Old PC into a mobile broadband router

[RustyNailz]

Is there a way to turn my old PC (P4 3.0GHz, 1GB RAM, 40GB HDD) into a Mobile Broadband Router using my Verizon 4G USB device? (like a CardlePoint router)

I am searching some of the "PC to Router" software titles, but I am unable to find my type of setup: (support USB 4G as internet source)
DD-WRT, ClearOS, ZeroShell, RouterOS, Untangle, etc.

Design:
-use my Verizon USB 4G device as my internet source
-have a single NIC on my PC router plugged into a switch
-all my other PCs would be plugged into the same switch

Any help would be greatly appreciated!

ICS should work but it tends to be flaky sometimes....it was designed to share dialup modems. As long as your PC OS is new enough to accept the driver for 4g device it should work fine.

Thanks Bill001g, but I was hoping for a "better" solution than ICS as I would assume there would be a bottleneck caused by ICS with other clients on the network. I have read the throughput is greatly reduced for clients connecting to the ICS PC.
