We have a Balance 580.
Is there any way to block inbound traffic by domain name?
This is an extremely desired and required capability. Blocking inbound only by IP range is extremely cumbersome, especially since there is no way to import or batch edit blocked IP ranges. We get a huge amount of SPAM even with a well-configured Barracuda and would like to block certain domains and geographic regions (countries). For example, we do not wish to receive ANY traffic from .ru or .co. This would be so much simpler than manually and individually inputting 100’s of IP range blocks.
Because we have multiple WAN inputs, if we cannot do it with the Balance 580, we would have to put an additional firewall on every incoming WAN and redundantly configure each one - extremely inefficient.
You have outgoing domain blocks - why not incoming also?
