To start with the IP Plan, you have to enter your Subnets. Press Create Subnet in the Module IP Plan - Subnet.
After you have entered the Subnet, you will see an overview of used IP addresses in the subnet.
Here you can enter DHCP Scopes. This information will be used in the IP Plan only for visualization. You can also exclude ranges.
Here you can document your Firewall.
The information from the Firewall will be used in the Module IP Scan and in the IP Plan.
Here you can document your (public) DNS infrastructure. e.g. external Servers. This information is required for Certificate checks in case you are using the Module IP Scan. Also, the DNS Information will be used for the IP Plan.
When creating subnets you have the possibility to add Configuration variables which can be referenced in some Job actions.
To use the configuration variables, the following syntax must be used: $[Configuration name]
NAT describes the translation of network addresses behind and in front of the firewall, which is why the input and output IP address is specified here, as well as the port over which the connection runs.
