway.
If additional security for the wireless network is desired (differenti-
ating it from the wired network to which it is connected), set it up in
gateway mode. Gateway mode takes advantage of some built-in “router”
functions, such as the gateway’s ability to do Network Address Transla-
tion (NAT), providing private IP addresses for the wireless clients.
The illustration on the following page shows the difference between
AP mode and Gateway mode.
