 General changes
 ---------------
 
-The IP firewalling and NAT code has been replaced again.  The new
-netfilter software (including ipfwadm and ipchains backwards-
-compatible modules) is currently distributed separately.
-
 If you have advanced network configuration needs, you should probably
 consider using the network tools from ip-route2.
 
+Packet Filter / NAT
+-------------------
+The packet filtering and NAT code uses the same tools like the previous 2.4.x
+kernel series (iptables).  It still includes backwards-compatibility modules
+for 2.2.x-style ipchains and 2.0.x-style ipfwadm.
