Everything I try seems to produce unwanted results. My situation is this: I want the people on the Intranet (192.168.100/24) to be able to telnet to the server, but everyone else sholud be denied. I hope I'm being clear in this. I've tried a few o/ifilters with no real luck. I always seem to block ALL telnet requests, or allow all of them. Oh, and everything else should be allowed to pass normally. I have some filters up to prevent ICMP keep-alive, and dial, and they work fine. Thanks. Joe Clarke
