NBN Compliant Network Configuration

NBN Compliant Network Configuration

Estimated reading time: 3 min

NBN Australia

The National Broadband Network (NBN) is currently being rolled-out in many locations and replaces the traditional copper-based communications network with fibre-optic cable. The removal of copper phone lines will not only change the way telephones are connected, but will have some implications for practices using ADSL internet connections and associated hardware.

Use this article to help you prepare for the NBN change-over and ensure that your new NBN devices are correctly configured to work with your RxWorks Network. This information may be useful to any practice planning to migrate to the NBN.

However, this mostly applies to practices meeting the following criteria:

  • Your NBN connection will use FTTP.
  • RxWorks has supplied your server hardware.
  • A basic ADSL modem-router is used to connect to the internet.
  • Or

  • You have a Draytek modem router currently configured for non-NBN internet connection.
  • Typical time to delivery from NBN application/notification is 6 weeks. It is important to ensure that any peripheral telephone services are organised for the changeover as soon as possible (e.g. EFTPOS lines, Fax relays).

    Fibre To The Premises (FTTP)

    The NBN may be connected to your practice using one of a few different types of connection. This article specifically covers an FTTP connection (Fibre To The premises).

    If an FTTP connection is installed:

  • Telstra and/or their network partners will remove the copper internet/phone connections to your building & replace them with a fibre-optic connection.
  • Telephone and internet connection will be restored using a new modem/router device supplied by your NBN provider.
  • The NBN router will be configured to allow IP Telephony or VOIP (Voice over internet protocol).
  • Implications For Your RxWorks Network

    RxWorks Servers require a standardised business network that does not typically include telephone connections. The focus of the NBN is on providing an IP Telephony-friendly network & fast internet access, rather than integrated business networks.
    NBN routers intended to optimise voice communications can be detrimental to your internal practice network performance if there is too much interaction between the two networks.
    To prevent any conflict between the two systems, RxWorks requires the network to be reconfigured as outlined in the remainder of this article. The design of this network allows the standard business network to operate effectively under the NBN network layer.

    You may be required to replace your existing modem/router device with one supplied and tested by RxWorks. Alternatively, a reconfiguration of the device will be required if you already have a VPN capable router.

    Technical Information

    Basic Network Diagram

    The schematic below represents the recommended device connection chain.

    RxWorks can supply a VPN-compliant Router to be integrated into the network. Our support technicians will liaise with you & the NBN Provider to ensure the network devices are configured correctly.

  • Your NBN technician must reserve an IP address on the NBN LAN.
  • RxWorks will assign the reserved IP to the RxWorks router WAN port.
  • RxWorks will pre-configure the supplied router according to the information provided your NBN provider.
  • The RxWorks router will be responsible for the practice wireless network (WLAN).
  • RDP Port Forwarding

    RxWorks requires specific Port Forwarding for remote support access. Your NBN technician will need to forward the following ports to the RxWorks router from the NBN router:

  • TCP 3389
  • TCP 3390
  • TCP 3589
  • TCP 3689
  • Ports need to be forwarded from ANY EXTERNAL SOURCE Ip. IP filtering will be configured in the RxWorks router to maintain security.

    VPN Pass Through For Branch Practices

    If you have a multi-branch practice, each branch is likely to be connected via a VPN. Users who work remotely are also likely to use a VPN connection to the main practice. To ensure that the VPN connection remains functional, you will need to provide some information to your NBN provider.

    Your NBN technician will need to open & forward (bidirectional) the following ports to the RxWorks Router from the NBN router:

    For PPTP:

    IP Protocol = TCP, TCP Port number = 1723 (Used by PPTP control path)
    IP Protocol = GRE (value 47) (Used by PPTP data path)

    For L2TP:

    IP Protocol Type = UDP, UDP Port Number = 500 (Used by IKEv1 – IPSec control path)
    IP Protocol Type = UDP, UDP Port Number = 4500 (Used by IKEv1 (IPSec control path)
    IP Protocol Type = ESP (value 50) (Used by IPSec data path)

    For SSTP:

    IP Protocol = TCP, TCP Port number = 443 (Used by SSTP control and data path)

    For IKEv2:

    IP Protocol Type = UDP, UDP Port Number = 500 (Used by IKEv2 – IPSec control path)
    IP Protocol Type = UDP, UDP Port Number = 4500 (Used by IKEv2 – IPSec control path)
    IP Protocol Type = ESP (value 50) (Used by IPSec data path)

    A Guide To NBN Devices

    NBN Modem/Router

    Your NBN Provider will supply you a new Modem/Router that is required to run the IP Telephony system. This device controls telephone connections & also acts as an internet gateway.

  • Your provider may not give you a choice of what device you receive.
  • The provider will choose the appropriate device for you, based on your service contract & business needs.
  • IP Phones

    Your new IP Phones will communicate directly with the new NBN Router. The phones will use the internet connection to establish phone calls.

    There are a variety of NBN compatible phones to choose from, including corded & cordless devices. You will need to discuss your specific phone requirements with your provider.
