Try DaRemote: ssh, remote commands, Linux Dashboard, it's handy. It does ssh-related things with the click of a button rather than the keyboard, but it also comes with a terminal.
Your current pattern allows all users from 192.168.0.1 to 192.168.0.255. On CIDR format, that would be
AllowUsers *@192.168.1.0/24
The /24 cover the 192.168.1 part (each octet cover 8 bits), check the expanded pattern.
There are various approaches actually, and you probably want to use a public key instead so even if a device in your network is compromised, brute-forcing is not possible.
