NAT Loopback no longer a requirement for Linked Capacity Plus.

As of firmware release R02.20.02, a router which support NAT loopback is no longer a requirement for Linked Capacity Plus. NAT is still required but is generally supported by all routers.

So what does this mean?

In terms of configuration, the Peer repeaters on the same LAN as the Master only need to be provisioned with the LAN IP Address of the Master repeater (and not the WAN IP Address of the Router as was the case prior to R2.2).

The Peers on the other sites, still need to be provisioned with the Master sites' WAN IP address (i.e. the WAN IP Address of the Router to which the Master is connected). The Master also still needs to be provisioned with the Routers' WAN IP address (see the CPS feild Master IP, under Network, in the Master Repeater codeplug).

  2. Hi Wayne and thank you for your wonderful and helpful blog!
    I was wondering if you could help me out with a question:

    I have some radios that I need to activate the licenses to, and I need to know whether I should upgrade their codeplug / firmware before I do so.

    So the question is:
    What is the oldest firmware / codeplug version that a portable radio must have in order to work in a Linked Capacity Plus environment?

    Thanks!

    1. R01.09.00 for the first generation radios and R02.05.00 for the second generation radios.

  3. Please note that we are in the Latin American region and that the radios are DGP4150 and DGP6150 (XPR series for other regions)

    Thank you!

  4. Hi, I don't understand why all paper spoke about WAN address.If a LAN is available between all site it should be not necessary

    1. A router is still needed as the local channel management on the sites is announced on address 255.255.255.255 - if this traffic were to get from one site's LAN to another, the system would become erratic.

    2. WAN here refers to the medium linking the sites - which could be almost anything.

  5. Mr Holmes,

    Is there any link to understand the call flow and channel allocation in Mototrbo Linked capacity Plus 2 Sites or in 1 site.
