What is a Router?


Recommended Posts

Well, try and see what happens. You should be okay. A router is a device that can emulate a DHCP server and it grants internal IP addresses. Those addresses won't work if you try to host a game outside of your home LAN. Those IP's are distinguished by addresses that are usually 192.168.x.x

A router is a box, in fact, it is network component, a kind of specialised simple computer, that knows where to "route" internet traffic that comes through it, so that it gets to its final destination. Routers make the internet what it is.

If you don't see (and can't kick) a box (probably made by Cisco smile.gif) in your setup, then you don't have one.

Matt, correct me if I am wrong, but I think you are referring to a proxy, not a router.

I think this issue is the Proxy.

I can play through a router at work.

Virtually ALL that travels across the internet goes through routers, (again Mostly Cisco smile.gif )

Its the Proxy routers which are like software emulators (sort off) that does not give you a true IP that cause problems here.

Yeah, I was trying to just explain a simple situation that one of the testers encountered earlier. What I really should have called it is a switch or what they now call an home internet router, which has the same feature set of a hub but with more active components, like internal IP addressing and security. If you have a device like that which is then plugged into your broadband device (DSL or Cable modem) than it may grant special IP addresses to all computers connected to it. Usually those IP's will be the special range that is reserved for home LAN use, namely the infamous 192.168.x.x ones. If you are getting 192.168.x.x as your IP then you aren't going to be able to host the game as no one will be able to find you on the internet. Now then, you MIGHT be able to host if you can find what your TRUE IP address really is, this would be the address that the broadband device hands out, in this case to the router/switch. I don't have such a switch to test and I tend to doubt that it would work but it could and if someone has such a rig then please contact me and we can do some more testing.

See, I was really just trying to keep this all simple. wink.gif

Note: The above hardware is NOT the same as a HUB. A hub (although there new ones of those to) basically doesn't give you any more IP's then what your ISP gives you. A switch or router CAN give you more connections beyond what your ISP has provided you. This can also be done via dedicated proxy'firewall software like Wingate and that's a whole other topic I don't want to get into right now! wink.gif

So you can't serve if you have a router.

Don't know if I have one. I have two computers networked, both are connected to a cable modem. Both computers have their own IP number. Is that a Router or will I be able to serve a game?<HR></BLOCKQUOTE>

No, this is not a router. If all you have is just the cable modem provided by your ISP, then you have no router involved in your setup. If in fact each of your 2 pc's have their own "unique" IP address assigned by the ISP, then you will have no problems whatsoever playing CM against another opponent on the Internet as either host or client. You're toughest problem will probably be deciding which computer to use.

Keep in mind I'm assuming when you said each pc has an IP address and attached to the cable modem, that the IP address is in fact assigned by your ISP for use on the internet and NOT a locally assigned IP address for the internal network such as 192.168.0.1.

In a situation such as mine, I have a 'single' IP address assigned by my ISP but have a 3 computer network. Thus to get all 3 on the internet, you have to 'share' this address/connection. There are various ways to do this. The way I've done it is to buy a Linksys Cable/DSL router. This not only has a built in 4 port 10/100mbs ethernet switch, but also shares the single IP address/connection for all 3 computers to use. However, there can be issues with getting pc's in this type of setup to run multiplayer games across the internet because of the sharing involved. (Different routers/devices or even software solutions for sharing may or may not have the same issues.) With you, you apparently have a unique internet IP address for each pc and no sharing is needed, thus it's just like having 2 completely seperate pc's on the internet.

If you are using a linksys cable/dsl 4 port router (like myself), it may be possible to host games. You need to go to your routers control panel, which is located within a web browser. Type in 192.168.1.1 in your web browser to get to the control panel. Then select the "advanced" tab. Then you will see a tab called "DMZ Host", Select that tab. Then you will see an IP number: 192.168.1 with a blank space after it. Just fill in the blank space with the IP number that you want to "open up" for tcp/ip internet games.Then hit apply. Make sure the screen refreshes itself. then you know you have selected it. This will let you host a game. It basically diasables the firewall, so you can be "seen" by the other computer that is joining you.

Panther,

To add to what you wrote, the person joining the game has to enter the IP address you were assigned by your ISP, not the 192.168.x.x number. For example, if your ISP assigned you 10.10.10.10 and the router assigns your machine 192.168.1.100, you would enter 100 in the DMZ box. The person connecting to you would enter 10.10.10.10 in CM.
