Solved

Help. I need to share internet between two desktop computers WITHOUT a router or hub, using only a crossover cable.

I’ve been looking for days (over a week now) for a solution to my problem. What I want to do is this:

Share internet from Computer A to Computer B with only a crossover Ethernet cable. No router, no wired hub, just the cable. Both are Windows 7 computers.
I’ve had it set up this way for almost a year, but Computer A’s hard drive recently crashed and I’ve had to replace it with another computer and I lost the instructions that I used before to set it up like this. Here’s what I remember from those instructions, if this will help:

Computer A: (Internet connected PC): One of the ipv’s was set to an IP Address of 192.168.137.1

Computer B: One of the ipv’s was set to 1:2:3:4:5:6:7:8

And I remember having to go into Windows firewall and allow some connection. I think there was an issue with this as well where I had to go in to some settings to even make it show the option to allow the connection?

I think I may also have had to go into my broadband modem and make adjustments as well, cannot remember what I did there.

Someone might ask why I want this sort of setup. The reason is this: I cannot use my router because I connect to a VPN for work over Computer B, and the VPN will not allow me to connect with the model of router I have. Also, I don’t have time to go buy a wired hub even if that would work.

This seems like it would be easy for some of you gurus, so please can someone help me?

Thanks in advance.

    in network properties 'use allow this computer to share it's connection', you'll also need to set the gateway of the second machine to be the address of the first machine.

    I'm not sure what an ipv is, but you should enable DHCP on computer B (obtain IP address and DNS address automatically).
  3. I suspect "ipv" means either IPv4 (for "legacy" IP addresses like 192.168.1.2) or "IPv6" (for new-style IP addresses in the form of 0:ffff:4::5:6). But @Buddha is right, your ComputerB should be set either to manual IP address on the same network, or as DHCP client.
