Installing an ASA 5510 to replace a NS25 firewall.  Just trying to configure it simply to allow internal users access to internet, mail to flow in and out, and remote desktop to our terminal server for now.  Following other examples and posts it seems I have things right but obvioiusly not.  (I've masked my real IPs)

Router IP: 13.14.15.226
Outside IP: 13.14.15.227
Inside IP: 172.16.200.1
Mail Outside: 13.14.15.229
Mail Inside: 172.16.200.11
RDP Outside: 13.14.15.228
RDP Inside: 172.16.200.18

Start by removing the acl from the inside interface
   no access-group Inside_access_in in interface Inside

Then tell us exactly what does work and what does not.

That seems to have done it.  I haven't been able to test if webmail or remote desktop work yet.  I'll do that a little later this week.
