OK, I think logging can be considered at part solved.

Actually, starting a ulogd in the namespace does work; I was trying to
use NFLOG with ulogd1 which does not. When I disabled IPv6 and used
ULOG I got iptables ouput for the appropriate namespace.

This needs verifying with ulogd2 to check that it works for NFLOG also.

In addition I just did this:
  sudo ip netns exec fw /etc/init.d/ulogd restart

So I need to check if we can start multiple ulogd instances and write
to separate log files.
