I encountered something I don’t quite understand, and I was hoping someone could enlighten me.
I set up Tailscale on my router with subnets, so I could remotely access my home network. This worked great. Then, at home, I was happily browsing the internet on my main PC, and decided to dial into another machine on my network. It couldn’t access it at all. Disconnecting Tailscale on my main PC restored lconnectivity.
I don’t understand what is happening here- the only thing I can think of is that my internet traffic was being routed through Tailscale, but I don’t have an exit node.
TL,DR: home PC sees Internet but not LAN when connected to Tailscale, why and how fix?
Yes, if Tailscale on your router is advertising routes, and your other devices while connected to Tailscale are picking up those advertised routes, they won’t be able to figure out how to get to your local network devices if both things are advertising the same routes.
