Comodo firewall is blocking... What?

I just noticed that my firewall (CFP3) is doing a repetitive block ~every 2 minutes. The log is loaded with them. Below is a screenshot of a small part of them. Can anyone explain...

1- What is going on?

2- Should I stop this blocking action? If so, how?

 

That would be an all broadcast. If I remember right that is an all hosts broadcast. I think a different octet is all routers, maybe like .3 or .4

Edit. Oops. That is local traffic. You should not need to worry about it. One time I had an older 10base hub that was seeking to announce itself. I had to com into it to tell it to shut up. Unplug your devices one at a time to find the broadcaster. It looks like something on your network is asking maybe why you are transmitting. I am not aware of what program would do that. Maybe some SNMP application?

Hola Sul -- On my "network" there is just little old me & my faithful but aging computer.

I definitely want to STOP all this dadgummed logging, but HOW?

 

Logging is rather stupid in CFP. There seems no way to control the logging.

 

Hmm. Something on your computer is expecting others to be 'out there' locally. Here is a quick google finding, may not be the best but does sort of explain it's uses.

And about IGMP

I have networks, so I always assumed when I seen it that it was due to the hardware switches, hubs, routers, print servers, servers, etc.

Edit: You have a router, dsl modem or cable modem? Could be part of the equation.

 

Create a network rule for WOS (windows operating system) from 'Running Processes...' and block IGMP and leave logging unchecked for that rule. You can allow or disable logging for each network rule. Mine looks like this:



If you noticed, I set logging on for all except one rule. BTW, I do not use global rules because I find it easier to do everything via Application Rules.

IGMP was not on the Protocol drop-down list.

In any event I located the default global rule that was generating the repetitive log entries, & turned off logging. That did the trick.

However, I would like to know how you got IGMP on the protocol list.

 

Hi Bellgamin,

I'd agree with Sully. the source ip looks to be that of a router, so I assume you are behind one? It is probably your router sending the broadcasts.

@Adric - I see. 10 Q!
