I am running SVI ports on a Cisco 1812 router as additional WAN ports for a device that has up to 9 different ethernet WAN connections. Does anyone know if it is possible to run this kind of configuration on an SA540 that has 2 WAN ports and 8 'LAN' ports? I would also need the WAN ports to be presented as 'outside' in the firewall config and to be nat outside ports. My configuration works using route maps in nat and the application runs with a simple script to shut / no shut interfaces.
I am interested in the features / price point of this device but would need to run more than 2 WAN interfaces (one at a time or load balancing) for my application which is for mobile clients who have many varied options for physically connecting to the internet.
Many thanks in advance
