I ended up with 10 of these IBR900-1200M's for customers fleet. S2S VPN connected them to a Cisco ASA, which took a bit of finessing to figure out the ikev2 settings and get them to work right. Also allowed us to secure them to FIPS standards.I don't like the subscription costs of the units, and find it unnecessary price gouging. But, if your willing to pay for it, these worked quite well once configured properly. The Netcloud interface is not very intuitive, and difficult to find what your looking for. But you can get the job done. I wouldn't recommend this unit if not technically savy and needing more than a standard 'plug the sim in and go' configuration. Took me (senior systems engineer) and our senior cisco engineer 8 hours of fiddling to get the tunnels up because of a bug in the cradlepoint interface. If the IPv4 address range has changed for the device, delete the entire tunnel config and start from scratch if you can't get the tunnel to authenticate.Not sure where the antenna came from, it wasn't a mobilemark, i think it is the cradlepoint vehicle antenna for this unit, and it is massive. Entirely too large.With Verizon, near a 4G LTE tower, seeing from 7Mbps to 60Mbps both on the up and down. Varies depending on congestion and weather conditions. So the CAT16 is entirely too much for verizon. A 600mbps unit would be plenty.If the purchase was entirely my call, i would of went with the Peplink Pepwave BR1 MK2 though. Simply because of the requirement of Cradlepoints Netcloud subscription in order to obtain firmware updates for the unit. And its not as cheap as it should be either.
