Port forwarding with an ethernet hub, NEED HELP

post #1 of 10
Thread Starter 
Well, I have two computers now, so I decided to get a router.

It is a Network Everywhere NH1005 5-port ethernet hub (it's not a router .. ?). Network Everywhere is apparently Linkseys' cheapie brand. Anyhow. I hooked up both my Dell and my new computer to it. Both browse the web just fine. However, Bittorrent and Limewire won't work. Someone told me I need to do some "port forwarding".

If it's of any concern, the hub thingie has six jacks: 1,2,3,4,5, and "uplink". I hooked up my cable modem to "uplink", my computer (the one using utorrent and limewire) to jack 1, and the Dell to jack 2. Both my comp and the Dell work fine on internet browsing, and some online gaming.

What need I do?

P.S.

This NH1005 is not listed on Portforward.com, someone already told me to go there. I don't know what port forwarding is, or how to do it.

A basic hub isn't capable of doing port forwarding. Port forwarding is basically telling a router that data on a specific port should be directed to a certain machine. So say you had a web server (Port 80) on one machine, you would configure your router to forward all requests for websites(port 80) to the IP address of the machine with the web server on it.

There may be a way to do it through internet connection sharing, but I've never played with that so no promises.

Also, does each machine on your network have it's own outside IP address, or do they start with 192.168. ? (start -> run -> cmd -> ipconifg) and.. don't post full IP addresses on a forum for your own sake

Since it's just a hub, it won't do port forwarding.
Your cable modem on the other hand MIGHT be able to do port forwarding.
What brand / model is it?

Also, are you getting two different IPs? (One for each computer?)

Limewire and Utorrent worked after a restart.

Ah, I'm glad I got a cheap hub then. To change the topic, can anyone explain to me the difference between a router and a network hub?

My old Linkseys router (it was smashed, long story) had four ports, a "WAN" port and an "uplink" port. The four ports were computers, "WAN" for for a cable modem, and I don't know what "uplink" was for, I know plugging my modem into uplink made it work sometimes, erratically, but was still "wrong". This hub has five ports and an "uplink" port. Does the cable modem plug into the "uplink" port or "1" or "5" or what? It's in the uplink and it does work, but kind of slowly. And my friend Steve said Hubs are bad for LAN parties because of packet interference or something.

Buy a cheap router with an inbuilt switch. They are dirt cheap nowadays. After you've got one we can help you set it up I'm suprised your set up is working what IP address is each machine?
some people answered before I finished lol
Routers keep tables of destinations and route traffic to the right place they connect lans. Hubs allow several PC's to share a connection traffic is bounced to all ports asking is this packet for you? Switches are like hubs but they remember who lives on what port and deliver packets to that connection. that the laymans guide You must have a different IP address on each of your PC's
Uplink allows you to daisy chain hubs

A router handles internet connection sharing, things such as DHCP, routing, packet filtering, quality of service, port forwarding, etc. It's basically a computer in a box vs a hub which is a simple data packet relay.

Hubs can induce lag on lans since the data is sent to all ports and the machines pick out the data that is theirs. An ethernet -switch- on the otherhand performs the same function as a hub, but is more efficient at it because it sends the data directly to the port that the target computer is on, not all of them.

If you can tell us the first two parts of the address on each machine it'd be easier to help you with your problems. If you're addresses start with 192.168 or 10.0 they are internal addresses, so your cable modem may be capable of providing router services.

PS: Uplink is a standard network port, but it's an auto-crossover port, so if you're connecting a hub to a hub it will still connect. Also, when people have a cable modem connected directly to a PC, they use a crossover cable. The auto-crossover/uplink port allows them to plug a cable modem into their new hub without worrying about changing the cable.

Generally use an Uplink port to connect hubs to switches to routers etc...
