I am trying to use SDM to configure a firewall on a Cisco 2811. This router has an MPLS connection, but also has a WAN interface that is NAT'd for web surfing and has a DMVPN spoke tunnel as a backup to the MPLS. I will attach some configs later, but I was wondering if anyone has experienced issues with multiple WAN connections.

This is the capability to configure your network to simultaneously connect to the outside world with two (or more) different connections provided by two different ISP's. There may be many reasons why you would want to do this, but the most common are:

Load Balancing


Increasing available bandwidth beyond what is offered by a single ISP.

While you can run all normal internet traffic across all WAN connections, you cannot currently do the following operations on any secondary WAN connections:

Remote Administration


PC Remote

Remote Access Portal
