If you stop gnunetd properly (sigterm / sighup instead of sigkill), it 
*tells* currently connected peers to stop sending traffic. If you don't, 
these other peers will assume for up to another 30 minutes that they are 
still connected to you and keep sending you messages.

Even if you properly shut gnunetd down, other peers will still send tiny (!) 
probes to check if you may be back and available for the time that you 
specified in your gnunet.conf under HELOEXPIRES, which is typically 24h, but 
you can reduce it down to 1h or increase it to much, much longer. After that 
time, all the UDP traffic should stop. 

But again, you will see *lots* of traffic if you do not shutdown gnunetd 
properly since peers will continue sending you lots of messages (queries, 
potentially content,etc.) whereas the probes over the 24h period should be so 
little traffic that you should barely notice.
