I could read the code to check the exact syntax out but I will ask here,
hopefully to the benefit of all:

So the iptrap4 command adds the matching traffic to the ipset named in
src, for the duration which is the second parameter?

Then business as usual.
Could this also be used to setup e.g. port knocking without the daemon?
In which case a different command name than iptrap4 might be nice?
e.g. something like:
ipset4 dynamic trap 600 inface dsl0 proto tcp dport 22 log "TRAP SSH"
