5. Forwarding

For LAN

WAN communications, the gateway normally only allows you to originate an IP

connection with a PC on the WAN; it will ignore attempts of the WAN PC to originate a

connection onto your PC. This protects you from malicious attacks from outsiders. However,

sometimes you may wish for anyone outside to be able to originate a connection to a

particular PC on your LAN if the destination port (application) matches one you specify.

This page allows you to specify up to 9 such rules. For example, to specify that outsiders

should have access to an FTP server you have running at 192.168.0.5, create a rule with that

address and Source Port =21 and Destination Port =21 (FTP port) and Protocol = TCP (FTP

runs over TCP), and click Apply. This will cause inbound packets that match to be forwarded

to that PC rather than blocked. The same IP address can be entered multiple times with

different ports.
