The Interfaces wizard page configures the device's LAN and WAN settings.
Figure 53-4: SBC Configuration Wizard - Interfaces Page
To configure LAN and WAN interface settings:
1. From the 'Physical Port' drop-down list, select the Ethernet Group containing the
required physical Ethernet port for connecting the device to the 1) Enterprise LAN
(typically, a switch) or 2) DMZ port of the Enterprise router for WAN. You may
configure two physical ports for Ethernet link redundancy.
2. Select the VLAN Tagging check box, and then in the 'VLAN ID' field, configure the
VLAN ID for the interface. For untagged traffic, clear the check box.
3. In the 'IP Address' field, configure the device's IP address on the interface.
• For LAN interfaces: The IP address must be part of the Enterprise LAN and
therefore, is typically a private IP address. The address is used for
communicating with the IP PBX and/or users that reside on the LAN, as well as
for management (OAMP) traffic.
• For WAN interfaces: The IP address must be a public (globally routable) address
and is used for communicating with the ITSP and/or IP PBX that resides on the
WAN. If the WAN is the only interface, it is also used for management (OAMP)
traffic.
4. In the 'Subnet Mask' field, configure the subnet mask of the interface.
5. In the 'Default Gateway' field, configure the default gateway of the interface.
6. If the device is connected through an Enterprise router that performs NAT, then in the
