@evanevery I wish you all the best of luck. If I find anything suitable in the meantime I'll update you.

@David-TP Hi David I'm not sure if you have seen my post in the other thread, but to just let you know that my M8550 is on its way back to my supplier. Many thanks for your time to come back to me,...

@evanevery That didn't go well! I thought that rather than keep removing the sim card out of my company phone to test, I'd initially use the WAN connection, and guess what, the dictionary definition...

@evanevery Surely with remote access if a tunnel is not built, they will not lose the connection? Like I say mine just keeps flashing up "connecting" and no more. I'm shocked at the lack of testing...

@Thirtified Passthrough being any router that can host as a client or server behind it, so nothing special. do a price comparsion and see how it looks I suppose.

I've never played with the Teltonika stuff. I run a Draytek at home, and find it does what it says on the tin. The only issue I have found is trying to log to USB, causes reboots.
