It might, it depends on the quality of link between them, distance etc. Auto VPN isn't magic, just a simple way to connect sites.  With voice jitter is all important so reducing hops and concentrating on link quality is very important. ... View more

We use SIP with two providers, with one we use edge devices that terminate the SIP trunks and the phones and PBX talk to that, with the other it terminates on the PBX but this actually means that once the call is set up the phones talk directly to the trunk.   Is the SIP gateway on the internet, if so and it terminates on the PBX I'd set it up for a ll sites to talk to it directly to minimise jitter when in a call, they'll talk to the PBX at the HQ for call setup (signalling) and then hand off.   Are you creating an SD-WAN to link the sites? ...

I think you are confusing WAN and DIA (internet), WAN is generally used for connections between sites, either directly cabled or using provider technology like MPLS, VPLS or SD-WAN.   If I've understood correctly, then the router at site A must be a firewall of some sort.  You could use bridged mode and then if the MPLS devices are set up correctly, the sites will talk and you will have a degree of traffic visibility.  Otherwise put them in routed mode and configure the WAN ports with your settings and pick a subnet for the LAN at each site.  ...

If by WAN you mean internet connection then your s ettings look fine on site A for that purpose, for site B, as long as the MPLS device sends traffic to the other one at site A if it is unknown then that is okay as well.   If by WAN you mean the MPLS tails then where is the internet connection?   The MXs at each site will need to be in separate networks in the same organisation.  If you want the two LANs to talk to each other then create an auto VPN (SD-WAN) and the two LAN subnets will be able to see each other.  ...

At site A do you have both WANs plugged into the one device?  Do you have two WAN links for one MPLS or two internet connections and one MPLS WAN, or one MPLS with internet access from the core and a second internet connection locally?   Why are you hoping the MXs can do, besides NAT the LANs to the MPLS? ...

@IotaNetworksyou have two issues here.  Firstly I'd hazard a guess that the LAN port of the MX you are trying to add is in the 192.168.24.0/24 subnet, if not then you can proceed, although it will affect the ability of that MX to talk to the 192.168.24.0 network.  The second issue is that, unless you don't need to talk to the outside world, the 192.168.0.0/12 network covers the IP ranges 192.160.0.1 - 192.175.255.254, most of which are genuine public IPs and not private ones, you will not be able to access any of them so I'd fix that first! ...

@hockeydude you are correct that one flow will only use one link but if you have more than one flow going on then both links should be active.  This should be the case in most circumstances. ... View more
