LANs and WANs
Your DIR-430 is a network device that connects two networks; Local Area
Network (LAN) (the group of PCs in your home or office) and the Wide Area
Network (WAN), that is, the Internet. The Gateway processes and regulates the
data that travels between these two networks.
ȱ
Your DIR-430 is "equipped" with firewall software that protects your local area
network of PCs so that users on the Internet cannot hack into your PCs, hence
keeps your local PCs secure. The DIR-430 protects your network by inspecting
the first packet coming in through the WAN connection before delivery to the final
destination on Local PCs. The DIR-430 inspects Internet port services like the web
server, ftp server, or other Internet applications, and, if allowed, it will forward
the packet to the appropriate PC on the LAN side.
DIR-430 ports connect to two sides: your 10/100 LAN ports and the Internet WAN
port. The WAN and LAN ports can transmit data at 10 Mbps or 100 Mbps.
