Wat exactly are you trying to access, is it the outside interafce of the ASA?? If it is any other IP address in the same subnet that your isp has provided, then you would need to plug a host on the inside interface and do static nat for it, then only you would get a response for random ports on it.
plug a host on the inside interface, assign an ip, lets say 10.0.16.2, then you would need the static:
static (inside,outside) 64.38.xx.xx 10.0.16.2
Then try the connection, it should then show you everything opened.
