The Remote Access Dial-in User Service
(RADIUS) is one of the most common protocols
used to carry authorization, authentication, and
configuration information between a RADIUS
server on the WAN and PCs on your LAN.
Choosing RADIUS will allow the DFL-600 to
connect PCs on your LAN to a RADIUS server
on the WAN.
802.1x is a standard for passing the Extensible
Authentication Protocol (EAP) packets over a
LAN. You should enable this if there are any
802.1x devices between the DFL-600 and the
RADIUS server on the WAN. Clicking on the
Edit link (which appears when you enable
802.1x) will open the 802.1x Device
Configuration page, as shown below.
If you have PCs on your LAN that do not require
RADIUS user authentication to access the
Internet (or other networks through your ISP),
you can use Enable 802.1x, and then click the
Edit link. This will allow you to enter the IP
Address and IP (subnet) Mask of PCs on your
LAN that need to bypass the RADIUS user
authentication. PCs (and network devices)
whose IP Addresses and IP (subnet) Masks are
entered on the 802.1x Device Configuration
page will be allowed to access the Internet
without RADIUS user authentication.
Enter the IP address of the RADIUS server on
the WAN that you will use to authenticate users
on your LAN. Your ISP should provide you
with this address.
Enter the TCP/UDP port number that the
RADIUS server will use to connect to PCs on
your LAN. The default port number for
authentication is 1812.
Enter the TCP/UDP port number that the
