Hi, i have two ISP connected to Cisco ASA.
When one ISP go down we manually shift default route to 2nd carrier. in pre 8.3 our PAT worked fine, but in 8.3 ASA our PAT doesnt work. and even if we change default route to 2nd Carrier, NAT/PAT of first carrier keep triggering and same is shown in packet tracer.
What to do to make sure 2nd carrier NAT/PAT trigger as soon i route traffic to 2nd carrier interface?
nat (Inside,ISP1) source dynamic INSIDE-PORTS-ALLOW interface service obj-tcp-eq-http obj-tcp-eq-http
nat (Inside,ISP2) source dynamic INSIDE-PORTS-ALLOW interface service obj-tcp-eq-http obj-tcp-eq-http
Above is example,
When i change default route to
route ISP2 0.0.0.0 0.0.0.0 1.1.1.1
Traffic drops and keeps nating with ISP1 interface.
Please suggest some solution.
