MikroTik constantly try to check ICMP to local IP on WAN interface?

RouterOS General

Hi,

currently I have realized via logging of MikroTik router itself traffic to internet via filter rule on output chain that router constatly try to reach IP 172.16.16.2 on WAN via ICMP…I have a log full of this 20 times per seccond (!):

output: in:(unknown 0) out:ETH2 WAN, proto ICMP (type 0, code 0), 188.75.146.98->172.16.16.2, len 540

RoS 7.2.1 on RouterBOARD 750G r3

Does anyone have an idea what is going on there? Or how to identify the source of this anomaly? I have no nework 172.x.x.x defined in my config, no IP 172.16.16.2 if I search in my config backup.

Thanks!

Without seeing how you have tortured your config, not possible.
