Unknown subnet in traceroute for HD2 Mini FW8.1.3

I was trying to do some troubleshooting on my network.
Realize that for FW8.1.3, it will always hop to 192.168.213.x subnet.

I’ve tried on different WANs and different unit but it still hopes to 192.168.213.x before going out to internet.
Any idea what subnet is this from?

FW 8.1.3

FW 8.1.2

Hi, a second hop should be from ISP gateway.
Have you checked what is your WAN IP ?
