+====== Actively monitor connections ======
+There are cases where you want to monitor a specific type of connection going from/to/through your router. The following example tracks DNS requests towards name servers.
+ \\
+''watch -tn5 "conntrack -L -p udp --dport **53** | sort -nrk3; echo; conntrack -L -p tcp --dport **53** | sort -nrk3"''
+ \\
+The number 53 refers to DNS. In the above case, it includes both udp and tcp. You can change this to any relevant port (for example, only 443) to change the command scope.
+For example:
+''watch -tn5 "conntrack -L -p tcp --dport 443 | sort -nrk3"''
+ \\
