I've been having an issue in Packet tracer while trying to set up NAT on the ASA 5505. When sending a ping the outside router from an inside client, the address is not translated at the ASA, and as such the outgoing source remains the clients private IP. I am very new to networking, however from what I have read this should be working with the current config. Strangely, I can get NAT to work by changing the network object for the internal subnet to static NAT, then changing it back to dynamic interface, though this does not survive a reboot and the problem persists. This could be a simple issue or a lack in my knowledge, but I have been stuck trying to fix this for a few days now and haven't been able to make any progress. Any help would be greatly appreciated.
