How do i access the internet through a LAN

[WaNg_535]

Some of my friends are setting up a LAN but we can't access his
internet from anyother computer....
His internet is on DSL does this pose a problem???
If not how can we go about setting it up ????

[Ghost_Hacker]

The DSL line isn't a problem. What operating system does your friend use?
( the setup is different depending on what operating system you use)

Something that your friends should also consider is the Network Protocols that they will use. TCP/IP is the one that they should use if they want to share an internet connection. If your Friends are using Win98 Seccond edition on all the machines, microsoft offers a free program that allows you to share an internet connection; otherwise, you should add TCPIP to all the machines, making sure that the Subnet Mask is the same for all the machines (the most common is 255.255.0.0) and the IP adresses should be 192.254.0.1 changing the last mumber (.1) which should be one per machine.
Bare in mind that each group of numbers must only range from 0 to 255.

Hi

Wait .. r u saying that ur trying to set up a lan from this one dsl line to be used in a network with other (local) computer's??

There r alot of variables regarding dsl. Does ur friend have adsl, or sdsl??

I had sdsl and it had a dsl 'Pipe' router/modem (external) and it had a 'hub' plug-in on the back for 5 other pc's. Which could not be 'turned off'. )was always on.

I now have adsl and it goes thru a westall dsl infospeed ext modem and it can't be connected/shared w/ other pc's. This is not due to the modem type it id due to the connection type (adsl)
This has a 'turn-off' switch on the back and is connected thru a WinPoET/tcp-ip connection.

** additionally, go here (http://www.dslreports.com/) for just about anything regarding xdsl http://www.PCGuide.com/ubb/biggrin.gif

ok...so now what ??

Sorry Sea,

But what sets sdsl apart from adsl is downstream and upstream speeds. SDLS offers the same speed for both uploading and downloading. ADSL offers one speed for downloading and one for uploading. (the downloading speed is the faster of the 2).


The abilty to share a connection will depend on whats call a "NAT" (Network Address Translation). Simply this allows one computer to take many IP address on the "lan" side and map them to one or more IP address on the "wan" side. Actualy "map" is the wrong word what it does is take a packet and change the sending ip adrress from one on your network to the IP address on the External "internet" interface. To the "DSL line" all trafic is sent back to this one address. The computer runnning the "NAT" knows what packets to forward to which computer on the inside base on it's NAT table.

There are other ways of sharing internet connections but this is one of the common ones used with "internet sharing" software.

another important thing we did not mention was that adsl(asymetrical) is a dymamic IP, while sdsl uses a static IP.

some success has been reported (limited and w/ many problem) networking adsl (telco) lines; some success has been had useing Linksys routers, however- I am not saying it can't be done. I am saying that in order to do it, one must have the correct equipment, alot of patience (and knowledge of what one is doing) lol

**in any event (GH) we r in the dark to try and help, (unless this person posts back)

ok...so now what ??

Ummmm.....You really just need the right software. If you are using a static IP address than most software will work without extra setup. If you have a dymamic IP Address than the software may not work if it can't do "demand-dailing".

Of course you do need the knowledge to implement it but hey...that's what we geeks are here for. http://www.PCGuide.com/ubb/smile.gif

precisely as to my original question " Does ur friend have adsl or sdsl"

adsl is "Static", and sdsl is "Dynamic"

depending on the software if it is an adsl (static)IP-, then the question also becomes which software is he using (RASPPPOE, WinPoET) lalala

So if this Winpoet can't be disabled and is the only way to create the connection to the modem. Then the connection sharing software won't work.
So the trick is to see if Winpoet and it's clones can be disabled.


So how does Winpoet work on your machine?

Update--- From what I can tell winpoet is a dialer that logs you into the ISP's network. Is that how it works for you Sea? I know we're getting off topic but I just can't help myself.

Jeez guys, just connect a Linux machine to the Internet via whatever-the-h*ll-connection and use ipchains to forward to all the Win machines. This is the stuff that Linux was born to do... for free.

And you can do it with an old 486, set it up, it runs 24/7, never crashes, get with it!

Hehe...another Linux faithful http://www.PCGuide.com/ubb/smile.gif http://www.PCGuide.com/ubb/smile.gif

Yeah, I know how to do it with Windows programs. Don't know that much about Linux.

But I'm interested in this Winpoet since I've never run across it. It's a chance to add to my knowledge base.

WinPoET is a software app . It works like DUN ( a familiar interface for all)

It uses ur phone regular phone line to make a dsl connection (enables u to use PPPoE to connect)
also this app WinPoET uses (as the "WIN" name implies) very much like a "WinModem" uses ur system resorces.

Way around this is to "nuke" WinPoET and install RASSPPPoE, which does not use system resorces.

I have not done this yet I only can get a max of 711kbps so it isnt needed

Ok...So as long as there isn't a timeout feature like some ISDN interfaces have. Then once the connection is established you should be able to share it. Much the same way a Modem connection can be shared.

The only problem would be that only one computer could establish the initial connection.


Should work without to much fuss. But watch... the guy with the problem will never post back a reply and if he does he'll have windows 95.

Right click on it and you get the "Save picture" option. It's a picture posted into the reply. Probably drawn up in something like Paint or Paint Shop Pro.

Sleep....noooo wayyyy.....ZZZZZZZZZZZZZZZ.....Huh?What?Oh..sorry you caught me napping again.


Yeah, I took a look at the site. It's got some good info. When I get a chance I'm going to read the horror stories. The PacBell one has got to be good.
