I attempted to edit the trusted zone, but I was unable to resolve the issue. In the "Configure Rules and Zones..." Zones tab, I selected the Trusted zone entry, clicked Edit, and then "Add IPv4 address...". I tried entering different values, but they had no effect. I'm not entirely sure I understand what a local subnet is, but I added the IP address of my router, the computer's local IP address, and 192.168.0.0 (which I thought was my local subnet). I don't set up complex networks, I simply use the basic network features that come with Windows as they are simple and sufficient enough for my needs, and so my knowledge is fairly limited and I may be misunderstanding what you are explaining. Thanks for the continued support.
