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?

    Just throwing this out there: Are you using a separate VPN for your PC? For instance, my PC has a commercial VPN and Tailscale. Talescale connects me to the remote server for ssh/sftp etc, while my VPN connects to everything else. I had to do some tinkering to get them to both work simultaneously. Without the tinkering, Tailscale would not connect to the server.

    If you are just using Tailscale with no other VPN then disregard this, and take the advice form others here.

      I have a commercial VPN, but I am not connected. What tinkering did you have to do?

        My commercial VPN has a VPN kill switch and an Advanced Kill switch in case the regular kill switch wasn’t enough…lol. Unchecking both of those allowed Tailscale to connect to my remote server for ssh/sftp/administration, while the commercial VPN covers everything else. The only thing I guess you need to keep in mind is to engage the Kill Switch when downloading your Linux ISOs. Do a leak test beforehand.
