MX68 - LAN Port - Telstra Nightawk

[SCC]

Hi Team,

I have a Scenario for MX68. I would like to use the Internet1 for one NBN link and Intenet 2 for second NBN link and I want to use Telstra Nightawk on the LAN Port just for the VOIP Traffic.

As Telstra Nightawk has the RJ-45 Port, if i plug this to MX68 LAN port can i route my VOIP traffic to just go via the Telstra Nightawk LAN port.

Hi SCC,

There is probably a few ways to do this.

As the Nighthawk is essentially a router you could setup a separate VLAN just for your phone(s) to communicate to it as their default gateway rather than the MX68.

As as far as MX is smart enough that it can identify my VOIP Network which is (10.227.8.0/24) and can route it via the Telstra Nightawk Interface. It should be fine.

You would need to define all the possible IP destinations, used by your phones, as static routes, pointing at your Nighthawk interface. MX does not currently support source based routing, which is what I think you're looking for. If you don't want to add the routes - or don't know all possible destinations - then Benny's is a good alternative

what if i connect this Telstra 4G on the Internet2 (WAN) port. Can i use this Telstra as a failover or just for a dedicated VOIP traffic.

You could use an uplink Flow preference to push your VoIP traffic to Internet/WAN 2 as an SD-WAN rule.   Look under Security & SD-WAN > Configure > SD-WAN & traffic shaping   Under Flow preferences, Internet traffic (assuming this traffic isn't to be VPN tunnelled?)

You would need to be able to define the necessary traffic using these variables:

Protocol; Source IP; Src port; Destination IP; Dst port.   (you can sub Any for specifics, within these)

This traffic would fail over to WAN 1, if WAN2 failed.

We tried the Telstra nighthawk but had issues where it would fall asleep and disconnect WAN2.
