[c-nsp] 7304 impressions

[M.Palis]

What IOS are you using now?

We try to replace  a C7400 with a C7304 and we try various IOS releases 
including 25S without success. We are doing NAT for ADSL users (around 2000 
nat entries). With 25S we found a problem with CEF. Disabling CEF the router 
was able to pass traffic but CPU was high . Enabling CEF a lot of traffic 
was dropped. I did not figured out why.
