Hi,
I've deployed 2 x RUT955s. We've a Private IP Address SIM, local signal quality is good.
1 Device connected to LAN port. This (Windows PC based) device does not usually "dial-out" to the internet, but does listen to external TCP connections.
The relevant port is forwarded on the RUT955. I also port forwarded the RDP ports so we've some access to the PC.
Remote UI Access is also enabled to the RUT955, but not the remove management service (It wasn't clear if this carries a charge)
Firmware will be fairly recent, updated in the last 4 months.
I've had engineers on site, they could hook their laptop to LAN2 and operate the system.
We've had a lot of problems with the connection dropping. I did notice that "Mobile on Demand" was ON, this is now switched OFF.
The engineers moved to another site, I could still remote into the system via the VPN provided by the SIM Card.
They checked the 2nd site, I could also remote into the 2nd system, no obvious problems.
But, it's been reported that the connection is down. I've just checked remotely and both systems cannot be reached.
A windows PING gives;

I do have a backup of one of the systems (.gz), but the first file appears corrupt. This is proving very difficult to fault find due to the system being 6hrs+ drive away. I've not had a problem like this before, we previously used the RUT955 with no issues, but obviously different firmware.
I've found the SIM Config in the backup, does anything here look suspisious?
We've a single SIM Card (in SIM 1 slot), SIM 2 should be disabled.
