Cisco ASA 8.3 And Later: Allowing FTP Through The Firewall To An FTP Server

I had a consultant ask me to allow FTP in so he could send a large file over to a server on our network.  All he needed to do was start the FTP and walk away.  Ok, here is how I did this on the ASA, 8.3 and after code:
ASA# config t
ASA(config)# object network obj-10.10.10.150
ASA(config-network-object)# host 10.10.10.150
ASA(config-network-object)# nat (inside,outside) static 5.5.5.50
ASA(config-network-object)#exit
ASA(config)# access-list outsideIN permit tcp any host 10.10.10.150 eq ftp 
ASA(config)#exit
