How do i share my ADSL line on my PC with my MAC (back to back)

Hi,

PhilHawks response seems pretty good. I just wanted to throw another option in. Well, its pretty much the same thing, but rather that using the MS crap ICS you could install a proxy server on your internet PC. Something like allegrosurf will allow you to use it at home for free I THINK.

You'll need another NIC in you Internet PC and connect that to the NIC on the MAC with a CROSSOVER cable.

This option could be used if the ICS option doesnt work.

Let us know what happens, good luck.

Pete.

Hi, pete clem + PhilHawks

Thanx for a pront reply.  

I have XP and i set up a connection using MS ICS, It looks like on the PC side everything is working correctly.  My housemate is still trying to establish exactly how to set up TCP/IP on his MAC, i guess once he has done that, we should be up and running.

Thanx again for the help:)

look in apple menu>control panels>TCP/IP setup.
if automatic configuration(DHCP) doesn`t work,
set the ICS pc address (usually 192.168.0.1) as the gateway, and the Macs Ip address to 192.168.0.2
You will alos need to add the DNS server address,it may work with the pc IP, or you may need to find out the ISP DNS server addresses.

(sorry if this is a little inaccurate, but it`s from memory

The DNS Server address should also be set to 192.168.0.1

As has been mentioned before you will have to connect the PC & the Mac with a Crossover cable (not just a standard CAT 5 Network cable)

This site explains how to set up a MAC as an ICS client:

http://www.practicallynetworked.com/sharing/

The DNS server doesnt need to be set up in the MAC at all guys...

and if you set up the IP address (hard wire it) then ICS WONT work...   this is because ICS acts as a DHCP server for the sharing PC's.

One thing though... BrunoC...  have you been given a static IP address by your ISP (internet service provider) ?

If not I expect you have the PC set to DHCP too.  if so... leave it as it is and then set the MAC to DHCP too.

The Proxy server is a good last option.  This is because it it will be ALWAYS running as a service and also the internet can take a bit of a slow down in speed.  

Let us know how your going.  

In fact... if you set up ANYTHING (i.e. IP address, DNS, anything except AUTO) on the iMAC then it wont see the internet....  so be carefull with the settings.  All the PC is doing is converting the internet data to the DHCP protocal and the iMAC is looking for that protocal.  This is NOT a TCPIP network you creating here.  Not a real one.  your using your PC as an interface/gateway to the iMAC.

Incidently...   dont set up the Gateway option on the MAC eather.  It doesnt need one.

Good luck

PhilHawks - you say that if you set the IP manually on a Mac ICS wont work.  I believe you advice to be incorrect.  The information I have tells me that you MUST set the IP configuration on the Mac manually - http://www.practicallynetworked.com/sharing/mactcp.htm

>>All the PC is doing is converting the data to the DHCP protocal and the iMac is looking for that.... - This statement is incorrect. DHCP is not a protocol, its a service - no data is sent via DHCP it is used only for allocating IP addresses. When you have a Mac client with a windows machine as an ICS host, it is a TCP/IP network and all communication is done over TCP/IP.  

Check the information here for Mac acting as an ICS client with a Windows machine as a host - http://www.practicallynetworked.com/sharing/macnpc.htm 

Well, I run a shared mac/windoze/linux network, and my macs had to have the gateway set.(might be because it`s a linux dhcp server).
We also use samba/netatalk for mac/pc filesharing.
all works well.

Yeah, you will need a default gateway if you have a router set up on the edge of your network. Basically, the computer will pass data on to the default gateway if requests cant be delivered locally. This is more complex and doesnt need to be set in this case. If you want basic web browsing from the Mac then you only need to set the browser up to forward its requests onto your Internet PC (it will either be running ICS - basically a MS embeded proxy or 3rd Party proxy software, such as Allegro surf)

If both machines are using TCP/IP as their network protocol then it very much is a TCP/IP network, even between 2 Computers.

Basically, set the LAN ip of your Windows box to 192.168.0.1 with a netmask of 255.255.255.0. Set the Mac IP address to 192.168.0.2 netmask 255.255.255.0. Leave DNS settings and gateway settings on the Mac alone. DNS requests will get processed by you Windows box that is running the proxy software (ICS and 3rd party software is proxy software). Set your web browsers proxy settings to 192.168.0.1 on the Mac. Leave the settings on you Win box alone as this can communicate directly with the web as it has the ADSL connection locally.

Hey presto it may work. I say "may work" because in my experience, if your not using an all windows network then ICS is a pile of crap (come to think of it, ICS is a pile of crap full stop.) So i would install allegro surf and run that.

Hopefully this has recapped what has already been said here. But BrunoC hasnt posted back recently, so lets us know whats happening.

Laters.

hi,

I have been reading all of your replies and have been trying all of your suggestions.  some with no lucka and some with some luck.  Needless to say i have now got it working, the MAC is using the PC as a router to connect.

I tryed everything and got more and more p**ed at it.  jus as i was about to give up, i started entering the PC's ip in the proxies on the mac, just as i was about to give up and disconnect i tryed to run explorer, and would you beleive it! it worked:)  I am still not 100% sure how it worked, but it did!

This is how it worked in the end

Win XP PC:
1. IP: 192.168.0.1
2. netmask: 255.255.255.1

Mac (OS X 10.2) settings:
1. Using Manual DHCP with ip address
2. IP: 192.168.0.2
3. netmask: 255.255.255.1
4. Router: 192.168.0.1
5. Proxies: streaming proxy: 192.168.0.1

I am sure that these are the correct final settings on both machines, that did it:)  If any of you would like me to double check the settings for your future knowledge i would be happy to.

Thanx for all the help.  experts exchange is by fare the best forum i have i ever come accross.

BrunoC,

Perfect, yipee and all that. Settings look exactly correct. Its a pi**er, but great when something finally works :-)

Nice one, I did run a mac at home for a while on a windows 98 ICS setup, but found it too unreliable(win98,not the mac).
I no longer personally use windows or mac at home, but there is a mixture of windows and linux at any given time(the mac was borrowed to learn the os).
At work, my network consists of 3 different flavors of Linux, windows 98,NT4,2000,XP, and several mac os 9.

Petclem, the point I was making was that even though my dhcp server dishes out default gateway and dns addresses, the macs fail to pick up the gateway.
