internet sharing without autodetecting ips.

justakid · 4th July 2001, 8:51 PM

Hey all, I was wandering if anyone could tell me if it was possible to share a modem connection, but rather than having 192.168.0.1 for the dialup machine and having the rest of the machines set to autodetect... is there a prog that allows u to set the pcs to a specific ip and use 192.168.0.1 or what ever as the was to the internet?

thanks for any replies.

welllll
its a bit of a long procedure to setup and not exactly straightforward. but you have to keep 192.168.0.1 as the modem machine.

First thing you do is run up winipcfg on the machine with the modem while it is connected to the net. Press the button to give you more info, and take down the DNS servers info

Next, go to one of the client machines, go to its TCP/IP properties, and assign the machine an IP such as 192.168.0.2

While there, enter in the DNS servers you took down from winipcfg, and set the gateway as 192.168.0.1.

Do the same for any other client machines on the network, numbering their IP addresses uniquely.

EDIT: Sorry, this is assuming you're using Win9X/Win2K ICS.

As long as you set the gateway/dns as the server (192.168.0.1) you can specifiy the IP's of the other PC's as static...

Works for me both under Sygate & ICS (W2K)...

Yes, you need to set clients up so that DNS and Gateway are pointed at the ICS Internet connected machine.

ICS acts as a DNS server and also can act as DHCP server, but if you're manually configuring IP's on clients then that DHCP component is taken out.

so i just set teh gateway and DNS of the tcp/ip protocol for the network cards on the client machines to 192.168.0.1? i dont have to find out what my DNS is when im online and use that for the DNS like sabre said?

When you enable ICS on your machine that will be sharing the Internet connection, your network card connected to your internal LAN will automatically be assigned an IP address of 192.168.0.1. This is hard coded into ICS - if you try to change it, don't expect ICS to work.

Enabling ICS also makes your Internet connected PC act as a DHCP server on your internal LAN, and a DNS proxy for you internal LAN. You then have 2 choices with your "clients":

1. You can tell them to obtain their IP settings through DHCP - this will configure IP address, subnet mask, default gateway, DNS entries, etc.

2. You can configure their IP address manually. You need to give them an IP address in the 192.168.0.x range (1-254), with a subnet mask of 255.255.255.0, default gateway set to 192.168.0.1 and DNS set to 192.168.0.1. Be aware that your ICS service does NOT act as a web proxy - so telling your browser on the client machines to use 192.168.0.1 as a proxy will *not* work unless you also run a proxy service on the box which is sharing your Internet connection (might be a good idea for people who are sharing a BigPond account, to try cut down on traffic).

Most games, ICQ, etc will run through ICS transparently, so there's very little else you need to set up.

You're IP address to the internet is given to you from a DHCP server that you dial into

you do not need to worry about this.
(if you want to find this just goto Start\run type winipcfg )

There are a few ways of achieving what you want , for example if you really don't want to use 192.168.0.x as your network address , you must replace ICS with a 3rd party software item.

I use Winroute Pro , which has a slew of other features that are quite handy but you will probably not use.

What benefits does this give me ???.

Well winroute pro ( also winroute lite) not only do all of your internet sharring , it also incorporates a mail server (internat as well as lan) , a proxy server , a full DNS server and a DHCP (Dynamic host control protocol). Winroute also incorporates an awesome firewall as well

.

The pro version is fairly expensive but the lite version is a lot cheaper (no mail server etc) .

This will let you use any IP address you like ( I use 10.0.0.x ) , it will also let you determine what packets get to the net or come in from the net (or on your network) through the NAT router (Network address translation).

What is a NAT router ???? , what is IP masquerading ???.

When NAT is used with computers located within a local area network they do not use Internet registered addresses. They use the internal IP addresses. This hides the entire network behind a NAT, making it look like a single computer with a single IP address. This IP address does not have to be statically assigned. The computer can be given an IP address dynamically from your ISP each time it logs on to the Internet.

Phew a bit long in the tooth but I hope I have helped ??

I have tried to explain why NAT makes a very good system to share internet connections (Win2k server has this). I am not sure if ICS supports this , but I am certain that ir doesn't support any form of secruity features ( port mapping for example).

So to answer your question yes there is software available
