Too many connections on my router

Wokie · 2019-07-30T23:30:57.522Z

Anyone know from where are coming that connections? If i stay my server open for like 2 or 3 hours it gets like 50k connections on port 30120 wish is from my server.
There is a way to limit those connections? because at some point my router can’t handle and reset’s.
Im hosting my server on debian 9 server machine.
On my image first column is my lan ip,second column is my external ip and the third i think its who request the connection.
Thanks in advance

make sure firewall is up and working, and close any ports that are not being used

So i discover that connections are if i put the server show up on server list.
What i think is when people search for servers they send a request to see if my server is up,but then dont kill connection.is there a way to kill the connection after a certain time if no data sent?
