RW well described (in freebsd-questions@) the relationship between port numbers and service names in /etc/services; assuming you know the name, that gives you the number. Are 'test1' and 'test2' real examples, or placeholders for real service names? In any case, you cannot specify a port number in a rule with proto 'ip'; when specifying port/s you need to specify 'udp' or 'tcp' protocol. Can you give an example of the actual packets (protocol, port number/s) that you want to block? cheers, Ian _______________________________________________ freebsd-ipfw@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ipfw To unsubscribe, send any mail to "freebsd-ipfw-unsubscr...@freebsd.org"
