HTTP-based Proxy Services

The device supports the following HTTP-based proxy services:

HTTP Reverse Proxy for Managing Equipment behind NAT:
You can configure the device to function as a reverse HTTP proxy server. This
functionality is required to enable administrators to manage communication equipment
(such as IP Phones) over HTTP when the equipment is located behind NAT (e.g., in
the LAN) and the administrator is located in a public domain (e.g., in the WAN). Thus,
this functionality resolves NAT issues, enabling the administrator to access the IP
Phone's management interface (e.g., embedded Web server).
To support the functionality, the following configuration is required:
1. Enable the HTTP Proxy application (see ''Enabling the HTTP Proxy Application''
on page 268).
2. Define a local, listening HTTP interface for the leg interfacing with the
administrator (see ''Configuring HTTP Interfaces'' on page 268).
Note:
Phones for their Web-based management interface.
3. Define each HTTP-based managed equipment:
a.
b.
Note:
equipment.

HTTP-based EMS Services for AudioCodes Equipment behind NAT:
You can configure the device to act as an HTTP Proxy that enables AudioCodes EMS
to manage AudioCodes equipment (such as IP Phones) over HTTP when the
equipment is located behind NAT (e.g., in the LAN) and EMS is located in a public
domain (e.g., in the WAN). Thus, the feature resolves NAT traversal issues. The IP
Phones register with the device in order to allow communication between the IP
Phones and the EMS.
To support the functionality, the following configuration is required:
1. Enable the HTTP Proxy application (see ''Enabling the HTTP Proxy Application''
on page 268).
2. Configure two local, listening HTTP interfaces - one for the EMS and one for the
IP Phones (see ''Configuring HTTP Interfaces'' on page 268).
3. Configure the address of the EMS server (see ''Configuring an HTTP-based EMS
Service'' on page 273).
Version 7.2
It is recommended not to use port 80 as this is the default port used by IP
Define the URL prefix for accessing the equipment's management interface
(see ''Configuring HTTP Proxy Services'' on page 270). To access the
equipment's management interface, the administrator needs to enter the
following URL in a Web browser:
http://<device's WAN IP address:port>/url prefix/
Define the IP address of the managed equipment (see ''Configuring HTTP
Proxy Hosts'' on page 271).
For this feature, no special configuration is required on the managed
