ZyAIR G-4100
ESSID is a unique name to identify the ZyAIR
in the wireless LAN. Enter a descriptive name.
Select a channel (range of radio frequencies
used by IEEE 802.11g wireless devices) from
the drop-down list box.
Select Disable under Security to allow
wireless devices to communicate with the
ZyAIR without any data encryption.
Select WPA to have the ZyAIR perform user
authentication and data encryption. WPA's
data encryption is stronger than WEP. Type a
pre-shared key from 8 to 63 case-sensitive
ASCII characters (including spaces and
symbols). Use the advanced wireless setup
screen if you want to use WPA with a RADIUS
server (see the User's Guide for details).
Select the WEP (Wired Equivalent Privacy)
check box to have the ZyAIR encrypt data
frames before transmitting them over the
wireless network. Select 64 Bit or 128 Bit
WEP encryption and enter a key of the length
described in the field.
Select No to not have the ZyAIR redirect e-
mail in the event that a subscriber's e-mail
server is unreachable from the ZyAIR.
Select Yes to have the ZyAIR redirect
subscribers' e-mail to the designated SMTP
server (must be reachable from the ZyAIR) in
the event that the subscriber's own e-mail
server is unreachable from the ZyAIR. E-mail
recipients see messages as if they came from
the subscriber's regular e-mail server not the
"backup" e-mail server.
When you select Yes, enter the e-mail
(SMTP) server's domain name (up to 50
characters) or IP address.
Enter the port number (25, or between 2500
and 2599) for the mail server.
