Okay, knowing that your line is 10Mbit adds some more information. 1. How do you know the problem is not with your ISP ? Can you download at 10Mbit under any circumstances ? 2. What makes you think is it NAT which is causing the performance problem ? Does the problem go away if you do not use NAT ? 3. How busy is your box (what load average does uptime show) ? 4. Are you getting any kernellogging messages about conntrack table full etc ? 5. What speed CPU / how much memory is in the netfilter machine ? Antony. -- This is not a rehearsal. This is Real Life.
