Allowed FQDN that resolve to CNAME records
-
With all of the cloud based services going on, I have a website I want to put in the allowed servers area of captive portal. But if the dns server resolves to a CNAME in the amazon cloud. The amazon cloud FQDN resolves to the captive portal server. In the end this doesn't allow that server to be allowed.
I haven't found a good list of amazon, akamai, etc edge servers to allow those IPs through. And even then, that is a bigger hole than I wanted to allow.
Any thoughts on a solution.
