Adding Cable Modem to a Frame Relay Network

If anyone has any knowledge on how I can make my cable modem accessible on my office network please feel free to share. Some specifics.
I have a Frame Relay WAN with a private IP(10.35.xx.1 on each router & 10.35.xx.2-255 on each client) have this IP in 18 offices. (So I need to keep that IP so I can see other offices and vice versa.) I have a cable modem and cannot get a client to have internet access AND network access. It seems to be one or the other. Right now I have a linksys router giving a few stand alone PCs internet access. I know there has to be a way. I tried several methods linksys seems to say will do it. But no luck. I cant be the only person trying this. Is there a way to plug this cable modem into my switch and perhaps add a gateway to clients I choose to have internet access. Without losing their Network access? And without adding a 2nd NIC.
Thank You in advance

One possibility: Nexland's dual WAN port router at http://www.nexland.com/products/product.cfm?id=4. I have no first-hand experience with Nexland products. Larry

I'd call them also and discuss what you are trying to do. Larry
