default configuration.
Some of the PBX/Gateway devices may have an exclusive LAN/Mgmt Interface for
device management purpose other than the Data Interface (also referred as the
WAN/Public Interface). In such cases LAN port of the SIP Firewall should be connected
to the Data Interface (WAN/Public Interface).

The device operates as a transparent bridging firewall with Deep Packet Inspection
enabled on the SIP traffic. By default, the appliance has been configured with static IP of
10.0.0.1 (Net mask 255.255.255.0).
The device has been made to be fully functional with the default configuration. However
if the user needs to tune the device settings & the DPI policies, they can tune the
configuration via the Device WebUI.
The device also provides the command line interface accessible via SSH, which will
allow configuring the basic settings and viewing device status.

Management Vlan IP

Default Device IP

Accessing the WebUI
The user can connect to the device via management Vlan to access WebUI during initial
setup. The management Vlan configured on the device, is accessible via the LAN/WAN
ports & is made assigned to the default IP address ‘192.168.100.1’
Use the procedure given below to access the WebUI,
1. Connect the LAN port of the SIP Firewall to a PC.
2. Assign the IP Address 192.168.100.2 to the PC. Set the Net mask as
255.255.255.0.
Now you can access the device from the browser using the URL https://<192.168.100.1>
Configure the SIP Firewall Device IP Address from the “Device Settings” Page as per
your local network range. Verify the IP address set to SIP Firewall from the dashboard
page. Once the user assigns the SIP Firewall Device IP Address successfully, he can
access the device using that IP address further.
Now he can disconnect the PC and connect the LAN Port to the PBX/PBX Network that
needs to be protected.
The WebUI has been made accessible only via HTTPS. The recommended
browser for accessing SIP Firewall WebUI is Mozilla Firefox.

The UI allows the administrator to configure the management Vlan IP addresses.
In case if the user has changed the management Vlan IP address, they need to assign
the corresponding network address to his PC for the management access subsequently.
Alternatively the user can access the device via the static IP 10.0.0.1 and
configure the network settings during first time installation. Connect a PC to the LAN port
of the STM and assign the IP address 10.0.0.100/255.255.255.0 to the PC. Now you can
access the device from the browser using the URL https ://< 10.0.0.1>
If the device is not accessible after configuring the new network configuration, Try
rebooting the device and check the device dashboard accessing via Management Vlan.
On launching the SIP Firewall WebUI, the web application will prompt to enter the
administrator credentials to login.
