Configuring Tailscale to allow access to your exit node local IP addresses/network

By default, you cannot access the network of your exit node but can be achieved fairly easy by using the Tailscale advertise subnets option

SSH / Connect to the exit node you would like to set up,

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

As I don’t run a firewalld on my local devices, I did not have to set up firewalld with masquerading, in case you do:

firewall-cmd --permanent --add-masquerade

Now its time to advertise our local subnet

sudo tailscale up --advertise-routes=192.168.1.0/24 --advertise-exit-node

now head over to the route settings of the node we just used to advertise its routes to

That’s it! when you use this node as an exit host you can now access its local networks!
