Hello, I'm running win 2000 server edition on one of my ftp servers. A hacker was trying to access my network. I had my McAffee virus scan block all incoming ftp ports until i resolve this issue. My question is, what can i use to block just one IP address? The system log told me that a user at ip XXX.XXX.XXX.XXX failed to login as admin, administrator...etc etc. So, that is telling me someone is trying to gain access. I looked up the ip address on one of those sites and it maps over to China. Anyway, how can i block just specific ips. My virus scanner wont block specific ones, just the entire port.
