+# Configuring default routes for Internet traffic
+
+NetBird introduces a way to redirect a peer's internet traffic through what is commonly known as exit nodes.
+This setup allows you to direct all internet-bound traffic from your devices through a specified routing
+peer.
+
+<Note>
+    This feature is available from Netbird version v0.27.0 onwards.
+</Note>
+
+## Concepts
+
+### Default Routes
+
+A default route, specified with the network address `0.0.0.0/0` for IPv4 and `::/0` for IPv6, directs internet-bound
+traffic from your devices
+through a designated routing peer.
+<Note>
+    Currently, IPv6 traffic is not supported and is blocked to prevent unintentional traffic leakage.
+</Note>
+
+### Routing Peer
+
+The routing peer functions as the exit node for the Internet traffic. Once configured, it automatically handles traffic
+it receives from connected peers, applying masquerading to ensure traffic appears to originate from the routing peer's
+public IP address.
+
+### Distribution Groups
+
+Peers within the specified distribution group are configured to send their Internet traffic to the routing peer over the
+VPN.
+This setup is activated as soon as the routing peer is connected.
+
+### Supported Clients
+
+The feature currently supports Linux, macOS, and Windows as client operating systems.
+
+### Routing Peer Selection
+
+Currently, this is exclusively configured through the dashboard and cannot be influenced by the client.
+
+## Configuration Steps
+
+### Access the Dashboard peers tab
+
+Navigate to the NetBird dashboard to begin the configuration process.
+

+         className="imagewrapper-big"/>
+</p>
+
+### Select the designated routing peer
+
+<p>
+    <img src="/docs-static/img/how-to-guides/netbird-peers-routing-peer.png" alt="routing-peer-view"
+         className="imagewrapper-big"/>
+</p>
+
+### Make the peer an exit node routing peer
+
+Hit the `Add Exit Node` button to configure the peer as an exit node routing peer.
+
+In the opened window, specify which peers should use the default route by assigning one or more distribution groups.
+These peers will automatically route their internet traffic through the routing peer upon its connection.
+
+
+<p>
+    <img src="/docs-static/img/how-to-guides/netbird-peers-add-exit-node.png" alt="add-exit-node-view"
+         className="imagewrapper-big"/>
+</p>
+
+Then hit the `Add Exit Node` button to complete the configuration.
+
+The routing peer is automatically set up to handle and route traffic it receives from connected peers. Masquerading
+remains enabled by default to mask the original source IP addresses.
+
+### Verify the configuration
+
+Verify the configuration in the peer view. The routing peer should now be marked as an exit node.

+         className="imagewrapper-big"/>
+</p>
+
+### DNS Configuration
+
+Add a DNS server with the match domain set to `ALL`.
+This is important, as locally configured DNS servers might not be accessible from the routing peer.
+This also helps to avoid leaking the client's location.
+
+See [Manage DNS in your network](manage-dns-in-your-network).
+
+## High Availability
+
+Like for other network routes, high availability configurations are supported for default
+routes. Refer to
+the [Creating Highly Available Routes](routing-traffic-to-private-networks#creating-highly-available-routes)
+section for more information.
