It isn't so much the version as the feature set.  You currently have the "ÏP Base" feature set and need at least the "Advanced IP Security" feature set for firewall functionality.  This will require that you purchase the upgrade license for the new feature set if you don't have it already.
If those are what you need then you need to get the Advanced Security version of the IOS.  You will need to purchase an upgrade for this if you purchased the router with IPBase.
If you have a CCO account there is a code selection/feature matrix for pretty much any model. Make sure that you have sufficient bootflash and memory for the new code.

You can access the Cisco Feature Navigator at http://tools.cisco.com/ITDIT/ISTMAIN/servlet/index and select whichever features you need for any particular platform.  It will then provide a list of all IOS images that support the selected features.
