Define a group of networks

Question

Hi, 
 
 I wish to create a rule that will permit SMTP traffic from a number of network addresses, as defined below: https://www.spambrella.com/faq/data-center-information/ 
 I can see under Hosts & Services where I can defined a single host as a network however not multiple networks. 
 Do these individual entries need to be defined as individual ip hosts? 
 I was hoping to create a single entry called Spambrella that would contain all of the networks defined above. 
 Is this possible?

Hi McHenry , 
 Thanks for reaching out to the Community! 
 Yes, you'd have to add networks as single host entries and then create an IP host group with those networks. You can then use the IP host group object in firewall rules. 
 If you want to update the configuration offline and then import it to the firewall, you could use the import/export feature; check out the following document for more info:
