I am receiving this error when performing a packet trace on my ASA 5505. It is pointing to a dynamic nat rule on my outside interface to my public IP as to the reason for the drop. Not sure why this would stop the traffic. I have an access rule to allow any traffic from the IP but still get the error. Any ideas as to what my issue is would be greatly appreciated.

I added this to the config as I thought it may have been the issue but it didn't help.
