+	depends on NETFILTER_XTABLES
+	depends on NETFILTER_ADVANCED
+	select NF_DEFRAG_IPV4
+	select NF_DEFRAG_IPV6 if IP6_NF_IPTABLES
+	help
+	  This option adds a `TPROXY' target, which is somewhat similar to
+	  REDIRECT.  It can only be used in the mangle table and is useful
+	  to redirect traffic to a transparent proxy.  It does _not_ depend
+	  on Netfilter connection tracking and NAT, unlike REDIRECT.
+
+	  To compile it as a module, choose M here.  If unsure, say N.
+
+config NETFILTER_XT_TARGET_TRACE
+	tristate  '"TRACE" target support'
+	depends on IP_NF_RAW || IP6_NF_RAW
+	depends on NETFILTER_ADVANCED
+	help
+	  The TRACE target allows you to mark packets so that the kernel
+	  will log every rule which match the packets as those traverse
+	  the tables, chains, rules.
+
+	  If you want to compile it as a module, say M here and read
+	  <file:Documentation/kbuild/modules.txt>.  If unsure, say `N'.

+config NETFILTER_XT_TARGET_TCPMSS
+	tristate '"TCPMSS" target support'
+	depends on (IPV6 || IPV6=n)
+	default m if NETFILTER_ADVANCED=n
+	---help---
+	  This option adds a `TCPMSS' target, which allows you to alter the
+	  MSS value of TCP SYN packets, to control the maximum size for that
+	  connection (usually limiting it to your outgoing interface's MTU
+	  minus 40).
+
+	  This is used to overcome criminally braindead ISPs or servers which
+	  block ICMP Fragmentation Needed packets.  The symptoms of this
+	  problem are that everything works fine from your Linux
+	  firewall/router, but machines behind it can never exchange large
+	  packets:
+	        1) Web browsers connect, then hang with no data received.
+	        2) Small mail works fine, but large emails hang.
+	        3) ssh works fine, but scp hangs after initial handshaking.
+
+	  Workaround: activate this option and add a rule to your firewall
+	  configuration like:
+
+	  iptables -A FORWARD -p tcp --tcp-flags SYN,RST SYN \
+	                 -j TCPMSS --clamp-mss-to-pmtu

+config NETFILTER_XT_MATCH_CLUSTER
+	tristate '"cluster" match support'
+	depends on NF_CONNTRACK
+	depends on NETFILTER_ADVANCED
+	---help---
+	  This option allows you to build work-load-sharing clusters of
+	  network servers/stateful firewalls without having a dedicated
+	  load-balancing router/server/switch. Basically, this match returns
+	  true when the packet must be handled by this cluster node. Thus,
+	  all nodes see all packets and this match decides which node handles
+	  what packets. The work-load sharing algorithm is based on source
+	  address hashing.
+
+	  If you say Y or M here, try `iptables -m cluster --help` for
+	  more information.
+
+config NETFILTER_XT_MATCH_COMMENT

+	  and DCCP flags.
+
+	  If you want to compile it as a module, say M here and read

+	depends on (IP6_NF_IPTABLES || IP6_NF_IPTABLES=n)
+	depends on NETFILTER_ADVANCED
+	help
+	  This option adds a `hashlimit' match.
+
+	  As opposed to `limit', this match dynamically creates a hash table
+	  of limit buckets, based on your selection of source/destination
+	  addresses and/or ports.
+
+	  It enables you to express policies like `10kpps for any given
+	  destination address' or `500pps from any given source address'
