Allow telnet in AIX from specific IP adds, but disable for everyone else

I need to change the security on our AIX servers and disable telnet from all but certain IP addresses.

I have hashed the telnet line in /etc/inetd.conf and added filter rules for those IP adds to allow access on port 23, but this didn't work.

Does anyone have any ideas?

Thanks.

telnetrc(4)							   File Formats 						       telnetrc(4)

NAME
telnetrc - file for telnet default options DESCRIPTION
The .telnetrc file contains commands that are executed when a connection is established on a per-host basis. Each line in the file con- tains a host name, one or more spaces or tabs, and a telnet(1) command. The host name, DEFAULT, matches all hosts. Lines beginning with the pound sign (#) are interpreted as comments and therefore ignored. telnet(1) commands are case-insensitive to the contents of the .telnetrc file. The .telnetrc file is retrieved from each user's HOME directory. EXAMPLES
Example 1: A sample file. In the following example, a .telnetrc file executes the telnet(1) command, toggle: weirdhost toggle crmod # Always export $PRINTER DEFAULT environ export PRINTER The lines in this file indicate that the toggle argument crmod, whose default value is "off" (or FALSE), should be enabled when connecting to the system weirdhost. In addition, the value of the environment variable PRINTER should be exported to all systems. In this case, the DEFAULT keyword is used in place of the host name. FILES
