Here are some more info: The default gateway of my Dell's NIC is blank. It is left black because my Dell has another interface, which is 192.168.1.100. This interface's default gateway points to my NAT server (for Internet access) which is 192.168.1.1. On my IBM, the default gateway of my NIC (192.168.2.100) is 192.168.2.1.
So, the setup looks like this: NAT(1.1)---Dell NIC1(1.100)||Dell NIC2(2.1)---switch-----IBM NIC(2.100).
Seems to me like when you have two machines that are on the same network as indicated by their IP and subnet mask. You hook them via a simple switch, then you should be able to ping and communicate, but this is not happening. I have no idea at this point why that is. Maybe I am missing something here.
Can somehow please tell me how to troubleshoot this? Any advice here would be great. I just can’t think of anything at this point.
