Internet connection sharing

galwaydude18

I have a latop that is networked using a switch to my desktop. Im using windows xp pro sp2. The problem is that i can not get internet connection sharing to work. I can ping both machines both ways. I do not have any firewall or antivirus setup on either machine at the mo. i use the desktop to connect to the net. any ideas on how to get this to work?!!

galwaydude18

anyone have any idea on this? I need to get it working before I go back to college tomorrow afternoon!

More details.. How is the desktop connected to the net? Are you sure the SP2 firewall is disabled? (It's on by default).

galwaydude18

The desktop is connected to the net via a dial up connection! sorry for leaving that out! yes the sp2 firewall is disabled!

galwaydude18

sorry lads! i know ye all hate this! bumping up etc. but does anyone out there have any ideas? i really need to get this working before tomorrow afternoon!

Run the Home Network Wizard and select the desktop as the internet gateway and the laptop as a computer on the network and connect to the internet through a gateway on the network.

Then make sure that in your internet connection properties that your allowing other computers to connect through the desktops internet connection

Let me think now...

Main PC connected via Dialup.
Second PC connecting to main PC via ethernet switch.

So, what i did in my setup (which is exactly the same for all intents and purposes) is disable windows built in ICS and installed Kerio Winroute Firewall. Then ran the configuration wizard, and had the sharing working within minutes. Unfortunately it ain't a free app, but its worth a shot.

I've never dabbled with windows' ICS. I've heard bad things about it. It can be a bitch to get working.

dempsey i just tried that and it made no difference at all!

Hmmm, weird, Thats all I needed to do for my network. What protocols have you installed on both pcs for the network and internet?

galwaydude18

iv got installed on both machines!
Client for ms networks,
service advertisin protocol,
file and printer sharing,
QoS packet schedular,
NWlink netbios,
NWlink ipx/spx/netbios,
internet protocol (TCP/IP)

Mutant_Fruit

have you set the two PC's to the same subnet mask?

I.e. pc 1 (main pc) should have:
IP 195.168.0.1
Subnet: 255.255.0.0

PC2:
IP: 195.168.0.2
Subnet: 255.255.0.0
Gateway address (And dns address): 195.168.0.1

ok just tryin that Mutant Fruit! il get back to you in a minute!

galwaydude18

nope that didnt work when i entered in that info! by pc2 did you mean the laptop?

Dempsey

What does the laptop do when you try to get up a webpage on it?

Mutant_Fruit

pc2 is the laptop.

Ok, well i can't help any more other than suggesting you use Kerio Winroute firewall, with those settings. That would be my setup exactly. Except i have broadband, not dialup :P

say if i try to go to www.google.com it says opening page http://www.google.com
It then goes about two bars and then i get the "The page cannot be displayed" error

Set the IP of your main PC to 192.168.0.1 and the other pc to 192.168.0.2 and the subnet mask on both of them to 255.255.255.0.

Run the ICS wizard on the main machine again, but don't use the create floppy disk part.

Remove NWlink netbios and NWlink ipx/spx/netbios from both computers.

Now on the second computer set the Default Gateway to 192.168.0.1 and presto (hopefully)!!!

On your laptop, 2nd PC, You shouldn't be using the desktop pc's IP as DNS, you should be using your isp's. Try 159.134.237.6 eircoms main dns server. You should be able to get the details for your ISP from the web.
