My scannning results: I am not willing to reset my router to factory settings to check if the test might run through then as suggested above. I have changed quite a few settings in it though. Changed some of it's settings like in somewhere there are boxes for DNS servers that I have changed to OpenDNS ones. Disabled wireless connections to router box. Changed the Firewall settings from Medium to High. These ISP connection provided router boxes have quite a lacking documentation or advices how to configure them. But I might have done some other changes too. I have also Windows DNS client service disabled on my computer. Test also shows the DNS server addresses that seem to be right with both ISP connection and VPN connection testing of what to be expected.
