I have a ATT DSL connection at a location and have set up an ASA behind it and have it working properly.  I also opened up 3389 to point to the internal host.  I used whatismyip.com to find out the public I was getting and tried to remote in to no avail.  I want to set one of my statics to one of my hosts but the static mapping does not work right with PPOE connection.  How can I do so?  config below...

your acl is incorrect and you need static nat port translations.

Example. http to host triton, RDP to host zeus

static (inside,outside) tcp interface 3389 10.10.0.50 3389 netmask 255.255.255.255
static (inside,outside) tcp interface www 10.10.0.30 www netmask 255.255.255.255
access-list outside_access_in permit tcp any interface outside eq www
access-list outside_access_in permit tcp any interface outside eq 3389
access-group outside_access_in in interface outside

You need to add a static NAT rule:
static (inside,outside) zeus (or you would use an ip) [outside ip] netmask 255.255.255.255
http://www.tech-recipes.com/rx/149/static-map-to-internal-device-on-a-pix/

And your inbound access list will not allow that traffic - the ACL is applied BEFORE the NAT rule so you need to permit the 3389 traffic to the outside interface, not the address of the server.
