Looking at the docs http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.LVS-NAT.html#lvs_nat_performance

/"Don Hinshaw //dwh (at) openrecording (dot) com 04 Aug 2001
Cisco, Alteon and F5 solutions are all NAT based. The real limiting factor as I understand it is the capacity of the netcard, which these three deal with by using gigabit interfaces."/

Not using the director as firewall, just for load balancing:
What do you think is the LVS-NAT limit on a xeon dual core 1.60 Ghz with 2 GB of ram and gigabit connected?

The info on the documentation seems to be kind of old, does anybody have some fresh experience using nat and more than 20 real servers?

And about LVS-NAT?
Is it still the least scalable?

The LVS-NAT code from 2.4.x on is as fast as LVS-DR.

How many RS is the limit?

don't know of anyone who's tried that many at full blast.

If you're going to use LVS-NAT directors as firewalls, read the relevent sections of the HOWTO.
