I use Centos 7 with directadmin on a VPS

Ever since I installed CSF+LFD and Fail2ban I see these incoming udp (which gets blocked) lines on port 33445 every 10 seconds in my /var/log/messages. All these have the same source aswel.
What is this connection and where is it coming from? Why is it every 10 seconds?

When I look up the ip6 address on different sites they tell me its a so-called private ipaddress, does this means this ip6 is a local address?


I was hoping someone overhere could tell me more about this or point me in the right direction.

Thank you and much appreciated!

Have you tried what it says in CSF configuration at UPD OUT:

Allow outgoing UDP ports
To allow outgoing traceroute add 33434:33523 to this list

First, thanks for your reply!

Please correct me if I'm wrong, but arent these incoming UDP connections? Port 33445 on incoming (outgoing aswel btw) UDP is obviously blocked in CSF and I dont see any reason to open it, other than for the traceroute functions.

I'm getting these every 10 seconds, I've searched google quite a bit ofcourse. But I cant find any reason for why this is happening.

Any information is appreciated
