# Exit Nodes
## On the node
Register the node and make it advertise itself as an exit node:
```console
$ sudo tailscale up --login-server https://headscale.example.com --advertise-exit-node
```
If the node is already registered, it can advertise exit capabilities like this:
```console
$ sudo tailscale set --advertise-exit-node
```
To use a node as an exit node, IP forwarding must be enabled on the node. Check the official [Tailscale documentation](https://tailscale.com/kb/1019/subnets/?tab=linux#enable-ip-forwarding) for how to enable IP forwarding.
## On the control server
```console
$ headscale nodes list-routes
ID | Hostname | Approved | Available | Serving
1 | ts-head-ruqsg8 | | 0.0.0.0/0, ::/0 |
2 | ts-unstable-fq7ob4 | | 0.0.0.0/0, ::/0 |
# Note that for exit nodes, it is sufficient to approve either the IPv4 or IPv6 route. The other will be added automatically.
$ headscale nodes approve-routes --identifier 1 --routes 0.0.0.0/0
Node updated
$ headscale nodes list-routes
ID | Hostname | Approved | Available | Serving
1 | ts-head-ruqsg8 | 0.0.0.0/0, ::/0 | 0.0.0.0/0, ::/0 | 0.0.0.0/0, ::/0
2 | ts-unstable-fq7ob4 | | 0.0.0.0/0, ::/0 |
```
## On the client
The exit node can now be used with:
```console
$ sudo tailscale set --exit-node phobos
```
Check the official [Tailscale documentation](https://tailscale.com/kb/1103/exit-nodes#use-the-exit-node) for how to do it on your device.
