In pfSense, is there a way to have a rule affect only those people in a certain range of IP addresses (as in, a range that you can't use a subnet mask to match)?
For example, a typical setup of ours is to have an internal subnet of say, 192.168.99.0/24. The DHCP Range that we usually use (DHCP server isn't running on pfSense) is 192.168.99.100 thru 192.168.99.199. What I would like to do is block outbound SMTP on only the machines that have a dynamically assigned address. Is it possible to create a single rule in pfSense to accomplish this?
