5 Configure Device
This section describes device configuration.
5.1 Change Default Management User Login Passwords
To secure access to the device's Web management interface, follow these guidelines:

The device is shipped with a default Security Administrator access-level user
account – username 'Admin' and password 'Admin'. This user has full read-write
access privileges to the device. It is recommended to change the default password to
a hard-to-hack string. The login username and password are configured in the Web
Interface’s Local Users page (Setup menu > Administration tab > Web & CLI folder
> Local Users) using the 'Password' and 'Apply' fields:
Figure 5-1: Changing Password of Default Security Administrator User

The device is shipped with a default Monitor access-level user account - username
and password: 'User' who has read access only and page viewing limitations but can
view certain SIP settings such as proxy server addresses. Therefore, to prevent an
attacker from obtaining sensitive SIP settings that could result in possible call theft
etc., change its default login password to a hard-to-hack string.

5.2 Configure a Network Interface for the Device
You can connect the device to the DMZ network using one of the following methods:
Method A: (Preferred method) A global IP address is provided to the device (without
NAT):
Figure 5-2: Method A
The Enterprise firewall is configured with rules, for example:
Original
Source Destination Ports/Service
<any>
(e.g. ITSP) Global IP Address
(public address) SIP service: 5060 / UDP
RTP service: 6000-8500 / UDP
Method B: A local DMZ IP address behind NAT:
Figure 5-3: Method B
The firewall is configured with rules, for example:
Original Translated
Source Destination Ports/Service Source Destination Ports/Service
<any>
(e.g. ITSP) Global IP Address
(public address) SIP service: 5060 / UDP
RTP service: 6000-8500 /

Name Voice (arbitrary descriptive name, you may change it)
Application Type OAMP + Media + Control (leave as is)
Ethernet Device vlan 1
IP Address If working in Method A: Global-IP-Address (public
address)
If working in Method B: Local-DMZ-IP-Address
Prefix Length Subnet mask in bits, e.g.28 (for 255.255.255.240)
Default Gateway The default gateway IP address
(In Method B: router's IP address)
Primary DNS Server IP

5.2.2 Configure NAT
Note:
•NAT configuration is applicable only if you are behind a firewall NAT (see
•Method B).
•The NAT IP Address is the Global-IP-address used in front of the firewall facing the
BroadSoft service. If the DMZ holds the global-IP-address (no NAT is performed by
the firewall) and the Gateway is already assigned the Global-IP-address as its
address, skip this NAT configuration.
Configure the global IP address as follows:
1. Open the NAT Translation table (Setup menu > IP Network tab > Core Entities
folder > NAT Translation).
2. Click New; the following dialog appears:
Figure 5-5: NAT Translation Table - Dialog Box
3. Use the table below as reference when configuring a NAT translation rule.

Parameter Description
Index 0
Source Interface Voice (the interface to apply this rule to)
Target IP Address Global-IP-address. Defines the global (public) IP
address.
Source Start Port (leave empty)
Source End Port (leave empty)
Target Start Port (leave empty)
