Preventing Brute Force Attacks!!!!!

$

Is it possible to ban an IP addresses after X number of unsuccessful login attempts to a Windows XP Sp2 which is our SFTP server? Not to a particular account, which I know how to do, but to the whole machine. Or how to block ICMP request on external IP which use NAT to our internal network.

We get hit pretty hard by brute force attacks trying to guess usernames and passwords, so this would really help get some load of the server. Does anyone know how to block these attacks? btw we have Astaro security gateway 320 V7. We have blocked the ICMP off the server but need to find a way to block those false IP addresses attempting to connect with different users and passwords. Please advice/help will be appreciate!!

Thank you,
