Are you using an etherswitch module in the router? Most of not all modules support port security, and will limit devices based on mac address. Here is a gude for configuring port security. It is for a 6500 switch. but all the commands are the same.

Thank you Mark. No modules in the router - just the 4 LAN ports. Because other people have access to my client's network equipment I need to restrict physical access to the ports.

I tried the port security command already and it's not recognized. The IOS version is 12.3(7)T1. Could it be an IOS issue?

Unfortunately I am not seeing any documentation that shows that the router supports port security. I also looked at the feature navigator and didn't see it supported in the IOS either. If port security is a necessity I would recommend a catalyst switch to plug your users into.
