Mobile internet modem with Eternet port

Hi,

Does anyone know of a simple straightforward 3G/4G modem for internet with an etnernet connection.

The world is full of USB modems for mobile internet. There are also lots of modem/routers available.

I am setting up a VPN where I am forced to use a particular IPSec VPN router. Some sites are on mobile 4G Internet though with 4G modem/routers.

I have experimented with some modem routers, but none seem to work with IPSec passthrough to my VPN router.

One of my modem/routers alow bridging to one LAN port but that does not work either. The IP adress gets bridged but standard gateway does not. That is the standard gateway still points to the modem /Routers gateway adress and not to the gateway of the ISP.

So my questio is: Is there a simple straightforward 3G/4G modem out there. I am based in Sweden and I have not been able to find one on the local market.

If such an animal does not exist, I can see that I can disable NAT on one of my Modem routers and maybe make a static route between my modem/router and my VPN router. This route woulld route everything frpm the mobile network to the VPN router, but I am not sure how such a static route would look.

I am getting desperate. Most gratful if anyone can shed some light on the issue.

I am sorry for going silent on this issue for a long period of time.

This project was going out of hand and I had to refocus on finding an alternate solution. In the end we set up a MS software VPN Between the client computers and the WIndows 2008 server. It had been tried before with no success, but after we realized that nuch of the communication originated in the server, I understood that the main issue was that the communication link was initiated from the clients while the modem disconnected the connection after a certain time of inactivity. Any traffic received from the server after that point was lost.

I replaced mobile modem/routers at the client site with the ZyXEL LTE3301 3G/4G Router. This one has a good keepallive and automatic reconnect functionality and was able to maintain a continous connection.

THe client sites are located "out in the wilderness" So mobile coverage is not optimum, but it is good enough to provide a reasonable quality of service.

Thank you all for your efforts
