54 Mbps Wireless Router WGR614v8 User Manual • Allow inbound access to your server. To allow inbound access to resources on your local network (for example, a Web server or remote desktop program), you can open the needed services by configuring port forwarding as described in "Changing the MTU Size" on page 5-20. • Allow certain games and applications to function correctly. Some games and applications need to allow additional inbound traffic in order to function. Port triggering can dynamically allow additional service connections, as described in "Changing the MTU Size" on page 5-20. Another feature to solve application conflicts with the firewall is Universal Plug and Play (UPnP), described in "Using Universal Plug and Play" on page 5-12. 2-22 v1.1, May 2008 Safeguarding Your Network
