Annoying situation. We have a vendor who's cloud endpoint reaches into our on premises server (their software) via a public IP:Port with all connections blocked except their IPs. They recently changed cloud configuration and now want us to use a DNS record for this allow. As far as I can tell I can only use IPs in the "Allowed Remote IPs" section of the NAT port forwarding rules. I figured I'd just look up the records for that host name, and allow those. Even just a day later their servers have changed a few IP addresses. Is there any way to allow only that specific DNS domain to that port? If I do put the FQDN into that box, the settings will save without error, but the list is not used.
