#21 nat portfw commands ignored silently

[Anonymous]

I've spent last 3 hours trying to get few UDP ports forwarded in simple NAT environment. I thought the process should be at max. 5 minute job. I was very wrong.

For reasons that I do not understand, any of the commands that I've tried (nat to-destination, dnat) do not make any rules into iptables. And what's wrong with this is that it does that completely silently. I would expect that if there are no complains, iptables were generated properly.

If you have ubuntu, there is a master config somewhere in /etc which make firehol not work at all (and silently) if you don't enable it.

If you have another distribution, try running:

firehol explain

and give it the dnat statement.
If it does not generate rules, you may have a broken BASH. Try reinstalling it.

If none of the above matches your case, tell me what you are trying to do and the statement that does not work for you.
