2Conservative TCP state tracking
3CONFIG_IP_NF_CONNTRACK_CONSERVATIVE
4  This is an EXPERIMENTAL patch making TCP connection tracking behave 
5  more conservative.  If this option is enabled, it will only track 
6  connections which are started after ip_conntrack.o was loaded (or
7  your firewall booted).  It does no attempt on picking up old, 
8  previously established TCP connections.

10  This might help in some rare cases where you have problems with ACK
11  flooding filling up your connection tracking tables...

13  If unsure, say `N'.
