IPv6 Support for IoT Networking
With billions of new IoT devices entering the market each year, IPv4 is faced with the issue of not being able to
fulfill the requirements of connecting all the IoT products together. IPv6 offers a highly-scalable address scheme
that provides a unique 64-bit host ID to every present and future IoT device. It is sufficient to address the needs of
any present and future communication device. That means IPv6 allows IoT products to be uniquely addressable
without having to work around all of the traditional NAT and firewall issues.
The WGR-500 Series supports both IPv6 and IPv4 to ensure industrial Ethernet with a smooth migration path from
the IPv4-based networks to the full IPv6 infrastructure. It assigns IPv6 addresses to clients and passes the IPv6
traffics through the IPv4 environment. The WGR-500-4P supports IPv4 tunneling (6to4 transition tunnel)
implementations for IoT connectivity.
Secure Firewall Protection
The denial-of-service attacks (DoS) attempt to consume resources and therefore deny users network and
application access. There are two types of DoS attacks – SYN floods and Ping of Death that consume actual
server resources, or those of intermediate communication equipment, such as firewalls and load balancers, and
the other, volume-based attacks like UDP/ICMP floods and other spoofed-packet floods that would saturate the
bandwidth of the attacked site.
The WGR-500 Series provides firewall to protect IoT devices against networking attack like denial-of-service
(DoS), and emerging malicious traffic before attacks can occur. With firewall protection, it prevents IoT network
from threats and keeps networking more secure.
