This is probably a little vague, but I will start here.
I am starting to work on a project to begin next financial year on having some equipment in the field (SCADA devices) connect back to our head office over some form of VPN such as IPSec.
One potential candidate we might look at is Peplink
The field devices do not move physically, however they are spread over a large area and in some harsh conditions (direct sunlight 40c days are normal in summer) and some central monitoring is critical so see whats up / down etc. The devices need to be rated for field use.
We would require close to 1000 field devices such as a Pepwave Max BR1 4G and possibly extend to as far many as 2000 in the longer term future
Unfortunately our existing firewall is rated to only support 1000 max VPN connections and additionally we want any load from maintaining these connections to be on a separate device
Is there a Peplink Balance model suitable? Seems the 2500 model lists 800 maximum IPSec tunnels
Being regionally based in Australia also means the quality of internet connections we have a sub-optimal, we currently make use of several ADSL 2 Connections and a Telstra Fibre connection 10MB/10MB Is there some way to balance incoming tunnels to be spread across multiple connections to reduce any load.
In addition in event of a complete site internet outage we have a secondary branch office which we could also place a device for incoming connections, the two sites are connected via a dedicated 100KM Wireless Radio link, which is very reliable.
Is Peplink a potential use case? does anyone use similar numbers of devices that size? If anyone could provide references or info it would be very handy thanks
We are weighing up going down the managed Telstra Service which comes at great cost, or a potential cost saving to the business by using Peplink/Other vendor.
