This is the network topology:
ping from 100.86.227.9 to 192.168.100.156 got no responses, I can not see any icmp request on exit node’s tailscale0 interface, it seems that traffic relay only works for public ip address but not private address.
configuration of 100.86.227.9:
configration of 100.122.102.75 (the exit node)
tailscale up --advertise-routes=10.0.1.0/24 --accept-routes -accept-dns=false --advertise-exit-node
