two rules in my INPUT chains are:
-A INPUT -s 63.110.21.51 -m state --state NEW -j LOG --log-prefix
"PLAYNC_NEW " --log-level debug
-A INPUT -s 63.110.21.51 -m state --state NEW -j DROP

My router is keeping the following logs

judging from the destination UDP ports and the TTL--i would say that
they are traceroute packets.

So, why are you logging it?  It's just the normal white noise of
ordinary Internet traffic.  Nothing to care about.

Maybe you should tell them to go away instead of remain silent.
(Replace the -j DROP with a -j REJECT --reject-with
icmp-port-unreachable.)
