First, let me add to Ryan, you can use fail2ban. I love this program!
It cuts a lot of garbage out.
Now that said, you need to expand your concept of network. Start by
sorting your ip addresses. Now do a 'whois' of one. See how many that
netblock hits. Block that netblock. Also do the same for your IP
addresses that you connect from, and allow them. For example, I use
AT&T dsl at home. It is in the netblock 22.214.171.124/12, and if I allow
only that I can still always connect. This may help...
With that approach, you can knock your 300 down to probably 10 or less.
Or allow only the subnet you are likely to use, which would probably
be 5 or less.
