In this example: We need to allow 1 or 2 computers to bitdefender.net and keep off all the other computers to access this site.
In order to create the rule, we will use negation in the object that will drive the source IP addresses.
It is a deny rule that will focus on two objects:
The first object “Source IP address” will be linked with the switch “Is Not” and we fill this objetct with the ip address of our 2 computers allowed to bitdefender.
The second object “Web server or domain” is focused to “bitdefender.net" domain
