I don't have an option called "IP Whilelisting," I only have "Domain" > "Settings" > "IP Access." I tried adding there but all I did was block traffic from all other IP's while only allowing those. As I later noticed in the manual:
"You can define IP access rules to allow/deny users' access based on IP address for this domain.
If you do not specify an IP address, all the domain users can logon the server with any IP address. But if
you set an allow list, the domain users can only obtain access by IP addresses specified in the list."
Nothing under "Domain" > "Settings" > "General" either. Is this a version limitation? We're on 5.0.6. I could have sworn we'd done this on an older version though. Perhaps via the console (lua)?
