Most router are default configured to block ICMP traffic (pings) from the
internet WAN side. You 192.168.0.x range is considered internet if it is

The Block Anonymous Internet Requests is a feature is designed to prevent
intruders from attacking through the Internet. When it is Enabled, the
Router will drop both the unaccepted TCP request and ICMP packets from the
