1 modem, 2 computers on a LAN - dial out for both?

[Bazango]

I have two computers on a LAN that communicate OK, but I would like to access the internet using the computer that is not connected directly to the internet. How do I do that? Using the modemless computer, I get errors when I try to access web sites.

It seems like if I set up the modem computer as a gateway, I can ping a remote host using an IP address only, if I use the URL, I get error messages. Is it a DNS issue?

What is the procedure for hooking up to the internet using a 56K dial-up connection from a LAN? I have no permanant IP number, I hook up using DHCP.

You need to install an internet sharing program to do that. There are a few out there like Sygate or Wingate. They cost though..if you have win98SE installed..you could try the built in sharing software called ICS ..

Here's a good link that expands on what smokin1 was speaking of... http://www.practicallynetworked.com/sharing/sharing.htm

3com makes a very inexpensive lanmodem which can handle up to 25 users. Not that this will help your problem...just thought I'd mention it.

So why isn't it possible to make the connection just with the software installed for TCP/IP?

In layman's terms..the machine without the modem needs software to convince the machine with the modem to allow it to use it and share/play nicely. A lan connection is a different thing all together from sharing out to the net.

This summarizes it pretty well...

http://www.linuxdoc.org/HOWTO/PPP-HOWTO/c112.html

If you have a LAN for which you have not been allocated IP numbers by the responsible authority in your country, you should use one of the network numbers from the above sequences for your machines.

These numbers should never be used on the Internet.

However, they can be used for the local Ethernet on a machine that is connecting to the Internet. This is because IP numbers are actually allocated to a network interface, not to a computer. So whilst your Ethernet interface may use 10.0.0.1 (for example), when you hook onto the Internet using PPP, your PPP interface will be given another (and valid) IP number by the server. Your PC will have Internet connectivity, but the other computers on your LAN will not.

The numbers they are talking about above are,

...IP numbers that are specifically dedicated to LANs that do not connect to the Internet.

I use these numbers on my LAN. Communications on the internet are two way by definition. If I want to contact a real address on the internet, I have to have a real address myself.

My ISPs have always been like most ISPs, they provide me with a dynamic IP number assignment. I can get a permenant IP number, but that is additional obligation to my ISP and the internet at large. If I add a LAN, even just one computer, that is an additional burden as well.
