hi all
i have here an windows SBS 2008 with a monowall behind. here i have configured nat - rules, the standard ports forwarded to server ( ports:25,80,443,987,1723,3389). Today i see that i have many audit failures in logs, so many from outside try to login over my server, so how can i say nothing from outside can come in, only servers or users they are want over the open ports. is that one rule, or how i must make my firewall to a really firewall, i want block everything who wants to come from outside to my server only the open ports. i dont understand it, how to make here the right rule! have someone help for me?
