I continue to get the error above on my ASA5510. I have a dynamic NAT rule in place to translate everything coming from the inside network to the outside address of the ASA. Pings and other traffic (i.e. DNS requests) are obviously getting through because all of the errors are returning packets. What could be the cause of this? Thanks.
You have a public IP assigned to the ASA (but no default gateway).
You should add:
route outside 0 0 207.98.185.x
After this check that you can PING something on the internet from the ASA itself:
If succesful, you should have internet from the computers.
Try adding this:
And try to PING from the internal machines 18.104.22.168
