5.1 Step 1: Configure IP Addresses
5.1.1 LAN and WAN Interface Separation
This section describes how to configure IP addresses when the internal data-routing
capabilities of the MSBG device are used to connect to the PAETEC SIP Trunk. In this
case, configure a separate WAN interface, as shown in the figure below.
Notes:
• The VoIP and Management interface must be in the same subnet as
the data-routing interface, as shown in the figure below.
• When operating with both VoIP and data-routing functionalities, it’s
recommended to define the Default Gateway IP address for the VoIP
network interface in the same subnet and with the same VLAN ID as
the IP address for the data-routing LAN interface, as shown in the
figure below.
