sudo tailscale login

4. Advertise exit node

Select a host machine as the exit node. This represents the device you will use as the VPN.

# Enable IP forwarding
echo "net.ipv4.ip_forward = 1" | sudo tee -a /etc/sysctl.d/99-tailscale.conf
echo "net.ipv6.conf.all.forwarding = 1" | sudo tee -a /etc/sysctl.d/99-tailscale.conf
sudo sysctl -p /etc/sysctl.d/99-tailscale.conf

# Increase UDP compatibility
NETDEV=$(ip -o route get 8.8.8.8 | cut -f 5 -d " ")
sudo ethtool -K $NETDEV rx-udp-gro-forwarding on rx-gro-list off
printf "#!/bin/sh\n\nethtool -K %s rx-udp-gro-forwarding on rx-gro-list off \n" "$(ip -o route get 8.8.8.8 | cut -f 5 -d " ")" | sudo tee /etc/networkd-dispatcher/routable.d/50-tailscale
sudo chmod 755 /etc/networkd-dispatcher/routable.d/50-tailscale

# Advertise as an exit node
sudo tailscale set --advertise-exit-node=true
sudo tailscale up

Finally, open the menu of the machine labeled "Exit Node" from Tailscale dashboard and select the "Use as exit node" option in "Edit route settings...".

5. Connect to the exit node

You can successfully use your VPN service by connecting to the exit node from different devices.

# Choose exit node
sudo tailscale set --exit-node=100.100.10.10
sudo tailscale up

You can find the exit node address from the Tailscale dashboard or on the server with the following command.

# See Tailscale address
sudo tailscale ip

TIP: Stop being an exit node

You can stop being an exit node as follows.

# Stop being an exit node
sudo tailscale set --advertise-exit-node=false
sudo tailscale up

TIP: Stop using exit node

You can stop using the exit node as follows.

# Stop using the exit node
sudo tailscale set --exit-node=
sudo tailscale up
