N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 User Manual Firewall Rules to Control Network Access By default your router blocks any inbound traffic from the Internet to your computers except for replies to your outbound traffic. You might need to create exceptions to this rule to allow remove computers to access a server on your local network or to allow certain applications and games to work correctly. Your router provides port forwarding and port triggering got creating these exceptions.
N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 User Manual • The source address is replaced with your router’s public IP address. This is necessary because your computer uses a private IP address that is not globally unique and cannot be used on the Internet. • The source port number is changed to a number chosen by the router, such as 33333. This is necessary because two computers could independently be using the same session number.
N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 User Manual also sends an “identify” message to your computer on port 113. Using port triggering, you can tell the router, “When you initiate a session with destination port 6667, you have to also allow incoming traffic on port 113 to reach the originating computer.” Using steps similar to the preceding example, the following sequence shows the effects of the port triggering rule you have defined: 1.
N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 User Manual A typical application of port forwarding can be shown by reversing the client-server relationship from our previous Web server example. In this case, a remote computer’s browser needs to access a Web server running on a computer in your local network.
N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 User Manual • Port forwarding requires that you specify the computer’s IP address during configuration, and the IP address can never change. • Port triggering requires specific outbound traffic to open the inbound ports, and the triggered ports are closed after a period of no activity. • Port forwarding is always active and does not need to be triggered.
N600 Wireless Dual Band Gigabit ADSL2+ Modem Router DGND3700 User Manual You can usually determine this information by contacting the publisher of the application or user groups or newsgroups.
