Is there any way to allow access to a URL that resolves to multiple addresses?
Example: would resolve to or or, depending on when DNS requested it.

We have a program that requires access to an off-site URL that resolves dynamically to at least four (so far) IP addresses - none in the same class A range.

I've added it in the Access Rules in NWAdmin, but it didn't help. So far, I've been adding filter rules as new addresses come up.

Thanks for your help.
