Nope, you're right. I should have read it a with a little more attention to
detail. Could be someone trying to run a client (bot) from that computer
like you suggested.
Are you sure? The SYN bit doesn't appear to be set, which I'd expect on
initial inbound TCP requests.
These all look to me like IRC *responses* - the outbound IRC traffic is
permitted but the server's response is being blocked. Someone could be
scanning you from the IRC port in an attempt to bypass your firewall,
but the many different source IP addresses argue against that.
I would check 184.108.40.206 for some kind of IRC client software -
including, most dangerously, a DDoS zombie, many of which register on
and are controlled via public IRC servers when active.
You may also want to add a rule blocking outbound traffic destined to
6666:6668/tcp and see what it reports.
