Hi,
I segment my network into three networks. And at some point I was not able to ping my default gateway address any more.
I am able to access any IP address on 192.168.100.0/24 network from any network on OpenWrt router such as Raspberry Pi, except IP address of ISP router.
It must be some configuration issue, because when I reset settings I am able to access ISP router and hence the Internet.
Network config:
