2.0 Creating a Tailscale Connection

Adding a Device

1. Go to your Tailscale Admin Console

2. Add new machine on user’s Tailscale

   • Add device > Linux Server
     
     
     
3. Generate install script
   
   
4. Copy and paste install script into user's Ubuntu Server VM (might have to manually type it out if ssh isn't configured // all one continuous line)
   

   EXAMPLE:
   curl -fsSL https://tailscale.com/install.sh | sh && sudo tailscale up --auth-key=tskey-auth-kEc5KrwcPv11CNTRL-rsE7QpaFhNeKRnTdUALKJgbkJ2Vg
   

   
   

5. Start up Tailscale in it:
   

   sudo tailscale up

6. Open the given login link and sign into Tailscale

Configure Advertised Subnet Routes

1. To connect to Tailscale as a subnet router, type in the following commands:

   Note - Change the advertise routes according to your subnet in a home lab environment
   *Any confusion on command syntax/structure can be clarified in Legend
   

   echo 'net.ipv4.ip_forward = 1' | sudo tee -a /etc/sysctl.conf
   echo 'net.ipv6.conf.all.forwarding = 1' | sudo tee -a /etc/sysctl.conf
   sudo sysctl -p /etc/sysctl.conf

2. To advertise subnet routes, type into the shell:
   

   CIDR Notation uses a slash (/) and a number to indicate the length of the network prefix (e.g. 10.0.0.0/24)

   sudo tailscale up --advertise-routes=[IP ADDRESS CIDR]

3. Enable the configured route on Tailscale
   • Edit route settings > Check the box with the IP route > Save
