Many companies prefer to keep their data and software running on servers that are in their own offices, not in the cloud. That means your staff need a way to easily and securely connect to the office when they're out and about.
Virtual Private Networks have been the standard way to do this for close to two decades. Essentially, using some smart software, it's possible to create an encrypted connection across the Internet. That requires some software on the client systems and a router that allows your internal network to securely connect to the outside world.
D-Link has introduced their new DWR-925 4G/LTE VPN Router. This device allows users to create a private network from the home or office with a simple setup and advanced configuration options that guarantee security and easy access to mobile broadband networks.
Given that your business needs to stay constantly connected, it has the capacity for you to connect two Internet services to the router. One can be your primary cable, ADSL or NBN connection with the other coming from the 4G/LTE modem that's built into the device - all you need is a SIM card from your preferred carrier. That way, if the main connection fails, the DWR-925 can automatically failover to the secondary connection.
VPN support covers all the main bases with IPSec, L2TP, and PPTP connections supported. There are four Ethernet ports so you can connect wired devices within your network although these are limited to 10/100 connections and not the more recent Gigabit standard. Wireless connectivity is covered by 802.11 b/g/n. It lacks support for the more recent, and backwards compatible, 80211ac standard.
