Http-Based Proxy Services - AudioCodes Mediant 4000 SBC User Manual

15.7

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 283).
2. Define a local, listening HTTP interface for the leg interfacing with the
administrator (see ''Configuring HTTP Interfaces'' on page 284).
Note: It is recommended not to use port 80 as this is the default port used by IP
Phones for their Web-based management interface.
3. Define each HTTP-based managed equipment:
a.
b.
Note: For this feature, no special configuration is required on the managed
equipment.

HTTP-based OVOC Services for AudioCodes Equipment behind NAT:
You can configure the device to act as an HTTP Proxy that enables AudioCodes
OVOC to manage AudioCodes equipment (such as IP Phones) over HTTP when the
equipment is located behind NAT (e.g., in the LAN) and OVOC 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 OVOC.
To support the functionality, the following configuration is required:
1. Enable the HTTP Proxy application (see ''Enabling the HTTP Proxy Application''
on page 283).
2. Configure two local, listening HTTP interfaces - one for the OVOC and one for the
IP Phones (see ''Configuring HTTP Interfaces'' on page 284).
3. Configure the address of the OVOC server (see ''Configuring an HTTP-based
OVOC Service'' on page 289).
User's Manual
Define the URL prefix for accessing the equipment's management interface
(see ''Configuring HTTP Proxy Services'' on page 285). 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 287).
