Automatically turn on connection tracking?

[thomasmkling@xxxxxxxx]

Hello,

I do NOT want to type: (but it works correctly)
[1] iptables -A INPUT -m state --state NEW,INVALID,RELATED,ESTABLISHED,UNTRACKED,... -j A_TARGET_WHICH_REQUIRES_CONNTRACK

I just want to have:
[2] iptables -A INPUT -j A_TARGET_WHICH_REQUIRES_CONNTRACK


But [2] does not work, it fails because conntrack does not work: invalid conntrack, here:

ct = ip_conntrack_get((struct sk_buff *)skb, &ctinfo);
if (!ct) {
 DEBUGP("invalid conntrack \n");
	return;
}


Can someone please explain why? What I do wrong?
