Denying TCP connections based on IP

We have a firewall but I would like to add another layer of security to our
system (AS/400, iSeries, i5, System i, etc.). I would like to specify a couple
of IP ranges on the system and only allow connections from those addresses.
Any other IP address that attempts to connect to the system would be denied.
This would be at the interface level and include all services since our system
is not on the internet. All suggestions will be appreciated.

Thanks.
