You should have at least the following:

> interface Serial 0

> description Outside interface

> ip address x.x.x.x y.y.y.y

> ip nat outside

> interface Ethernet0

> description Inside interface

> ip address 192.168.150.x y.y.y.y

> ip nat inside

> ip nat inside source static 192.168.150.251 155.55.134.25

Looks like you might have gotten the IP addresses around the wrong way going by your description.
