sshd uses tcp wrappers on CentOS/RHEL. Use /etc/hosts.allow and /etc/hosts.deny

/etc/hosts.allow should have the IP range to allow:
Code:
sshd: 192.168.0.

This allows all hosts o nthe 192.168.0. subnet as an example

/etc/hosts.deny should have this entry:
Code:
sshd: ALL

This denies anyone who isn't defined in hosts.allow
