Does anyone know if you can "Dual Home" on the ASA 5505? Our current Internet connection is a 6mb pipe using 20x.x.x.x. We are installing a bigger pipe from another provider 7x.x.x.x but need to keep the "small" pipe in place as we transtition from one IP range to the other. Thus, the need to Dual Home.
The ASA does not support dual homing if both ISP links are active at the same time. You can configure a backup scenario like this tough:
If you have a router available, you could terminate the links on the router and do PBR on it.
