Hello

I have 40Mbit/s internet uplink
Average transfer 25Mbit/s
- 3957 users
On machine: 
- CPU 3.2GHz P4 +HT enabled
- 2GB RAM
- Intel GB cards

Machine is doing nat/dnat for each user so there is 3957 DNAT/SNAT ip pairs (private to public and vice versa)

Machine load is 0.1 avg

And no any problems :)

Update: I obtained some data from the mentioned ISP: 
- Backbone: 16Mbit 
- average transfer 700kB/s (5600kbit/s) 
- about 20 users 
- CPU Celeron 333 
- no performance problems noticeable 
 
The only unanswered question remains the user count (20 vs 400 is not really 
comparable). 
 
Yours sincerely, 
Peter
