Hello,
i dont know why, but every day portsentry blocks my vm internet access because i got following port scan:
Dec 11 12:17:59 iobroker portsentry[527]: attackalert: UDP scan from host: 192.168.150.1/192.168.150.1 to UDP port: 54321 Dec 11 12:17:59 iobroker portsentry[527]: attackalert: Host 192.168.150.1 has been blocked via wrappers with string: "ALL: 192.168.150.1 : DENY" Dec 11 12:17:59 iobroker portsentry[527]: attackalert: Host 192.168.150.1 has been blocked via dropped route using command: "/sbin/route add -host 192.168.150.1 reject"

I dont know why and only this VM. The port Scan ip is my router fritzbox (Also it is the gateway ip). No Port Forwarding is activated.

Can someone help me to identify how my router can do a port scan?

I could deactivate the blocking to only warn, but i prefer to stop the port scan. Thanks
