Is there any way to allow access to a URL that resolves to multiple addresses?
Example: http://server.domain.com would resolve to 192.168.1.1 or 172.30.1.1 or 10.1.1.1, 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.
