Does advertise-routes work on Synology?


I am trying to add a couple of subnet routes to Tailscale on a Synology DS218+. The Tailscale command executes without error. However, I am not able to ping any ip’s in the subnets that were added. A created a temporary ubuntu machine in the same subnet and issued the exact shame command and I can ping the added subnets from the clients. IP forwarding is enabled on the Synology.

Thanks for the help.

It’s possible but very tedious to set up currently and varies based on which version of DSM and which Synology kernel.

Our next release makes it automatic, though.

Some background is in Document how to enable IP forwarding · Issue #52 · tailscale/tailscale-synology · GitHub



Can you let me know how to enable subnet routing on Synology with the 1.8 release? I don’t seem to be able to find it. And, even if I use the iptables commands that I used before, routing doesn’t seem to work anymore.
