 # VPN
 
-On [vpn.qo.is](https://vpn.qo.is) we run a [Tailscale](https://tailscale.com) compatible VPN service. To use the service, you can use a normal Tailscale client with following additional configuration:
-
-| Option | Recommended value | Description |
-|--------|-------------------|-------------|
-| `accept-routes` | enabled (flag) | Accept direct routes to internal services |
-| `exit-node` | `100.64.0.5` (lindberg) or `100.64.0.6` (cypriaspitz) | Use host as [exit node](#exit-nodes) |
-| `login-server` | `https://vpn.qo.is` | Use our own VPN service and not tailscale's upstream one |
-
-
-⚠️  Currently, if the client is in an IPv6 network, the transport is broken. See [#4](https://git.qo.is/qo.is/infrastructure/issues/4) for progress on this.

 ## User and Client Management
