4G embedded router

I have a device with an Ethernet connection that the user usually  
connects to ADSL router.

I'd like to offert a 4G connectivity too. I could replace the Ethernet  
adapter board with a 4G adapter board, but the effort is too high for us.

So I'm thinking to use a 4G router, that is similar to ADSL router, but  
has a 4G modem instead of ADSL model. There are many products available  
on the market.

However I'd like to embed a 4G router in my product for many reasons:  
better customer impression and the possibility to supply the router when  
the mains is absent (my product has an internal battery as a secondary  
power source).

So I'm searching for a small embeddable board that features a SIM  
holder, a 4G modem and 1 or 2 Ethernet ports. I will connect my Ethernet  
board to this 4G router.
Do you know of something similar?

How difficult is to design this?

Be glad if you find one which will allow you to do PPP... Good luck.

No, I'm searching a board with a "full" router OS that features a DHCP  
server (so my Ethernet board receive automagically an IP address) and  
will route all incoming packets from 4G connection to the Ethernet port  
and viceversa.

The router OS should try to keep the 4G connection active all the time  
with the mobile operator.

The goal is to avoid changing the firmware on my Ethernet board.

You mean you want a '4G router', for instance:
(add your own USB 4G stick)

or are you constrained by needing a bare board (standard mount points, etc)?
Then things like:
if you're feeling brave.

Check out

Not a board, but a box which looks promising.

Yes, it could be good. Unfortunately the power supply seems only 5Vdc

Thanks for suggestions, but I was searching something much smaller.

I've used Teltonika routers in many projects, they've also got them as boards:
