I am having trouble configuring the TailScale client for subnet routing on Synology NAS devices in two sites. Use case is to allow thin clients in Site 1 to connect to remote desktop servers in Site 2.
Site 1: 192.168.22.0/24
Client started with “sudo tailscale up --advertise-routes=192.168.22.0/24 --snat-subnet-routes=false”
Site 2: 192.168.24.0/24
Client started with “sudo tailscale up --advertise-routes=192.168.24.0/24 --snat-subnet-routes=false”
Gateway devices are Draytek routers. Static routes are configured for 192.168.xx and 100.64.0.0/10 via NAS devices.
From a test machine with TailScale client installed, I can connect to remote desktop serves in the remote site as expected. I cannot however, connect from the thin clients for which there is no tailscale client.
DSM version is 7.1-42661 Update 2 on both NAS devices.
I have checked that the TUN device exists (Access Synology NAS from anywhere · Tailscale)
From the NAS devices I cannot ping local or remote tailscale IP addresses.
Any and all assistance much appreciated.
