Where to find Cisco IOS 12.x

[Rogue]

I am trying to update my Cisco 2500 router to a version of IOS that supports NAT. I currently am running the Enterprise version of IOS 11.1. Does anyone know where I could get hold of IOS 11.2 or higher?

Did you ever find it? I'm running 11.1 myself...

You need a service contract with Cisco to get IOS updates.
