DROP all -- 114-43-XXX-XXX.dynamic.hinet.net anywhere DROP all -- 118-161-XXX-XXX.dynamic.hinet.net anywhere
These are just two of the several restrictions I have in IPTables right now because this person is constantly connecting to postfix. Luckily, the server does not allow him to send messages because relay access is denied. I would still like to block this person from accessing my server. Is there a way to block the whole group of IP's using dynamic.hinet.net instead of specifying IP Addresses everytime?
