Pre version 8.3 to statically NAT an internal host to an external IP address you would use the following:
static (inside,outside) 18.104.22.168 192.168.100.10 netmask 255.255.255.255
This then means……
inside = the source interface for the NAT connection (assuming going from the inside to the outside)
outside = the translated interface for the NAT connection
22.214.171.124 = External IP address to which the internal host is translated to on the outside.
192.168.100.10 = Internal IP address from which is the original source of the traffic.
network mask 255.255.255.255 = Specfies that it is a single host, change this to 255.255.255.0 for a range of addresses for example.
