Computer-2-Computer Networking

[DanM602]

Hi,

I have a crossover cable connecting 2 computers. The Primary computer has another NIC that is connected to AT&TBI Cable Internet.

The other computer has internet and all but it can't see the primary computer shares so I can't access the drives and stuff. I had to assign a AT&TBI ip to the machine for it to be able to go online but is there any I can set this up so I can see the shares and also go online.

I am also having the problem that when I wanna play unreal online i can only have one computer online. I think this is because the primary ip is shared between pcs and it can only be used for one program at once. Please correct me if I am wrong and if anyone has any info on this let me know.

Dan

Please post more information including:

Operating System

Method of connection sharing (running a proxy, router, ICS, etc.)

Using static IPs, DHCP, etc.

With that info I think we can help you better.

Operating System - Windows XP Pro

Method of connection sharing: The Internet is shared with Windows XP's Internet Connection Sharing but I also have Sygate Office Networking if that helps any.

The Internet IP is DHCP Assigned by AT&TBI. At the moment the 2 NICs that are connected together via crossover cable are each statically assigned an AT&TBI ip but i would like to get around this but have shares and internet still work.

The problem is that you want to give the NIC on the private LAN side a private address not an Internet IP, you want something like 192.168.0.1 as well as a private IP on the 2nd machine. This will also fix the problem with your shares not working.

EDIT: Set 2nd machine to use DHCP as it should get an IP from the machine running ICS.

I tried that they were both 169 IP's but my internet wouldnt work on that machine

169.x.x.x means that the computer is not receiving an IP address fomr the DHCP server. Look into your DHCP service.

169 IPs are APIPA IPs. If you set the 2nd machine to use DHCP it should work.

[DanM602]

yea i know that they both assign 169 ips and i also have that sygate proggy where i can control everything but if i dont statically assign 24.60.*.* ips the other machine wont go online

[ahodes1]

You are assigning DNS server and default gateway info aren't you?

[DanM602]

yep for the att i am

[ahodes1]

I mean on the 2nd machine, the default gateway should be the IP of the NIC of the 1st PC on the local side.

you have a static ip with your isp?

[hotrod]

which NIC did you tell XP that you wanted to share?

Hi all,

Just asking if u guys can help me with this...

I am on BT Broadband at the moment and they're on a Non-Nat system. I am connected to them via an Alcatel ADSL USB modem.

The thing is..I am also connected to 5 other computers in my house via LAN and a network hub and i desperately need advice as to how i can enable ICS on the other pc and direct them to point to my pc as the Internet gateway out...

Now, BT says that I can only connect to one pc using their connection but I am of the opinion that ICS is possible if done correctly...so I would really appreciate it if any one can help me out in this..

Many thanks.

Eric, first of all you will need to have every nic set to uptain an ip automatically.. ALL of them. on your desktop, right click on My Network Places and choose properties. you should see the Alcatel modem there. right click on it and choos properties also. look for the sharing tab or whatever it may be under depending on your OS, enable sharing for the USB Alcatel modem. i would then reboot that pc. now for your other pc's if you set them to obtain an ip automattically, you should be able to reboot them and obtain an ip from the machine running ICS.

how do you have the pc with interent connected to the hub? is it connected to a regular port, upling, wan or anything similar?

[ericlims]

Thanks for the adive you've given...The thing is I have already set the rest of the workstations to obtain IP from my computer which serves as a DHCP server which btw, my computer is the one connected to the USB modem and is hosting the ICS service and as I have said previously, my computer connects to the other pc via a network hub. But BT has clearly stated in it's TOS that it will only connect to one computer...So anyone out there with similar predicament, pls. let me knowif you have a workaround to this problem..

Many thanks
