How can i limit the number of nat session per user ?

I have a problem, people do not control their devices. infected android / infected laptop. On ours OpenWRT routers, when infected device is in the chilli DHCP, the Load is really huge... (i saw 900 yesterday)

if i stop chilli and wait 5 minutes, the load goes down. start again -> grow up immediatly.

I suspected an infected device but i see a lot of messages like that
