Can't ping through Synology subnet router

I have Tailscale setup on a Synology NAS, and have it set to advertise it’s local subnets

sudo tailscale up --advertise-exit-node --advertise-routes=,

I am remote and connected to the same TS network. I can ping the TS IP just fine, and can web into a device on the remote subnet: BUT CAN NOT ping that device or any device on the remote subnet.

Any idea on what could be blocking pings?

I have enabled subnet router on a Windows machine on the same subnet and CAN PING through that subnet router. It’s just the Synology subnet router that won’t let pings through!

It turns out the problem was the Synology firewall. I had to allow traffic to the Tailscale network of

It’s all working now! Hopefully this helps someone in the future.

Hello, I’ve got same problem here. Can you explain where it needs to be allowed? The firewall in web UI is disabled.

In synology, go to control panel, security, firewall, then edit your firewall rules.
