Oops - that should be /proc/sys/net/ipv4/ip_conntrack_max of course.
Incidentally, if you don't change this value, it's calculated so that it uses
approximately 5% of the system's memory (in other words, you should be able
to increase the conntrack table capacity by a factor of about 20 on a system
which isn't using memory for anything else).
