Hi. if your running linux try something like iptables -t filter -A INPUT -p tcp -s 0.0.0.0 --syn -j REJECT --reject-with tcp-reset
this way you get ALL the ports closed, even the local range ports and still have a working connection, then open the ones you need to have open. The --syn flag drops all packets that have syn bit enabled and ack bit not(these are the connection initiation packets).
