Skynet Since installing Diversion and Skynet my log is full of [Blocked] Extremely Many Entries. False or positive? Kind of scares me.

Rt-AX86U with Merlins 386.1 My log is blowing up and in Web Gui if i press the links to alienVault they don't have much info. I'm not sure how to interpret this. Am i being hammered with that much attacks constantly? I have X:ed out my public IP thats all. the rest is as my log say.
Could there be a device on my Lan that has been hacked that are causing this? All i can se is my routers IP as Destination so i don't know so much.
I have only been running like 2 or 3 days since Skynet was reset. Here are some links from alienvault.
https://otx.alienvault.com/indicator/ip/45.155.205.76 https://otx.alienvault.com/indicator/ip/45.155.205.160 https://otx.alienvault.com/indicator/ip/192.241.220.36 https://otx.alienvault.com/indicator/ip/45.155.205.158
Before this it was the same except then alienvault actually had many "threat findings" in AlienVault "Se the pic with only SRC". I had outgoing threats also from myLinux Laptop then. Is there some way for me to investigate further? Is there some entware script or app that can help me understand theese logs?
A While ago with a crappy F-Secure Sense router my Philips Hue bridge was hacked and my daughters Lenovo Tab 10. After this i have Restored them. On her Tab i ran Lenovos Restore utilityprogram, it got totally wiped. On the Hue bridge i removed the link to the bridge, changed the passw on Hue web site and resetted bridge. I reseted all my devices from google, and reinstalled my Laptop with the Manufacturers Restore utility USB key.

Sorry for the bad format in my post. i tried to fit as much as i could within the 1000 signs limit.

I deleted a whole lot information to try to shorten it down.

The thing is that the firewall is constantly getting hammered. I's always like this.
i will attach a pic in this post just to show

Very normal for inbound blocks. But if you do not have any ports or services open on the WAN side of your router, the built-in firewall would have blocked these anyway. So I disable inbound blocking. If I ran an OpenVPN server or did port forwarding, I would leave inbound blocking enabled.

No i never have anything open on the wan side.
I never connect to my router from internet. I have no Ai protection or or Ai disks on and no DDNs, no port forward, trigger or anything that could connect to me.

I just made some changes by disabling inbound blocking too, also dropped Pixelserv Std to Lite and haven't regretted the changes. Always concerned my old AC56 is being stressed with all this stuff running for little or no reason.

Some people don’t realise that when they enable logging, they see new log entries that normally don’t show in the log - when logging is disabled.

Does what you're saying mean that the blocklist(s), updated periodically in Skynet, only block outbound connections? Because if the router will block everything that Skynet blocks inbound, why does the Skynet blocklist update?

In my personal setup, yes, it only blocks outbound connections that my devices might try to make to a banned IP.

In the general sense, the router's built-in firewall will block all unsolicited inbound traffic, unless you have a port listening on the public WAN interface. It won't block traffic when it's configured to accept traffic on a particular port (e.g. OpenVPN, ssh, https, port forwards, etc.). In these situations Skynet will block with a vengeance any attempted inbound connection from a banned IP to one of your open, listening WAN ports. This is good.

Since I don't have any public listening WAN ports, I don't feel I need inbound blocking with all its unnecessary inbound block messages. But I DO want logging of outbound blocks. If Skynet supported logging only outbound blocks, I would leave inbound blocking enabled without logging. But Adamm rejected that idea because he thought it added complexity.

@dave14305 One other thing. So since SkyNet reports typically thousands of blocks, this means that it's seeing these unsolicited connection attempts before the router's firewall. In other words SkyNet is in front of the router's firewall?

Mostly. It works at the earliest possible point in the firewall traffic flow, before rules that the router creates.

so if one runs skynet can one disable the built in firewall with no ill effects?

sorry to hijack but isnt running built in firewall and skynet firewall kind of the firewall equivalent of double natting?
