Re: NAT performance

Hi,

A great paper !
But i have done some bandwidth tests which is quiet different ..
I know that NAT *is* expensive .. but i'm surprise that there no bandwidth difference between 20 client and 100 client.
So i would like to understand why this limit ?
Thx

This not a problem with the network card, because when i do the test
with only firewall routing i have a total bandwidth used near to
500Mbit/s.
But when i add an SNAT translation for each network (10) the total
bandwidth used is near 170Mbit/s.
So why this important difference without an with NAT ??


NAT *is* expensive. Have a look at the paper on netfilter performance tests and comparisons at http://people.netfilter.org/kadlec/nftest.pdf
