How do I get past my router?

[Alphathree33]

I've got two computers networked via a linksys router and the router's WAN port connects to my entire dorm.

Obviously from within network settings I can see my two computers, but I can't see anything past my router.

I realize that routers are supposed to block traffic, but how do I get around this so that I can see computers outside of my little LAN?

*sigh*
i have a belkin router and can't open up port 6667 or port 21 to use IRC or host an FTP connection (respectively). The documentation is terrible for this Belkin 4 port DSL/cable router. I've tried playing with a bunch of things, but can't get an open port. I can, however, browse the web just fine and use kazaa lite/direct connect without problem.

That says you are trying to bypass campus security whihc is a no-no here. If this is a legitimate purpose, ask your admin to allow your ip.

You would have to do one of the following - depending on exactly what you want to do with them, and how bare assed you want to be sitting

1. one to one nat - basically say any requests for the public ip forward over to the internal private IP
2. hang the machine out on the DMZ port
3. do port forwarding - whenever the router gets a request for a specific port, it sends that request over to an internal IP you specify

What do you want to do with them from outside your little lan?

Well my purposes are two fold. One, I want be able to download other people's shared files. A lot of people are sharing MP3s and things.

Another is I'd like to be able to join dorm LAN games.

There's no bypassing campus security... it's my router... I could just plug my computer right into the wall like everyone else and I would have access to all of the shared files anyway.

Look at the status of your router and see what IP address it's pulling.

Is it a public, or a private IP?

I'm not sure what you mean by public or private in the sense that it doesn't say one or the other. If by public you mean can I see it or does it just say (Private)... I am looking right now at the IP that my router is pulling from an external source.

His point being that many campuses allow one computer per user thus making routers against the service policy.

Obviously public, else he wouldn't be posting this / using Kazaa / etc.

I don't understand what the "violation of security" bit is.

He gets one IP. He has >1 computer. He NATs his one IP to allow both online.

Oh my god. Security breach. No way can anyone have a legitimate use for more than one computer!

BTW: Private IP = 10.0.x.x, 192.168.x.x, or (I forget the third set) - Public IP = anything else.
If you're looking to enable Windows File Sharing, you'll have to forward the approriate ports to a machine (TCP ports 137 & 139 IIRC) and be aware of the security risks associated with doing so. What sometimes works is putting the IP number directly in, or obtaining by a network probe of the netblock.

Thanks for the info. It is definitely public.

I don't want to share files myself. (I know how to do the appropriate port forwarding for that. )

I want to be able to see the files that other people are sharing and download those.

Right now if I go to network neighbourhood I see only my two computers. But if I were to connect directly, without going through my router (i.e. unplugging my router and rebooting... really annoying) I would see all of the computers on my dorm's network. I want to be able to see this without unplugging the router.
