Jo-Philipp Wich a9977eca91 firewall: allow local redirection of ports
Allow a redirect like:

config redirect
        option src 'wan'
        option dest 'lan'
        option src_dport '22001'
        option dest_port '22'
        option proto 'tcp'

note the absence of the "dest_ip" field, meaning to terminate the connection on the firewall itself.

This patch makes three changes:

(1) moves the conntrack module into the conntrack package (but not any of the conntrack_* helpers).
(2) fixes a bug where the wrong table is used when the "dest_ip" field is absent.
(3) accepts incoming connections on the destination port on the input_ZONE table, but only for DNATted
    connections.

In the above example,

ssh -p 22 root@myrouter

would fail from the outside, but:

ssh -p 22001 root@myrouter

would succeed.  This is handy if:

(1) you want to avoid ssh probes on your router, or
(2) you want to redirect incoming connections on port 22 to some machine inside your firewall, but
    still want to allow firewall access from outside.

This is the buildsystem for the OpenWrt Linux distribution

Please use "make menuconfig" to configure your appreciated
configuration for the toolchain and firmware.

You need to have installed gcc, binutils, patch, bzip2, flex,
make, gettext, pkg-config, unzip, libz-dev and libc headers.

Simply running 'make' will build your firmware.
It will download all sources, build the cross-compile toolchain, 
the kernel and all choosen applications.

You can use scripts/flashing/flash.sh for remotely updating your embedded
system via tftp.

The OpenWrt system is documented in docs/. You will need a LaTeX distribution
and the tex4ht package to build the documentation. Type make -C docs/ to build it.

Building your own firmware you need to have access to a Linux, BSD or MacOSX system.
Cygwin will not be supported because of the lack of case sensitiveness.

Sunshine!
