We could use the CT target to specify a fixed timeout, but since
it is only used for creating the conntrack entry, the timeouts
wouldn't be refreshed for received packets. This doesn't sound
very useful. Of course the target could also modify existing
connections, but that doesn't fit into the concept very well.
