Subnet pinging not working for MacOS

Hello!
I’ve started setting up my Tailscale network, but I’m having issues with subnets.

Here is my 3 devices, I gave them easy names for clearness.
The router is a Synology running DSM7.

DO you have “Use Taislcale Subnet” option enabled on your macOS?

Yes, that option is enabled.

What network firewall you are using ? Can you please try adding “randomizeClientPort true” in your ACL, there are some firewalls which blocks connections over specific UDP port.
