Antonio Ojea 924553b7ee iptables don't do reverse DNS lookups ...

the iptables monitor was using iptables -L to list the chains,
without the -n option, so it was trying to do reverse DNS lookups.
A side effect is that it was holding the lock, so other components
could not use it.
We can use -S instead of -L -n to avoid this, since we only want
to check the chain exists.
