I have two sites interconnected by MPLS. Each site has an ASA and is connected to the internet. I'm trying to setup failover for internet connectivity and when on one site the ISP connection is down to route the internet traffic into MPLS and then to the ISP on the other site. The sla monitoring is working but the NAT is converting the traffic since it is not covered by NAT exempt rule and I do not see a way to exempt depending on the outgoing interface. Any suggestions?
