Tailscale configuration with static routing

Network

Router 1 - 10.0.0.1
Router 2 - 192.168.100.1

These routers each have their own internet and are configured with static routing and that works fine to share the plex server over LAN. The plex server is on Router 2. I have zero issues with any network connections outside of tailscale.

I have tailscale installed on Router 1 and I had both 10.0.0.0/24,192.168.100.0/24 advertised. I can access the entire 10.0.0.0 network but I can not access any of the 192.168.100.0 network through tailscale.

Do I have to configure anything on Router 2? I just assumed if I can access Router 1 with tailscale and static routing works without tailscale that everything should be fine.

I have remote access turned on with my plex server but that uses the internet from Router 2 (obviously) my end goal is to successfully connect to my LAN on Router 1 and connect to the plex server (locally) with tailscale.

All is good now. Had a typo on my advertising for Router 2.
