Like all of Westell's products, the ProLine Dual Connect NAT Router is easy to install and can be configured in a matter of minutes using any standard Web browser through the Ethernet interface. It also is software upgradeable for maximum investment protection. It uses the industry-proven Point-to-Point Protocol over Ethernet (PPPoE/A) data protocol to connect to a service provider. And LAN network setup is a breeze through the use of Network Address Translation (NAT) and Dynamic Host Control Protocol (DHCP).
