I am having trouble setting up RDP access to a LAN host from the WAN. I have used a few cisco guides to create the ACL/NAT rules to try to make this work, but I have been unsuccessful.
When I use the "packet trace" function it shows the packets are being dropped by the deny all ACL on the bottom of the "outside" ACL list. I have created an "any any" rule and moved it above this deny all rule for testing purposes, but it still shows as being blocked by the deny all / implicit rule.
Below is the running config:
