-## Advanced: Private DNS Behind Routing Peers
-
-If your DNS server is on a private network accessible only through a routing peer, you need to set up network routes and access control in addition to the nameserver configuration.
-
-### Scenario
-
-You have:
-- **DNS server**: `192.168.0.32:53` on a private network
-- **Routing peer**: Can reach the `192.168.0.0/24` network
-- **Client peers**: Need to query this DNS through the routing peer
-
-### Setup Requirements
-
-#### 1. Configure the Nameserver
-
-Create a nameserver pointing to your private DNS:
-- IP: `192.168.0.32`
-- Port: `53`
-- Distribution groups: Your client peer groups (e.g., "Remote Developers")
-
-#### 2. Create a Network Route
-
-Set up a network route so clients can reach the DNS server:
-- Network: `192.168.0.0/24`
-- Routing peer: The peer that can access this network
-- Distribution groups: Same as your nameserver (e.g., "Remote Developers")
-
-#### 3. Configure Access Control
-
-Create an access control rule allowing DNS traffic:
-- Source: Client groups (e.g., "Remote Developers")
-- Destination: Routing peer's group
-- Protocol: UDP
-- Port: 53
-
-### DNS Forwarder Port
-
-<Note>
-**Technical detail**: When using private DNS behind routing peers, NetBird uses a DNS forwarder on routing peers. Starting with v0.59.0, this forwarder uses port `22054` (changed from `5353`) to avoid collisions with mDNS. For backward compatibility, port `5353` is used if any peer in your account runs below v0.59.0.
-</Note>
-
-This forwarder port is internal to NetBird's routing mechanism - you don't need to configure it, but may see it in logs or network traces.

+# Quickstart: Private DNS Behind Routing Peers
+
+If your DNS server is on a private network accessible only through a routing peer, you need to set up network routes and access control in addition to the nameserver configuration.
+
+## Scenario
+
+You have:
+- **DNS server**: `192.168.0.32:53` on a private network
+- **Routing peer**: Can reach the `192.168.0.0/24` network
+- **User peers**: Need to query this DNS through the routing peer
+
+## Setup Steps
+
+### Step 1: Configure the Nameserver
+
+Create a nameserver pointing to your private DNS:
+- DNS - Nameservers - Add nameserver - Custom DNS
+- IP: `192.168.0.32`
+- Port: `53`
+- Distribution groups: Your user peer groups (e.g., "Remote Developers")
+
+<Note>
+For detailed instructions on creating nameservers, see [Configuring Nameservers](/manage/dns/nameserver-groups).
+</Note>
+
+### Step 2: Create a Network Route
+
+Set up a NetBird Network so clients can reach the DNS server:
+- Networks - Add network
+- Network: e.g. "Office Network"
+- Add Resource: `192.168.0.32/32`
+- Distribution groups: Internal DNS
+- Routing peer: The always-on peer that can access this network
+
+<Note>
+For detailed instructions on creating network routes, see [Routing Traffic to Private Networks](/manage/network-routes/routing-traffic-to-private-networks).
+</Note>
+
+### Step 3: Configure Access Control
+
+Create an access control rule allowing DNS traffic:
+- Source: User groups (e.g., "Remote Developers")
+- Destination: Internal DNS (the resource group)
+- Protocol: UDP
+- Port: 53
+
+<Note>
+For detailed instructions on access control, see [Manage Network Access](/manage/access-control/manage-network-access).
