I have 3 deco p9's in wi-fi router mode. They are an isolated lan that is off my "main" network.

The IP given to the Deco is a static 192.168.30.10
The gateway it access is 192.168.30.1

I have internal Deco LAN ip set to 192.168.90.1 serving clients locally with DHCP

I am noticing in my network logs that every 40 seconds there is an attempt to access 192.168.1.8 from the Deco IP. 
There does not seem to be any configuration that could be causing this. I am hoping someone might have an idea why this could be happening. 

I have firewall rule that blocks this but I would prefer not to have logs getting cluttered with this.
