I love this new rype of router that has dual wan ports. We had some significant issues with our Comcast Broadband connection that were totally resolved by combining our ATT DSL and Comcast broadband into our office network. It has a capablity of using one or the other as a backup or dual simultaneous use for load sharing. We went with the load sharing use of both wans.Just what we needed. This mode also maintains service even if the other WAN goes down. It also has VPN tunneling but we didn't need that at the moment. WE highly recomend this router even if you only need one WAN port.
