1433 intrusion is an sql overflow intrusion. As long as sql2000 is not installed (it doesn't matter if sql2005 is installed), even if there is no firewall, 1433 intrusion will not succeed.

135 intrusion protection is also very simple, just set a login password for the system.

However, the above two intrusions are blocked by your firewall, so don't worry at all. These two attacks are the simplest.

Network attacks can only be prevented. No matter what firewall you change, these attacks will continue.
