Linked Capacity Plus Example Router Configurations

***Update 01.05.18***

There's been a few spam comments on this post and some commentators were advertising companies involved in technical support fraud. For this reason, I've removed certain keywords so future spammers (hopefully) wont be able to find my blog (and this page) so easy. If not, I'll keep on deleting their comments.

Point Number 1

Do not use a consumer grade router for any 
radio system. All too often I've seen folk spend thousands on Motorola repeaters only to be let down by a €300 cost-cutting measure on networking gear.

Please refer to the latest MOTOTRBO system planner for a list of routers which support Multisite Capacity Plus. The only reason why I used a consumer device here, was to illustrate what was needed to be set up and because I didn't want to go into networking too much during my training.

Point Number 2

As of software release 2.2.0, NAT Loopback is no longer needed in a Multisite Capacity Plus, except when a NAI based application (e.g. Dispatcher) and the Master repeater are on the same LAN.

All Sites

Port forwarding must be enabled.

You can use DHCP for the Peers on the repeater site.

During testing, you can enable the function which allows the Router to respond to pings on the WAN port. Once you're done with this, turn it off.

Site 1

Port forwarding must be enabled. The UDP port used  by the Master is 50000. You will see that I have specified that TCP and UDP should be forwarded - this is becuase TCP is used by the CPS for remote IP programming. 192.168.0.2 is the IP address of the Master.

You can use DHCP for the Peers on the repeater site - though lately I've used static IP addresses all round since radio stuff will typically (or at least must) be on its own LAN. You will see that, in this case, the DHCP issued addresses start at 192.168.0.3 - this is because 192.168.0.2 is reserved for the Master. DHCP also stops at 192.168.0.200, again because 192.168.0.201 is reserved for the rest Channel IP Address.

I also use QoS to give UDP (MOTOTRBO) traffic the highest priority. I also enable the function which allows the Router to respond to pings on the WAN port. If you are connecting via the Internet, disable this feature once you're done with tests etc.

All other sites

On the other site(s), everything is the same, except the port number for the Peers are different  and the Router’s WAN IP addresses are different (see above).

If you have a Nϵtgϵαr Router like this, you can (restore) load this configuration to try out.
