+	bool "Networking support"
+	---help---
+	  Unless you really know what you are doing, you should say Y here.
+	  The reason is that some programs need kernel networking support even
+	  when running on a stand-alone machine that isn't connected to any
+	  other computer.
+	  
+	  If you are upgrading from an older kernel, you
+	  should consider updating your networking tools too because changes
+	  in the kernel and the tools often go hand in hand. The tools are
+	  contained in the package net-tools, the location and version number
+	  of which are given in <file:Documentation/Changes>.
+
+	  For a general introduction to Linux networking, it is highly
+	  recommended to read the NET-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>.

+	---help---
+	  These are the protocols used on the Internet and on most local
+	  Ethernets. It is highly recommended to say Y here (this will enlarge
+	  your kernel by about 400 KB), since some programs (e.g. the X window
+	  system) use TCP/IP even if your machine is not connected to any
+	  other computer. You will get the so-called loopback device which
+	  allows you to ping yourself (great fun, that!).
+
+	  For an excellent introduction to Linux networking, please read the
+	  Linux Networking HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>.
+
+	  If you say Y here and also to "/proc file system support" and
+	  "Sysctl support" below, you can change various aspects of the
+	  behavior of the TCP/IP code by writing to the (virtual) files in
+	  /proc/sys/net/ipv4/*; the options are explained in the file
+	  <file:Documentation/networking/ip-sysctl.txt>.
+
+	  Short answer: say Y.

+
+menuconfig NETFILTER
+	bool "Network packet filtering framework (Netfilter)"
+	---help---
+	  Netfilter is a framework for filtering and mangling network packets
+	  that pass through your Linux box.
+
+	  The most common use of packet filtering is to run your Linux box as
+	  a firewall protecting a local network from the Internet. The type of
+	  firewall provided by this kernel support is called a "packet
+	  filter", which means that it can reject individual network packets
+	  based on type, source, destination etc. The other kind of firewall,
+	  a "proxy-based" one, is more secure but more intrusive and more
+	  bothersome to set up; it inspects the network traffic much more
+	  closely, modifies it and has knowledge about the higher level
+	  protocols, which a packet filter lacks. Moreover, proxy-based
+	  firewalls often require changes to the programs running on the local
+	  clients. Proxy-based firewalls don't need support by the kernel, but
+	  they are often combined with a packet filter, which only works if
+	  you say Y here.
+
+	  You should also say Y here if you intend to use your Linux box as
+	  the gateway to the Internet for a local network of machines without
+	  globally valid IP addresses. This is called "masquerading": if one
+	  of the computers on your local network wants to send something to
+	  the outside, your box can "masquerade" as that computer, i.e. it
+	  forwards the traffic to the intended outside destination, but
+	  modifies the packets to make it look like they came from the
+	  firewall box itself. It works both ways: if the outside host
+	  replies, the Linux box will silently forward the traffic to the
+	  correct local computer. This way, the computers on your local net
+	  are completely invisible to the outside world, even though they can
+	  reach the outside and can receive replies. It is even possible to
+	  run globally visible servers from within a masqueraded local network
+	  using a mechanism called portforwarding. Masquerading is also often
+	  called NAT (Network Address Translation).
+
+	  Another use of Netfilter is in transparent proxying: if a machine on
+	  the local network tries to connect to an outside host, your Linux
+	  box can transparently forward the traffic to a local server,
+	  typically a caching proxy server.
+
+	  Yet another use of Netfilter is building a bridging firewall. Using
+	  a bridge with Network packet filtering enabled makes iptables "see"
+	  the bridged traffic. For filtering on the lower network and Ethernet
+	  protocols over the bridge, use ebtables (under bridge netfilter
+	  configuration).
+
+	  Various modules exist for netfilter which replace the previous
+	  masquerading (ipmasqadm), packet filtering (ipchains), transparent
+	  proxying, and portforwarding mechanisms. Please see
+	  <file:Documentation/Changes> under "iptables" for the location of
+	  these packages.
+
+	  Make sure to say N to "Fast switching" below if you intend to say Y
+	  here, as Fast switching currently bypasses netfilter.
+
+	  Chances are that you should say Y here if you compile a kernel which
+	  will run as a router and N for regular hosts. If unsure, say N.

+	bool "Network packet filtering debugging"
+	depends on NETFILTER

+	  You can say Y here if you want to get additional messages useful in
+	  debugging the netfilter code.
+
+config NETFILTER_ADVANCED
+	bool "Advanced netfilter configuration"
+	depends on NETFILTER
+	default y
+	help
+	  If you say Y here you can select between all the netfilter modules.
+	  If you say N the more ununsual ones will not be shown and the
+	  basic ones needed by most people will default to 'M'.
+
+	  If unsure, say Y.
+
+config BRIDGE_NETFILTER
+	bool "Bridged IP/ARP packets filtering"
+	depends on BRIDGE && NETFILTER && INET
+	depends on NETFILTER_ADVANCED
+	default y
+	---help---
+	  Enabling this option will let arptables resp. iptables see bridged
+	  ARP resp. IP traffic. If you want a bridging firewall, you probably
+	  want this option enabled.
+	  Enabling or disabling this option doesn't enable or disable
+	  ebtables.
+
+	  If unsure, say N.
