While looking into this suggestion, I see that SLIP, PLIP,
and PPP depend on NETDEVICES, and they use some netdev
interfaces, so they appear to be more like net devices
than protocols even though they are called
protocols in Kconfig text, so I am leaving them alone
for now. Don't hesitate to correct me....
Any comments on this new version?

Thanks,

A few people dislike that the Networking Options menu is inside
the Device Drivers/Networking menu. This patch moves the
Networking Options menu to immediately before the Device Drivers
menu, renames it to "Networking options and protocols", & moves
most protocols to more logical places.

Notes:
- IrDA & Bluetooth subsystems include protocols & drivers, yet
they are displayed under Networking protocols. I don't see
much good reason to split them up. (See, this is an example
of why the Networking Options and Network Drivers were close
together....)
- SLIP, PLIP, and PPP option names say that they are protocols,
but they are sort of a hybrid device and protocol, and they
use network device interfaces, so they remain listed under
Network devices.

- bool "Network packet filtering (replaces ipchains)"
- ---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
