Help, Easy ASA5505 Port forward

Help, Easy ASA5505 Port forward was created by ajass
I have read dozens of posts on how to configure NAT and ACL and after trying just about everything I still can't get this.
Simple setup, simple need.
I have 1 static IP from ISP, 1 web server, 5 workstations. Workstations are on same VLAN as server.
All I need is for any internet computer to be able to surf my web server using my outside static IP. How hard can this be!? Please help!
Here's what I can do:
1. Surf the internet
2. Surf the web server from inside (10.10.10.5)

I really need this device up and running, any help is greatly appreciated! Thanks!

Remove the following NAT configurations:
static (outside,inside) 10.10.10.5 xx.xx.45.28 netmask 255.255.255.255
static (inside,outside) xx.xx.45.28 10.10.10.5 netmask 255.255.255.255
and replace with:
static (inside,outside) tcp interface 80 10.10.10.5 80
Then enable your ACL on the outside interface:
access-group INBOUND in interface outside
static (outside,inside) 10.10.10.5 xx.xx.45.28 netmask 255.255.255.255
static (inside,outside) xx.xx.45.28 10.10.10.5 netmask 255.255.255.255
and replace with:
static (inside,outside) tcp interface 80 10.10.10.5 80
Then enable your ACL on the outside interface:
access-group INBOUND in interface outside
