Minimwatch cannot see the server on qnap

The 255.255.255.0 value for subnet mask is OK. The active subnet is not the same as the subnet mask. What is the IP address of the server? If this starts with 192.168.1. this would mean your subnet setting is OK and the problem is likely to be caused by a firewall or antivirus program on the PC. It sometimes happens that the PC has its LAN connection listed as Public rather than Private and this can cause inbound traffic to be blocked by your PC firewall.
