Connecting Data Cables to the AR450S
Connecting the router to your network:
1. Connect to the LAN.
If you have not already done so, use straight-through Ethernet patch cables to
connect the device(s) on your private network (LAN) to the router’s switch
port(s). By default, all switch ports are members of VLAN1.
2. Connect to the DMZ port.
If you have a public server to connect, use an Ethernet patch cable to connect it
to the AR450S router’s Ethernet DMZ (ETH1) port. Separating public servers
from your LAN allows the firewall to provide greater protection for your LAN.
If you have multiple public servers, you can connect them to a hub or Layer 2
switch and connect that device to the router’s DMZ port.
3. Connect to the WAN.
Caution If you intend to use a firewall, configure it before you activate
the WAN link.
Once initial configuration is complete, connect the router to the WAN. Use an
Ethernet patch cable to connect the router’s Ethernet WAN (ETH0) port to the
Ethernet port of a WAN device (such as a modem).
