Hi,

I just noticed some problems in the iptables error reporting, the patch
attached should fix them. If nobody finds any problem on it, I'll push
it to git.

Some work to improve iptables error reporting would be nice, I'll see if
I can have a look into this issue. BTW, it would be nice to have some
kind of tool to automate the testing of command line interface. Thus, we
can ensure that the tool output remains consistent. I started some tool
for the conntrack-tools but it is still very simple.
