Dual-Band Wireless A/G Broadband Router
57
The
Port Forwarding
screen (Figure 6-26) sets up public services on your net-
work, such as web servers, ftp servers, e-mail servers, or other specialized
Internet applications. (Specialized Internet applications are any applications
that use Internet access to perform functions such as videoconferencing or
online gaming. Some Internet applications may not require any forwarding.)
When users send this type of request to your network via the Internet, the
Router will forward those requests to the appropriate PC. Any PC whose port
is being forwarded must have its DHCP client function disabled and must have
a new static IP address assigned to it because its IP address may change when
using the DHCP function.
