These have to be entered in CIDR notation (Classless Inter-Domain Routing) (e.g. 81.81.81.2/29).

Info

The first IP address is always used for general communication. If necessary, change the order of the IP addresses via the arrow symbols.

In this example the IP address range 81.81.81.1/29 is used with a total of 8 IP addresses. Of these 5 IP addresses are usable.

81.81.81.0: This is the network address and therefore it cannot be used.
81.81.81.1: In this example this IP address is used by the Gateway (Provider router) and therefore it cannot be used.
81.81.81.2 - 81.81.81.6: These IP addresses aren't reserved otherwise and therefore can be assigned to the Unified Firewall and used freely.
81.81.81.7: This is the Broadcast address and therefore it cannot be used.
