ZeroTier on RouterOS 7.5

Hi, I am following the step under https://help.mikrotik.com/docs/display/ROS/ZeroTier and have ZT installed on my CRS309-1G-8S+ running RouterOS 7.5. I am using this device in Bridge mode since I have another Router connected to WAN.

My goal is to be able to reach my home network which is 192.168.1.0/24 via ZT on the MikroTik.

I am able to enable ZT and the instance zt1 is connected to my ZeroTier network.

Following the steps in the manual, when I do zerotier/interface/print

Flags: R - RUNNING
Columns: NAME, MAC-ADDRESS, NETWORK, NETWORK-NAME, STATUS
NAME MAC-ADDRESS NETWORK NETWORK-NAME STATUS

0 R zerotier1 xx:xx:xx:xx:xx:xx 123456d8f68abcde able_abe OK

So, it appears everything is connected and working fine.

However, when I run /ip firewall filter add action=accept chain=forward in-interface=zerotier1 place-before=0

I get “no such item”

Is there something I am doing wrong?

Thank you!

Most logical answer would be there is no firewall rule 0 ?
Hence nothing can be placed before.
