You need an IP PLUS image (you have an IP image) and unfortunately you would need to upgrade the DRAM and Flash depending on which image you were going to go with.  Looking at Cisco's site, you can't get an IP PLUS image that will work with your routers memory.

Please let me know from where i can get this . CISCO site is asking for username and password.
If possible please send to wils_john@hotmail.com
Well, as I said, the problem is that you can no longer get an image from Cisco that fits on your router.  You need to upgrade the RAM and Flash on the router to support a newer image that has the feature you need.
