How to build and run miniupnpd for your router running openwrt.
These instructions apply to the OpenWRT WHITE RUSSIAN (RC6) version.
My device is a Linksys WRT54G v1, used in pppoe mode.
More information about OpenWRT on http://openwrt.org/

First make sure that openwrt white russian RC6 is up and running on your
router device.

NOTES : Makefile.openwrt has been updated, following informations could
        be inacurate.
        The X-Wrt team made an ipk package out of miniupnpd,
        check the webpage : http://www.x-wrt.org/

* A. COMPILATION *

To Build, use your PC. I have been using the SDK but you might need
to compile the cross compiler yourself.

1. Get the SDK from http://downloads.openwrt.org/whiterussian/rc6/
   I used http://downloads.openwrt.org/whiterussian/rc6/OpenWrt-SDK-Linux-ppc-1.tar.bz2
   unpack somewhere and add the bin directory to your PATH environement :
   > tar xvjf OpenWrt-SDK-Linux-i686-1.tar.bz2
   > PATH=`pwd`/OpenWrt-SDK-Linux-i686-1/staging_dir_mipsel/bin:$PATH
   >  mipsel-linux-gcc --version
mipsel-linux-gcc (GCC) 3.4.4 (OpenWrt-1.0)
[...]

2. Get iptables 1.3.3 sources from http://downloads.openwrt.org/sources/iptables-1.3.3.tar.bz2
   unpack and compile libiptc.a
   > tar xvjf iptables-1.3.3.tar.bz2
   > cd iptables-1.3.3/libiptc/
   > make CC=mipsel-linux-gcc

3. Go to miniupnpd directory and edit the Makefile.openwrt to make
   IPTABLESINC and LIBS variables point to the correct directory.
   > make -f Makefile.openwrt
   > mipsel-linux-strip miniupnpd

That's it !


* B. INSTALLATION - USAGE *

1. copy miniupnpd and scripts to the device :
   > scp miniupnpd root@192.168.1.1:.
   > cd linux
   > scp iptables_init.sh iptables_flush.sh root@192.168.1.1:.
   > scp iptables_display.sh iptables_removall.sh root@192.168.1.1:.

2. log onto your router and edit the scripts in order to adapt to your
   configuration : EXTIF variable shoud be set to your external network
   interface. In my case it is ppp0

3. init tables :
   > ./iptables_init.sh

4. run the daemon :
   ./miniupnpd -i ppp0 -a 192.168.1.1 -p 5000 -U -d
   -d option is a debug option to prevent the program from going to
   background. It is usefull to see the debug messages and check if everything
   is ok.

5. Once you checked that everything is ok,
   you can set up a script in /etc/init.d etc...

   If you can build an ipkg package for miniupnpd, I'll be glad !
