a router does not buffer through traffic in a socket buffer (which is
what "TCP and UDP buffers" are) but on the interface queues and ipintrq,
which are typically 50 packets.
If this is the case you should see ipintrq drops listed
with
sysctl net.inet.ip.intr_queue_drops
and you could try to increase the size of that queue with something like
sysctl -w net.inet.ip.intr_queue_maxlen=100
