For some reason the McAfee Web Gateway is requiring IP Addresses to be whitelisted, even tho the Domains are whitelisted.
We've checked the url via https://www.trustedsource.org/en/feedback/url and it returns as minimal risk.
Is there some setting that indicates IP Addresses need Whitelisted?
We'd need a little more information to help identify the problem.
Do you know what rule is causing the block? If so, can you share that portion of your rules with us?
I am not sure I can, as this is a client of mine. But I just noticed there are "Rules" that are IP based (not domain based). I think that is the direction for research. Can you point me to online documentation about the Rules, and how Web Gateway processes thru the 'cycles'.
