I have an ASA 5505 configured with 3 interfaces, inside, outside and DMZ. Everything seems to be working except for DMZ access to the internet. What I want is for the DMZ to communicate to the inside network over port 1433, and the DMZ to communicate to the outside through port 80 and 443 only. Packet-tracer shows that traffic is being allowed, but I am still unable to access the internet from the DMZ. My ASA license is for an unrestricted DMZ. What am I missing here? Any help would be greatly appreciated. Here is my running config:
