(usr-tc) Filter wildcards

I'd like to construct a filter that will stop attempts to send traffic to broadcast and subnet addresses of class C's. In other words *.*.*.0 and *.*.*.255. Any good ideas on this? I don't recall if the TC has any provision for wildcards in filters. - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message. For information on digests or retrieving files and old messages send "help" to the same address. Do not use quotes in your message.
