You have those ports open that I disabled access to (1029, 1028, 1027).. You can see Kerio GUI is listening at them in your pic.. That is what my concern was (about those service ports).. Visit https://www.grc.com/x/ne.dll?bh0bkyd2 to test your service ports and see what you have open (click on the link, then proceed, then service ports to test)
