Subnet routes on Synology with version 1.8.3


I recently updated Tailscale to version 1.8.3 from version 1.6 on my Synology NAS. Previously, subnets routes worked as long as you issued several iptables commands when the NAS is booted. However, after upgrading to Tailscale 1.8.3 subnet routers are no longer working. Any ideas?

May I know what the OS of your subnet relay is? Also, if you can share your domain and Tailscale IP details on, we can help you further.

The relay is on Synology DSM 6. I will send the details. Thanks for your help.
