using nat

Hi,
I do want to use nat. I have a win2000 setup up as a workgroup and networked to a win98.I thought I set up nat correctly, but it seems not to be working. I do want the win98 to be able to dial out on the win2000 and have internet access.How should I set up the win98 to see the win2000 and to have it dialup? Is there any way to check to see if I have nat setup correctly.I have a internal modem hooked up to the win2000. My isp is a free based internet access(bluelight).Any suggestions would be helpful.If I could correspond w/someone through their e-mail it would be a great help…I’m stumpped and I do need to have this implemented asap. Thank’s in advance………. But I do want to use nat for this.
