sharing internet connection

[jmiller]

i have a cable modem, and i'd like to be able to share that connection between two computers. i was wondering if i could plug the cable modem into an ethernet hub and then plug both the computers into the hub as well. it's possible to do this in dorm rooms, where ethernet comes out of the wall, and since my modem has an ethernet jack i was wondering if it would work similarly.

thanks,
jmiller

just get a router. plug the cable modem into the WAN, then plug the computers into the ethernet ports. also, why havent you responded to my PM! this is travis by the way. cya.

hey check out my newbie webbrowser that i made. its still in beta, cause there are some bugs that i need to fix, but for the most part, its kinda done. my friend kows and i are going to put together a multimedia package. let me know if your interested in doing some coding for us jeremey.

uh... sorry dude but yuck

And what is the point of making your own? Since you're using VB, and from looking at your code, you use microsoft's rendering engine for webpages so you're just basically re-inventing IE.

Not much point to it..... but whatever...

meh.....

I just don't like it when people use the IE rendering engine for their browsers, since it's so horrible

Getting back to the original topic:

I would go for a router, there the best for sharing the internet and they also secure your computers. That combined with a sofwtware firewall will help control people who like to snoop or hack.

[datwig]

How about us who are on a peer-to-peer network that has a 56k dial-up modem connection? How would I share my internet with... myself? Do I need to download a program to set up a "proxy" or something?

I would have started a new thread for this but this post seems near enough:-

Me and some friends are going to get a house in the summer, we are going to get a broadband internet connection that comes into the house with a cable modem that has a lan port on the back.

I was wondering, since more than one of us are keen online gamers will there be any issues, I have absolutely no intention what so ever of paying any ISP extra money just to assign us more than one IP.

Presumably we will get one static IP and I will share the connection through a router with built in switch. (I already have a linksys router with build in 8-port switch so if I can use that I wont have to spend anything more)

My appologies for the rambling but my basic question is this. If one (or more) of us are playing a game with people (who are outside our LAN) over the internet, will the router know which computer it needs to direct each incoming packet too?

Im guessing that each computer should have no problems establishing an outgoing connection and that once this connection is established, winsock or whatever, then incoming data over the same connection should get to the right place. But what if one computer is just listening on a port? will incoming connections to that port get to the right place?

I suppose the same applies to web/ftp etc servers, if there is one running behind the switch router will it still be visible? I guess things get really screwy if more than one computer tries to host the same service.

Regards,

Tim.

ok sharing dial up exp:
right click my network places...properties
right click Local Area Connection...properties
click on the "advanced" tab
enable "share my internet connection"
click ok

Now plug your phone cable into your modem then plug a Cat5 into your PC and the first slot on the router(or WAN if applicable).

Now users will only be able to connect to the internet when you(server) is "dialed in" to the internet.

Now why you would want to share a 56K connection is beyond me but there is a rough illustration of how to do it.

[MixMaster]

That didnt really answer my question and its not dial up

[cid]

What was your question?

[MixMaster]

If I link some pc's to a router which is connected to a broadband connection with a static IP address, will everyone behind the router still be able to play multiplayer games over the internet? Will the router know where to send each incoming packet?

Yes you should be, the router knows the internal IP of each machine behind it, so it can redirect any pactets to the target machine.

[cid]

yes...Danial is right the router will determine what packets to filter determining on where they came from. So all out going packets coming from internal machines will not be filtered. Certain packets from outside machines will be filtered. So if you are behind a router than you should be able to play games fine but if you use a proxy than that is a different story.

You can't plug a DHCP cable modem in to a hub.

Here's the setup you'll need:

Server OR Router

2 x Network cards or 1 x network card and 1 x USB connection (depending how your cable modem connects)

You need to plug the cable modem in to one machine via 1 network card or USB socket.

Then plug an RJ45 cable into the other network card. This cable goes from your system to the hub. Plug all other systems in to the hub, making sure you assign different static IP's each time of course

So basically...

Server:
IP: 10.0.0.1
Subnet: 255.0.0.0
DNS: Leave blank if your ISP provides this automatically

Client 1:
IP: 10.0.0.2
Subnet: 255.0.0.0
DNS: 10.0.0.1

Client 2:
IP: 10.0.0.3
Subnet: 255.0.0.0
DNS: 10.0.0.1

and so on...

If you are using windows, then you'll need to enable ICS (Internet Connection Sharing). Do this by right clicking the INTERNET connection and clicking properties. The far right tab will have "Allow other users to connect to the internet via this PC" or other variant depending on your OS.

Check that box, and click OK. ICS uses LSASS.exe to probe other systems using 192.168.x.x addresses, not 10.0.x.x so you'll need to change the internal network connection back to 10.0.0.1.

If you are running Linux, then you'll need something like shorewall to configure the network. This is far harder, and you do not get the benefit of a GUI. Shorewall is a very powerful firewall, which also allows NAT (network address translation) and MASQ (Masquerading) of internal packets to external NICs. If you need help setting that up, please PM me.

Be sure all the systems are on the same workgroup too... or getting file access will be a pain!

hey you could do that or do things the smart way and spend 15$ instead of 100$+!!!
VisionIT that is one of the most prolonged messages for something so simple. If he would have done it your way he would be out a lot of cash. You notice that he said he only wants to connect two computers!!!!




One word:
CROSSOVER CABLE(CAT5e-RJ45)

Unless the cable modem in particular also happens to be a router (which I highly doubt), then VisionIT is correct. One must then route packets, via either a hardware router or a software router (i.e. windows server w/2 NICs).


And regarding MixMaster's post : Yes it is possible. Buy a "broadband router". Plug the cable modem into the WAN port on it, and then your computers into the ethernet ports. If you want to use a wireless network, then also put a wireless access point into one of the ethernet ports.

Your router will be using NAT (Network Address Translation) which translates the WAN IP into LAN IPs. The only problem you will have is data coming into your network that's not coming back on an already establish outbound TCP connection.
You will need to setup port forwarding, or, depending on the router, turn on particular TCP ports for games.

You will not need any software firewalls because your router is using NAT - i.e. no inbound connections are possible (except game ones).
You would only need a firewall if you wanted control of outbound TCP connections - which is completely irrelevant if you keep your A/V s/w up to date and your system patched.

One word? Maths not your strong point then?

You can do it via crossover cable, but you still need to enable ICS as I said before.

It's been a while since I've used crossover... my mobo auto-terminates the signal if it detects a straight-through cable!

Standard RJ45:
568A to 568A
568B to 568B

Cross-over RJ45:
568A to 568B

Cross-over cables should only be used whilst connecting two systems together, or joining hubs etc.

Getting a simple 4 port hub is cheap, and installing it is a doddle. Thats what I usually recommend to anyone setting up 2 PC's or more... simply because there's going to come a time where you'll need another RJ45 socket (for another system for instance) which then means either keeping the existing cross over setup and having it bridged with another network, or ripping it all out and doing what I said earlier.

Ok first off becauase the word is underlined constitues the fact that it is ONE(1) word....*scratching head* You guys didnt know that.

Ok, now pertaning to the post...most of the new cable and dsl modem are routers also. I just got dsl about 1 month ago and my dsl modem is a router also. And no i didnt have to pay extra for it. So depending on how long ago he got cable and depending on which package he picked depends on whether his cable modem does in fact have a router built in. So in theory of fact I can be(or am) correct. And VisionIT you are correct but i would research your cable modem and figure out if it has a built in rounter before investing in hardware. So before you buy a bunch of junk research and if you figure out that your modem has a router just get the crossover cable.

I'm not even going to start with you m8... you aint worth it!

If you have something productive to say, then reply... otherwise, keep it shut.

EDIT::

Intelsucks posted here earlier... but the post seems to have disappeared? I wonder if a mod removed it, or Intelsucks?

I happen to be a network administrator, so do not refer to my information as "junk research".
If you wish to respond to my statement, PM me. Do not post in this thread as your reply will be deleted.

And I want to reply in public so the people can see hitler agonize the jews(me)...Go ahead and delete the post Gestapo!!! And you should have PM'ed me instead of taking thread space!

No offence m8, so don't flame me... but I don't think PlenderJ was trying to impress you. He simply pointed out you had no grounds for which to call his research 'junk'. I fail to see how your age makes any difference to your knowledge though... i'm only 19, and even I show respect for people's opinion! If you disagree, thats fine... calling it 'junk' is simply a childish comment, and worthy of your age.

You remember what happened to the last person that insulted forum members, don't you?

[cid]

First off i did not say his research was junk...He took it that way and it made me mad so I "flaimed" him. If he would have read it correctly it would have came out like this...

Before you buy a bunch of junk,(forgot the comma) research and if you figure out that your modem has a router just get the crossover cable.

So I was telling him that before he spends money just figure out if he has a router built in to his dsl modem so he doesnt have to buy a bunch of stuff all he has to do is take 15$ and buy a crossover cablbe. So that way he saves time and money...

[cid]

Sorry plenderj im was just blowing off steam...sorry about the nazi comments. You just accidentally read it wrong or something. Please dont ban me. I would edit out the nazi comments but i fell that was sometime.

Forget the comma there too?

[cid]

No i didnt forget the comma. I posted that after he got mad. I posted that to fuel the argument and make things interesting...Now VisionIT you are trying to pick fights and suck up to the admins. I have already appologized so you need to forget about it and get your lips off plenderj's anus.

[IntelSucks]

hahahahahhaahhahahahahahahahhahahahahahahahhalips off his anushahahahahahahahahahahha thats great

[crptcblade]

I'm in love with each and every one of you.

[VisionIT]

You two are as bad as each other

I'm not trying to fuel an argument, but why not say you're sorry rather than try to backtrack claiming you'de forgotten the comma? You must think we're all stupid!

I'm not sucking up to anyone, i'm just sick of people having a go at each other and at the admins. You seem to have forgotten the terms of use policy and respect come to think of it...

I wouldn't put up with half the crap these admins do... so i'de count your blessings if I were you. I think they've been bloody patient considering the amount of crap been posted these past few months... now they've already delt with one ignorant little brat, and you pair are going the right way to following him.

Intelsucks: If you can't stand me and you feel you need to tell me, then PM me instead of wasting everyones time here. Keep your immature comments to yourself otherwise.

I already know what your gonna say in your reply. "Your immature, stop wasting board space, Im a queer." Yes you are.

You are an immensely childish stuck up little prat. Is there any one that actually likes you? By that I mean do you have any real friends, I dont count all your bigot friends on here.

Also, just to say thanks to plenderj , your post about incoming connections about through a switch/router thingy has been very helpful.

[VisionIT]

Now i'm confused!!!

Who keeps deleting IntelSucks posts? Mixmaster's quoted him, but his post has gone... who removed it?

I'm not going to comment on what he said, cause Mixmasters pretty much hit the nail of the head!

Danke

[cid]

1. Or your as typical as everyone else...

I'm not trying to fuel an argument, but why not say you're sorry rather than try to backtrack claiming you'de forgotten the comma? You must think we're all stupid!

2. Yes you are trying to fuel the argument, that is the whole presidence over these arguments, if you really were a peace lover you would have pm'ed me instead of posting publically. Now if you look at what i said originally:

So before you buy a bunch of junk research and if you figure out that your modem has a router just get the crossover cable.

There is no way that this sentence could have made any sence without the comma. You would have to be an ignorant fool to think otherwise. Now visionIT read the sentence with the comma:

So before you buy a bunch of junk, research and if you figure out that your modem has a router just get the crossover cable.

If you read it, it speaks nothing of plenderj's research!!!

I wouldn't put up with half the crap these admins do... so i'de count your blessings if I were you. I think they've been bloody patient considering the amount of crap been posted these past few months... now they've already delt with one ignorant little brat, and you pair are going the right way to following him.

3. Well i guess we are lucky your not an admin.

Intelsucks: If you can't stand me and you feel you need to tell me, then PM me instead of wasting everyones time here. Keep your immature comments to yourself otherwise.

Actually you should have pm'ed him instead of posting like that. See, you only want fights!!!!

So in conclusion...
VisionIT only wants to se a good fight. He doesnt know how to react to an appology when he sees one. He also cant get his lips off the admins rear-ends...I think it is called BrownNosedaphobia. VisionIT you need to grow up and learn to accept what you are instead of using this website as a crutch to compensate for real life.

There's probably a reason... can anyone think what it could be?

If you guys would actually know anything about grammar and the english language, you could tell by how this sentence sounds that a part of it was missing (A comma?). VisionIT if you were to read the sentence in the right context you would see the sentence correctly.

See the funny thing is if a kid named Dill_Pickle understood me why cant you guys...?
