What is port mapping configuration?
In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.
Is port mapping safe?
Port Forwarding is not that risky because it relies on your network safety and the targeted ports that you are using. The whole process is actually safe as long as you have a security firewall or a VPN connection on your computer or network.

Should port forwarding be enabled?
Port forwarding is an excellent way to preserve public IP addresses. It can protect servers and clients from unwanted access, “hide” the services and servers available on a network and limit access to and from a network. Port forwarding is transparent to the end-user and adds an extra layer of security to networks.
What is the difference between port forwarding and port triggering?
Port forwarding opens the specified data ports all the time and devices must use static IP addresses. Port trigger only opens the incoming port when a LAN device requests access to the trigger port. Unlike port forwarding, port trigger does not require static IP addresses for LAN devices.
