Hi , I have enabled ICMP inspection I might have deleted the config line beofre posting it here..
When I Run this with echo-reply or information-request - its fails with the NAT error
packet-tracer input GUEST icmp 192.168.80.1 0 1 184.108.40.206 xml
When done with just echo everything shows a tick on the packet tracer..
Echo reply would not work as a synthetic packet as is used by packet-tracer since there is no record of the echo request having been in through the device.
Again, I highly recommend to use tcp as a test through the firewall and in a way that matches real world traffic flows.
@Marvin Rhoads Thank you for you r continued help , I found out the issue and what fixed it was I needed to put the nat after auto source dynamic and now traffic is flowing :)
