Share USB aircard with multiple PCs

I am currently living in Kuwait and they use USB aircards to get on the internet. The aircard is shown as a dialup connection under network management. Anyway, I'd like to be share this with multiple PCs using my linksys wireless G router and a computer acting as the HOST PC. I tried using Internet connection sharing but that didn't work. I've pasted the IP settings when the aircard is plugged into a computer. All computers use Vista Home Premium. I appreciate the help and let me know if further info is needed.
