Hello all again!

Since I've setup some strict rules for my firewall, I periodically
get the foolowing lines in messages:

As you can see, the sequence is quite stable - every ~5min 8 messages one
after another in 6 sec intervals.

What could it mean? (besides it has something to do with the firewall)
And which process emits requests which become denied?

Thanks
