I have two Internet circuits that I want to connect to the ASA. Prior to 8.2 I've been able to configure dynamic NAT for both interfaces and add two routes so that if one circuit went down outbound traffic would flow out of the second circuit. However with 8.3 I'm not sure how to do this.
route outside 0.0.0.0 0.0.0.0 126.96.36.199 1 - This is ISP gateway 1 (outside)
route outside 0.0.0.0 0.0.0.0 188.8.131.52 2 - This is ISP gateway 2 (outside2)
object network ANY
subnet 0.0.0.0 0.0.0.0
nat (inside,outside) dynamic interface - This NATs outbound traffic to the interface "outside"
How would I be able to add a second NAT entry so that if the outside circuit fails outbound traffic will flow out outside2
