what is the diference between UPnP vs Port Triggering vs Virtual Servers

[gabak]

i got a tp-link Model No. TL-WR941N and it has all those options.
I know how to use port forwading ( virtual servers )

Port forwarding (static) is the process of opening a door in the router, by the user, so that an outside person/entity can access a PC or server behind the router.
The door is always open and requires no action by the users on the LAN.

Port triggering is based on an OUTGOING request by a user on the LAN. It allows dynamic port forwarding to temporarily occur, so that the user can access services (REAL AUDIO) or gaming etc..... It assists the users behind the PC. A method of sharing a port or port forwarding range. Everything in an automatic way.

what is the diference between UPnP vs Port Triggering & Virtual Servers????????????????

All of them are basically variations of the same thing. Opening ports so that some computer behind the NAT can make a service available to the internet. Like running a game server such as Quake 3..port 27,960, or a mail server ..port 25, or a web server...port 80.

THE MANUAL METHOD...port forwarding to a static internal IP.
Virtual Servers is just a nickname some router brands give to the service you make available when you do port forwarding. Was around before "virtualized" servers came into play...so don't confuse those.

Pin Holes is another nickname some router brands (like Netopia) do for port forwarding.

FIRST AUTOMATIC METHOD...Port Triggering...the router senses when a port is trying to listen...from a service you have behind the NAT..and it opens, upon demand. It's sort of a predecessor to UPnP. It's done by the router...regardless of the OS.

MICROSOFTS AUTOMATIC METHOD...UPnP..Universal Plug 'n Play...was a protocol Microsoft came up with to automate port forwarding...or drive port triggering from the OS. The OS makes a request to open/forward ports to a router that is UPnP aware.
