["John M. Brown" <jmbrown () ihighway net>]

Ok, I am blue in the face now...  

Is there a cisco release naming / feature 
expert in the house ??:)

What version of IOS properly supports
IP, BGP, NAT, ISL and NetFlow

where ALL of this stuff works.

I tried 11.1(18)CC it has the Netflow stuff
but ISL is broken 

arggggg
