I am trying to setup IP SLA for my WAN interface and want the NAT to be setup to when the link goes down the NAT will switch over.
Here is the config:
version 15.5 track 1 ip sla 10 reachability interface GigabitEthernet0/0 ip address 10.1.10.1 255.255.255.0 ip nat inside ip virtual-reassembly in duplex auto speed auto ! interface GigabitEthernet0/1 ip address 74.92.x.x 255.255.255.252 ip nat outside ip virtual-reassembly in shutdown duplex auto speed auto ! interface GigabitEthernet0/2 ip address 66.219.x.x 255.255.255.252 ip nat outside ip virtual-reassembly in duplex auto speed auto ! ip forward-protocol nd ip nat inside source list 7 interface GigabitEthernet0/2 overload ip route 0.0.0.0 0.0.0.0 66.219.x.x track 1 ip route 0.0.0.0 0.0.0.0 74.92.x.x 10 ip sla 10 icmp-echo 188.8.131.52 source-interface GigabitEthernet0/2 frequency 10 ip sla schedule 10 life forever start-time now access-list 7 permit any
I have tried multiple different configurations with the NAT, but cannot seem to get both in there and working once the link fails over.
