ASA 5505 Access Rules / NAT not allowing inbound traffic
I have a new ASA 5505 10 User appliance connecting a 20Mbps Cable Internet connection to the Internal network. I have configured Access rules and NAT, but obviously do not have something right as the ASA is not passing http, https or smtp traffic to the internal server. In a possibly related condition, I am able to authenticate the Client-Access VPN connection through the ASA, but cannot talk to anything inside over the connection. Any feedback would be appreciated as this Windows/Mainframe guy is stumped.... config is below.
Notes:-------------------- ---------- ---------- ---------- ---------- ---------- ---------- ---------- ---------- ---------- ---
X.X.X.A is the outside interface IP of the ASA (Static IP)
X.X.X.B is another public IP address in our external range not directly assigned to an interface. (Static)
Presently, all services (http, https, smtp) are serviced by a single server at 192.168.0.51
Remote users will connect using Cisco VPN Client 5.x through Server 2008 NPS (RADIUS)

I am on a business connection known to support the services. The PIX that this ASA is replacing was performing all of these services, at least until the APC failed and a surge nailed it. I can also plug-up a cheap-o Netgear router and everything works fine, so I have narrowed it down to the ASA config itself.
All I am seeing in the logs is that the session has been:
6 Jun 25 2008 20:24:47 302013 <REMOTEIP> 192.168.0.51 Built inbound TCP connection 166 for outside:<REMOTEIP>/2102 (<REMOTE IP>/2102) to inside:192.168.0.51/443 (X.X.X.A/443)
6 Jun 25 2008 20:25:17 302014 <REMOTEIP> 192.168.0.51 Teardown TCP connection 166 for outside:<REMOTEIP>/2102 to inside:192.168.0.51/443 duration 0:00:30 bytes 0 SYN Timeout
The Packet Tracer is showing the packet passes successfully to the endpoint both inside and outside. It's weird, so I am sure I am missing something simple.

I'm sorry, You lost me. Those are not valid commands, what are you recommending?
Thanks for your help

I have added the inspect http, but cannot find anything for https or smtp. Do those inspection maps need to be created somehow?
config t
policy-map global_policy
class inspection_default
inspect http
inspect https
inspect smtp
end
I'm wondering if the CBAC engine requires inspection of these packets.
policy-map global_policy
class inspection_default

Errors received below... I am not seeing smtp or https as options in the ASDM GUI either. Do they need to be added somewhere?

I am having the same problem as above. What was done to resolve this issue? Thanks.
And, do the firewall logs give any indication of the failure if the traffic is making it to the unit?
