2.1 Configuring the Local Firewall

2 SIP


2.1 Configuring the Local Firewall

Before You Start

You must have a Network Interface created.

Steps

  1. Go to Network/Local Firewall.
  2. In the Local Firewall Rules table, complete the fields as required.
  3. In the Local Firewall Configuration table, from the Default Policy selection list, select Drop.

    Important

    Before setting the Default Policy to Drop, i.e. to apply the local firewall rules and to drop any incoming call that does not match a rule, review your rules to make sure that at least one rule accepts incoming packets for management, otherwise the communication with the Mediatrix Sentinel will be lost.

    Note

    For example, if the Web interface is used for management (HTTP port 80) via the unit's LAN interface (default IP address = 192.168.0.10), then the following rule could be added:Activation=Enable / Destination Address=192.168.0.10 / Destination port=80 / Protocol=TCP / Action=Accept

    Note

    For blacklisting to be used, at least one firewall rule must have the Black listing enable box checked.

    Note

    Before setting the Default Policy to Drop, review your rules to make sure that at least one rule accepts incoming packets, otherwise the communication with the Mediatrix Sentinel will be lost.

  4. Click Save.

    Caution

    Take the time to carefully review your rules before continuing to the next step.

  5. Click Save and Apply to apply all changes to the configuration.
  6. Click restart required services, located at the top of the page.

Result

The Local Firewall will drop packets without any notification message.

If a rule with the Black listing enable box checked matches a packet and no Rate Limit Value was set, then the source address of the packet will be black listed and all packets coming from this address will be blocked for the duration of the Blacklist Timeout.

If a rule with the Black listing enable box checked matches a packet and the Rate Limit Value has been reached, then the source address of the packet will be black listed and all packets coming from this address will be blocked for the duration set for the Blacklist Rate Limit Timeout.

    Important

    The Mediatrix unit does not support a mix of both TLS and non-TLS links. Once TLS is enabled, it is enabled for all configured gateways.

  3. Click Apply.

4 Disabling Partial Reset - ResetButtonManagement

Steps

  1. Open CLI (Command Line Interface).
  2. Set ResetButtonManagement to DisablePartialReset.

Result

The Mediatrix unit will no longer partially reset the unit.

5 Requirements

CLI

Make sure the Telnet access is disabled. You can look at the Cli.EnableTelnet variable to verify if Telnet connections are allowed. The access is disabled by default.

Additional considerations

  • In the initial configuration of the unit, review the users and change their passwords and access rights according to your security policy.
  • On FXS devices, the Vocal Unit Information allows a caller on an FXS port to dial codes to get information on the unit like the IP addresses and the MAC address. It is recommended to turn this feature off to prevent attackers from gaining information on the Mediatrix unit setup.

7 Documentation

Mediatrix units are supplied with an exhaustive set of documentation.

Mediatrix user documentation is available on the Documentation Portal .

Several types of documents were created to clearly present the information you are looking for. Our documentation includes:

  • Release notes: Generated at each GA release, this document includes the known and solved issues of the software. It also outlines the changes and the new features the release includes.
  • Configuration notes: These documents are created to facilitate the configuration of a specific use case. They address a configuration aspect we consider that most users will need to perform. However, in some cases, a configuration note is created after receiving a question from a customer. They provide standard step-by-step procedures detailing the values of the parameters to use. They provide a means of validation and present some conceptual information. The configuration notes are specifically created to guide the user through an aspect of the configuration.
  • Technical bulletins: These documents are created to facilitate the configuration of a specific technical action, such as performing a firmware upgrade.
  • Hardware installation guide: They provide the detailed procedure on how to safely and adequately install the unit. It provides information on card installation, cable connections, and how to access for the first time the Management interface.
  • User guide: The user guide explains how to customise to your needs the configuration of the unit. Although this document is task oriented, it provides conceptual information to help the user understand the purpose and impact of each task. The User Guide will provide information such as where and how TR-069 can be configured in the Management Interface, how to set firewalls, or how to use the CLI to configure parameters that are not available in the Management Interface.
  • Reference guide: This exhaustive document has been created for advanced users. It includes a description of all the parameters used by all the services of the Mediatrix units. You will find, for example, scripts to configure a specific parameter, notification messages sent by a service, or an action description used to create Rulesets. This document includes reference information such as a dictionary, and it does not include any step-by-step procedures.
