We list here some of the best selling Industrial 4G routers for use with Wireless Logic Fixed IP SIM Cards.  These routers provide reliable and secure 4G connectivity and when using a Wireless Logic Fixed IP SIM card the router APN is configured with WLAPN.COM or WLAPN4.COM and the router will then connect to the Wireless Logic APN and the router 4G Internet connection will receive the public IP address.  In many cases the Wireless Logic M2M SIM card will have a public fixed IP address so that the router can be connected to directly from the Internet and can use features such as port forwarding.  In these cases please ensure you correctly configure your router firewall and remote admin features to prevent unauthorised access to your router.  If you have opted for a private fixed IP SIM card then in order to connect to the 4G router once it has connected to the Wireless Logic APN you will need to create a VPN from your PC to the Wireless Logic VPN server and you will then be able to access the router over the VPN service.  You are not connecting directly to the router using the VPN, but are connecting to Wireless Logic so you can access private IP addresses on the Wireless Logic network.
