Configuring the Firewall
Enabling Port Forwarding to Allow Access to Services
NOTE
Cisco Small Business WRV210 Administration Guide
When users send this type of request to your network via the Internet, the Router
forwards 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.
Port Forwarding and DMZ are used for similar purposes. However, Port Range
Forwarding can forward to a maximum of 10 ranges of ports on different PCs, while
a DMZ can forward all the ports for one PC. For information about DMZ, see
Configuring a DMZ to Allow Access to All Ports of a Server, page
