A router that has two wide area network (WAN) ports for connection to different Internet providers. Dual WAN routers are useful in areas with frequent ISP outages, and they can be configured to switch over if the one currently used fails.
Expanding your bandwidth with more than one broadband connection provides load balancing andsecurity to the internet that ensures your business always .
Dual-WAN or multi-WAN routers give you reliable Internet at all times coupled with load balancing and security. They are most essential for those who are likely to get impacted even with short Internet outages and for those who want to combine the bandwidth of two or more providers.
Multi-WAN routers are highly useful for those who need the Internet at all times and when even a few minutes of nonavailability can impact them in a big way. With multi-WAN routers, you don’t have to rely on a single Internet ISP only and this is a big advantage when you live in an area with a patchy Internet connection. These routers allow you to have an Internet connection from two different ISPs, so even if one fails, you still have access to the other.
These routers also help with Internet load balancing so you can enjoy a reliable Internet service at all times. When you use many applications such as web browsers, VPNs, streaming services, and emails, you tend to use high amounts of bandwidth and the entire load is passed to a single ISP in a traditional router setup. But with multi-WAN routers, this load is spread across two or more ISPs, so the overall Internet speed tends to be faster.
Many dual-WAN routers come with L2TP VPN to help employees to securely connect to your network. Also, it allows you to over public networks, thereby reducing the possibility of hacking or unauthorized reading of transmitted content.
