Cisco ISA550w Advanced NAT (Hairpinning)

I had my Cisco ISA550w configured with Advanced NAT so that we could access an internally hosted webserver using the external domain name. I (like a dummy) made some changes to the WAN interfaces and all the NAT configurations went byby. I know can no longer get it to work. I am sure I am just not setting up the NAT rules correctly, but I am about to toss the thing into the patomac. Anyone out there have this setup on an ISA or know how to do it. The KB is literally no help. Thanks in advace for any help and or assistance.
