Add dynamic IPv4 addresses to Single Layer 2 Firewall interfaces

You can add one dynamic IPv4 address to each physical or VLAN interface on a Single Layer 2 Firewall.

1. In the navigation pane on the left, select Interfaces.
2. Right-click a Physical Interface or a VLAN Interface and select New > IPv4 Address.
3. Select Dynamic.
4. From the Dynamic Index drop-down list, select a DHCP index.
   The index is used for identification in other parts of the configuration (such as IPS Policies) to represent the possibly changing IP address.
5. If the interface is used for system communications and NAT is applied, add contact addresses.
   1. Enter the default contact address in one of the following ways:
      • In the Default field, enter the contact address.
      • Select Dynamic and define the translated IP address of this component.
   2. If components from some locations must use a different IP address for contact, click Exceptions and define the location-specific addresses.
6. Click OK.
   The physical interface is added to the interface list.
7. Click Save.
   If you plan to add more IP addresses or change the roles that interfaces have in system communications, do not close the Engine Editor.

   Tip: Write down the networks to which each Interface ID is connected.
