NAT performance

[snobs]

Hello, I need a NAT gateway. Unfortunately I cannot find any information about NAT performance of Fortigate. Well, I expect up to 2000 clients with up to 1 Gbit/s throughput being source nated against one public IP. So, what do I need? I guess, an e.g. FG-200B is way to overpowered for this?

I would look at the Fortigate model information. There is some information on throughput performance. It might lead you in the direction you are looking for.

What you should look for in the specs is the " firewall throughput" . Doing a source address translation does not take (noticeably) more power than firewalling alone. But do take the figures with a grain of salt, as always with marketing material. For instance, the 60C is rated with 1000/950 Mbps fw throughput, but I would never, ever put 2.000 users behind it. Funny enough that at the moment we are discussing the performance gap between a 110C and a 200B which is rumoured to be filled with an upcoming 100D. Depending on your time schedule it might pay to wait for it for, say, a couple of weeks.
