Hi John,

yeah, ignore hostap-utils.
It looks like iptables is kind fo misconfigured or modules are not there.
I've never seen this trouble in my 0.7.5 installations. Right now, I just have a 0.8 installation to test on, but there everything is running, as I expect it to.
So let's see, how to figure out, what you're missing. ;)

Does "dmesg" state anything about iptables?
What is the output of "lsmod | grep ip_"?
And the output of "modprobe iptable_nat" looks like?

Greets, Markus

The results your looking for are as follows:

WARNING: All config files need .conf: /etc/modprobe.d/hostap-utils, it will be ignored in a future release.

iptables v1.4.8: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)

Perhaps iptables or your kernel needs to be upgraded.

 

At this point, im not worried about the /etc/modprobe.d/hostap-utils warning, that’s next after the iptables issue.

 

Thanks again,

John

Hi John, everybody,

I will give it a try. I guess the "1.0" value might represent some indicator of a metric. Nothing to worry about in my opinion.
About iptables.
Please try the " iptables -nvL -t nat" command and post the output.
The iptables man page gives you more info about the options, but in short:
-n : numeric output, just to make sure, we'll see IPs, no host names
-v : as always - give us as many hints as possible ;)
-L : List , you already used that one
-t : table, for specific exercises, iptables uses specific tables. One default one is "nat", clearly the one you intend to investigate/troubleshoot

Good luck, I hope this helps a little.

Best regards,
Markus

OK.....
10.1.0.1 is the gateway. The graphic was obtained by using OLSR. I believe
the arrows mean that the specific node has a route to the other node that it
is attached to, and the 1.0, I could not tell you. Ive never found
information on that part of the plugin for OLSR. And you are correct in that
I am using a /16 on this particular network.
 
I have tried modprobe iptable_nat and modprobe ip_nat_ftp. All the sites Ive
read, this was the only suggestion found and that was one site of MANY. 
 
Scripting the firewall rules is not a problem.
 
The goal is to allow traffic from the mesh network to pass through the
gateway and eventually, lock down the traffic. What I would like to do,
eventually, is attached in the diagram. We are planning on hundreads of
these nodes if not more. The three node environment is just a proof of
concept.
 
Thanks again,
John
