Fail2Ban and unauthorized invites

Sorry I can't answer your question, I'm posting more details as I was about to post the same. However, I'm posting part of log instead. There is nothing in there for fail2ban to "grab" on. Wonder if anyone know what it is and how to get it stopped..

I'm about to give up here and instead create "white" list on router/firewall

Code:
