DCS prevention policy question

Hi All,

Since I work remote, I establish a VPN connection to our Datacenter and then RDP into agent instances. Before turning prevention on, RDP worked fine but since turning prevention on I cant RDP into the instances in our DC. I have enabled via policy a group of addreses via the "Inbound Address List" option under "Global Network Access" but I still cant access the instances. I know I can uncheck the "Globally set the default inbound rules to deny" under Global Policy options but that basically opens up the network. Is there something that I am missing?

Thanks!
