Cisco 2960G setting up a Vlan to grab 2 public ip's from modem?

Hi guys,

     I am looking to use ports 1-3 in a Vlan to grab 2 public ip's from a cable modem.  So, for example, the cable modem would be plugged into port 1 and the other devices plugged into port 2 and port 3.  Because the cable modem only has one port, I need the switch to grab 2 public ip's from it.  Does anyone have a simple example to guide me?

Thanks for everyone's help.

Jason

You really just need to have those ports in the same VLAN. As for receiving 2 DHCP leases you need to make sure your ISP is allowing you to receive 2 leases on your network. It wouldn't be recommended that your layer 3 management interface for the switch itself is in this "public" VLAN.
