Hello!
I would also like to know if it is possible to only allow IP adresses on the firewall. If I lookup the IP for aruba.brightcloud.com I get this:
Non-authoritative answer:
Name: bcap15.brightcloud.com
Addresses: 52.210.152.183
52.18.42.238
Aliases: aruba.brightcloud.com
If I open 443 ports to destination 52.210.152.183/52.18.42.238 would that be enough?
Are these IPs going to change in the future?

Daniel
