Port Forwarding?
So port forwarding only works with one computer? If you have two gaming computers then you are screwed? What am I not understanding?

Port Forwarding?

For the simplest home setup, with Port Forwarding on the router, it might seem that way. It depends on the flexibility of the server software. Let's take web servers as an example. Starbucks ---------- home_router --------- machine #1 (webserver:80) \ \__________ machine #2 (webserver:8080) I can start a webserver running, and instead of using port 80 (the default), I can pick a high port number outside of the 1024 reserved port numbers at the bottom of the port space. Web server software accepts alternate port numbers. Now, when sitting at Starbucks, I type http://davej.myname.com # reaches machine #1 http://davej.myname.com:8080 # reaches machine #2 There are some other protocols, which accept a small "range" of port numbers. For example, Xservers start at 6000, and 6001 would be :1, 6002 would be :2 and so on. Starbucks ---------- home_router --------- machine #1 (Xserver:6000) \ \__________ machine #2 (Xserver:6001) DISPLAY=:0 DISPLAY=:1 Depending on the protocol, it may have been designed for situations like this, or it might not. And there are probably other ways to solve this problem with static addresses on one home setup. But usually the ISP charges a monthly fee for the privilege. The scheme doesn't appear to be infinitely extensible. Only a small number of serving devices can be satisfied with this "home user" concept. I'm not an IT guy, and cannot answer this question for every conceivable networking option. There are people who will laugh at my examples, and deservedly so. ******* And IPV6 doesn't use this scheme, at all. If you switch to IPV6, things are *entirely* different and a lot more dangerous. Part of the thrill of using IPV6, is the "security by obscurity" and the inability to scan the whole number space in a reasonable time. When your ISP gives you an IPV6 address, you're basically given a whole (huge) block of addresses, and this problem... goes away. No more Port Forwarding. Every machine is exposed and must be secured (patched up to date). Paul |

Port forwarding is only needed when you run a game server that must answer incoming calls over the router. -- @~@ Remain silent! Drink, Blink, Stretch!

If your game or application can be set up for different ports, you can forward those various ports in your router to different computers. |

Maybe IPV6 makes it unnecessary or maybe it never was necessary? The help page says "Steam Client" not "Steam Server" so I presumed it was necessary for all players. |
