4096 is an arbitrary limit imposed by /proc/sys/net/ipv4/ip_conntrack_max. And this limit is derived from the systems total amount of memory at startup time. This is something totally different than the hardware-imposed limit once you run out of memory. The description just wants to tell you that you can set the software limit to a higher value, as long as you consider your amount of free memory. You should never set the software limit to something higher than your hardware does. > Because the FAQ clearly states that 64Mb memory corresponds to 4096 > connections.
