How to Create Wildcard Network Objects

  • Last updated on

Wildcard network objects are network objects that include a network mask containing information regarding which parts of the IP address is to be evaluated. Wildcard network objects can be used to describe IP addresses that cannot be covered by network objects using subnets masks.

Examples

Wildcard network objects are entered in the format IP address/network mask:

  • 0.0.0.1/0.0.0.255 = *.*.*.1
  • 0.200.0.0/0.255.0.0 = *.200.*.*

Create a Network Object

  1. Go to CONFIGURATION > Configuration Tree > Box > Assigned Services > Firewall > Forwarding Rules.
  2. In the left menu, click on Networks
  3. Click Lock.
  4. Right-click the table and select New. The Edit/Create Network Object window opens. 
  5. From the Type drop-down list, select Generic Network Object (IP, Network, Range).
  6. Enter a Name.
  7. In the Include Entries section, click + . The Edit/Create Include Entry window opens.  
  8. Enter the IP and network mask for the wildcard network object in the following format: IP/network mask. E..g, 0.0.0.1/0.0.0.255
