Port Forwarding

• However, there are situations when specific ports must be opened so that certain programs and applications can communicate with devices on different networks
• Port forwarding is a rule-based method of directing traffic between devices on separate networks
• Port triggering allows the router to temporarily forward data through inbound ports to a specific device
• You can use port triggering to forward data to a computer only when a designated port range is used to make an outbound request

Wireless routers typically block TCP and UDP ports to prevent unauthorized access in and out of a LAN
