Access lan devices through zerotier and mikrotik

General Discussion
1

hello there
i have installed zerotier in mikrotik (HQ) to be able to reach any device in HQ device such servers ,NAS ,PCs etc .

i did this config
MY laptop ZT client 10.20.40.35
mikrotik zerotier client : 10.20.40.40 (zerotier firewall rules added )
LAN devices :192.168.1.0/24 via 10.20.40.40 (manage route in ZT dashboard)

i can ping from laptop to mikrotik zerotier IP
i can ping from mikrotik to laptop zerotier IP
but cannot ping any ip in lan :192.168.1.0/24

what is wrong with my config :
do i need to reset mikrotik config to default and starts over or i am missing somthing ??

Does the HQ Mikrotik router have allow input and allow forwarding rules on the firewall?

/ip firewall filter add action=accept chain=forward in-interface=zerotier1 place-before=0
/ip firewall filter add action=accept chain=input in-interface=zerotier1 place-before=0

port 6 to lan network switch

Is the ISP modem in bridge mode or is it configured as a router?
