I have recently purchased a asa 5505 and I am trying permit rdp on the outside interface to a host on the inside (10.15.1.50) I am also trying Nat a dhcp range on the outside to my inside interface. THe dhcp range 192.168.2.128/27
Yes, PAT is used only for outbound traffic and you cannot establish a inbound connection to a PAT IP address, for a Inbound connection you need to One to One NAT / Static. with a ACL permitting the traffic.
the replies you got about static and acl are correct. Regarding nat/global statements, always have in mind that you must use global command on a lower security level and the nat command on the higher security level.
