Support for Dual-WAN request

[GoogleCodeExporter]

This is a request.

Is there any possibility of implementing Dual WAN mode as ASUS is already doing 
it. Reserve a port of choice in which we could configure as a second WAN port 
and with the same possibilities of configuration as the real WAN port, and a 
choice of how we wish it would work: failover or load-balance.

Thank you.

There is kind of support already. Although its not working 100%. 

I use a 3g connection for backup with its own router. Enable ARPping and add a 
static route 0.0.0.0 0.0.0.0 192.168.0.2  or whatever is the ip on the 
secondary router. Make sure to use a higher metric then 0 for this route.

It works when pri conn goes down, it removes the default route and leaving our 
route with the higher metric as the only default route. 

When primary connection comes back up the problem starts. It doesnt switch back 
until you hit "renew connection" for some reason.

Please note that this solution is ONLY for failover, not loadbalancing. I haven 
tried what behaviour i will get if both routes has the same metric. In theory 
it should do loadbalancing on packetlevel.
