I would guess you need to look into the kernel commands, lsmod, insmod, modprobe, etc.  If the kernel you are using has the iptable-nat module built, but not not installed, you should be able to load it using modprobe.  You can use lsmod to see what kernel modules are preloaded, but honestly, I can't think of a command that tells you what tells you what's available (built, but not loaded).  Look in /lib/modules, or maybe modprobe has some options. 

Another fun challenge is to build your own kernel with the modules you need built and loaded.  There are lots of examples and references for this process, so I wont repeat them here. Search on "bitbake -c menuconfig omap-console-image" and go from there.  Identifying the modules you need to enable using menuconfig is also a learning process, but there are examples online for building network bridges using iptables.

Hello All,

I am some what of a linux newbie. I am using an overo earth board with a tobi duo that  I am trying to do some internal routing from one NIC to the other, and from what I can see the kernel-module-iptable-nat seems to be missing and is necessary for my goal. As far as I know. I am using one of the prebuilt images Angstrom 2010.7-test-20101115 overo ttyS2. I can't seem to do opkg install. I do not think this is proper way to install kernel modules. I looked through the archives and have come up empty. Can someone point me in the right direction? What commands do I need to be using? What is the proper way to install these modules? Is there something I am missing ?

Thanks in advance.
