Creating objects

This step consists of creating the objects that will be needed in the configuration:

• Host objects corresponding to operator gateways (if these objects do not already exist),
• Host objects corresponding to VoIP servers (if these objects do not already exist),
• A router object that uses operator gateways and makes it possible to set constraints relating to VoIP traffic.
  This is the router object that will be used in filter rules for VoIP traffic.

In this technical note, we will assume that three interfaces on the firewall are linked to three operator routers:

• One interface is connected to the first operator’s first router (Router1).
  In this example, the IP address of this interface is 10.0.11.1/24.
• One interface is connected to the first operator’s second router (Router2).
  In this example, the IP address of this interface is 10.0.12.1/24.
• One interface is connected to the second operator’s router (Router3).
  In this example, the IP address of this interface is 10.0.13.1/24.
