In your external router you'd block any ICMP traffic going back and
forth, as well as any packets bearing one of your internal IP addresses,
as a source address, especially if these are going INTO your protected
network. Also, kill telnets, fingers, snmp and snmp trap. Actually, kill
any ports that your users will not be using, andl leave just mail, web,
ftp, etc.
