+description: |
+  Learn how to configure your primary and satellite deployments so that they
+  share a hostname using geo DNS or anycast.
+state: alpha
+---
+
+By default, the primary deployment and satellite deployments have different
+access URLs. Using two access URLs can confuse engineering teams when it comes
+time to determine which one they should use for Coder.
+
+To prevent confusion, Coder supports an optional unified hostname configuration
+where the primary deployment and all satellite deployments share a hostname. All
+users who access Coder use the same URL; meanwhile, your DNS server or anycast
+configuration ensures that users are still accessing a deployment that is near
+to them geographically, offering low latency when connecting to their
+workspaces.
+
+GeoDNS (also known as _geographical split-horizon DNS_) is a DNS load balancing
+technique that helps users connect to their geographically nearest servers
+without relying on anycast IP routing. This guide will focus on GeoDNS setup,
+though it will still work with anycast routing.
+
+## Requirements
+
+You will need the following:
+
+- A primary access URL (e.g. `https://primary.example.com`)
+- One or more satellite access URLs (e.g. `https://sydney.example.com`,
+  `https://london.example.com`)
+- A "unified" access URL (e.g. `https://coder.example.com`). If you are using
+  GeoDNS, you should set the default backend to the primary access URL. Set the
+  backend for each region with a satellite to the corresponding satellite access
+  URL or IP address
+- A TLS certificate for the primary deployment that has both the primary
+  hostname and the corresponding unified hostname
+- A TLS certificate for _each_ satellite with the satellite's hostname and the
+  corresponding unified hostname
+
+> Please note that:
+>
+> - If you are using cert-manager, you can add hostnames to a certificate by
+>   including them in the `spec.dnsNames` section.
+> - We recommend maintaining a separate "regional" hostname or IP address for
+>   each primary or satellite so you can access them explicitly to aid in
+>   debugging. This guide will walk you through preserving the existing regional
+>   access URL.
+
+## Configure a unified access URL on Coder
+
+1. Configure your geo DNS or anycast routing so the primary Coder deployment and
+   all satellites share a single hostname, as well as their individual
+   hostnames. (We have provided instructions on
+   [how to create a GeoDNS load balancer on Cloudflare](#create-a-geodns-load-balancer-on-cloudflare)
+   below.)
+
+1. In the primary Helm values file, set `coderd.alternateHostnames` to your
+   primary hostname and unified hostname:
+
+   ```yaml
+   coderd:
+     alternateHostnames:
+       - "primary.example.com"
+       - "coder.example.com"
+   ```
+
+1. In _each_ of your satellite deployments' Helm values file:
+
+   1. Set `coderd.satellite.accessURL` to your unified access URL (this value
+      will be used as the default URL).
+
+   1. Set `coderd.alternateHostnames` to your satellite's specific hostname and
+      your unified hostname:
+
+      ```yaml
+      coderd:
+        alternateHostnames:
+          - "satellite.example.com"
+          - "coder.example.com"
+      ```
+
+1. Redeploy your primary and satellite deployments with your new Helm values.
+
+1. Once you've fully deployed your primary and satellite deployments, log into
+   Coder on your original primary access URL and go to **Manage** > **Admin**.
+
+1. On the **Infrastructure** tab, set the **Access URL** field to your unified
+   access URL (e.g. `https://coder.example.com`).
+
+1. If you've enabled logins via OIDC, log into your OIDC identity provider's
+   admin page and update Coder's redirect URI to reflect your new access URL
+   (e.g. `https://coder.example.com/oidc/callback`).
+
+1. If you've enabled Git account linking, log into each Git provider and update
+   Coder's redirect URI to reflect your new access URL.
+
+At this point, all users should be able to access Coder via the unified access
+URL. Your DNS server will automatically route users to their nearest
+geographical primary or satellite deployment for low latency. OIDC logins should
+work as expected across all domain names, including the primary access URL.
+
+## Create a geo DNS load balancer on Cloudflare
+
+To create a geo DNS load balancer on Cloudflare:
+
+1. Log in to Cloudflare, and select the domain on which you want your geo DNS
+   hostname to exist.
+
+1. Expand the **Traffic** app on the sidebar and select **Load Balancing**.
+
+1. Enable **Load Balancing** if you haven't already.
+
+1. Ensure that your Cloudflare plan has enough origin servers for your
+   deployments; you will need one origin server for the primary deployment and
+   one for each satellite deployment.
+
+1. Click **Create Load Balancer**.
+
+1. Enter the unified hostname you wish to use (e.g. `coder.example.com`).
+
+   ![Enter hostname](../../assets/admin/cloudflare-geodns/hostname.png)
+
+1. **Optional:** Disable Cloudflare proxying by **unchecking** the orange cloud.
+   We recommend disabling Cloudflare proxying when using satellites, since
+   proxying adds additional hops that will increase latency.
+
+1. Click **Next** to proceed.
+
+1. For the primary deployment and _each_ satellite deployment, do the following
+   steps:
+
+   1. Click **+ Create an Origin Pool**.
+
+   1. Set the **Pool Name** and **Pool Description**.
+
+   1. Specify a single origin with **Origin Address** set to the hostname or IP
+      address of the deployment. Then, set the **Weight** to **1**.
+
+   1. Click **Configure co-ordinates for Proximity Steering** and drag the
+      marker to roughly where the deployment is located geographically.
+
+   1. Click **Save**.
+
+   ![Create pool](../../assets/admin/cloudflare-geodns/create-pool.png)
+
+1. Once you have completed the above steps for the primary and each satellite
+   deployment, ensure that all origin pools have been assigned to the load
+   balancer.
+
+1. Set the **Fallback Pool** to your primary deployment's origin pool.
+
+   ![Pools](../../assets/admin/cloudflare-geodns/pools.png)
+
+1. Click **Next** until you reach the **Traffic Steering** step.
+
+1. Set the traffic steering policy to **Proximity steering**.
+
+1. Click **Next** until you reach the **Review** step.
+
+1. Review your changes; then, click **Save and Deploy**.

+description: Learn how to enable TUN devices for VPN usage within Coder.
+state: alpha
+---
+
+By default, Coder workspaces do not contain a TUN device, making it difficult to
+run a VPN. However, Coder offers an admin configuration setting that, when
+enabled, automatically creates a TUN device within all Kubernetes [CVM-enabled
+workspaces](cvms/index.md).
+
+> At this time, Coder does not support TUN devices for other workspace types
+> (such as EC2 or Docker).
+>
+> If you're working with EC2 workspaces, we recommend enabling privileged mode
+> in the workspace provider settings, which will allow users to create their own
+> TUN device.
+
+## Enable TUN devices in Coder
+
+To enable TUN devices for Kubernetes [CVM-enabled workspaces](cvms/index.md):
+
+1. Log into Coder, and go to **Manage** > **Admin**.
+1. On the **Infrastructure** page, scroll down to the **Workspace container
+   runtime** section.
+1. Under **Enable TUN device**, click the toggle to switch this feature **On**.
+1. Click **Save workspaces**.
+
+![Enabling TUN devices](../../assets/admin/tun.png)
+
+The new setting will apply to workspaces **after** you rebuild them.
+
+Users running workspaces with TUN devices should be able to run VPN clients
+within their workspace as long as they have root (or `sudo`) access within their
+workspace.
+
+> We've tested this feature using the [Tailscale](https://tailscale.com/) VPN
