 ## Objective

 Single DNS endpoint with failover:
- External: dns.xtrm-lab.org (DoT 853, DoH 443)
+- External: dns.xtrm-lab.org (DoT 853, DoH 8443)
 - Internal: 192.168.31.1 (all LAN clients)
 - Failover: Unraid AdGuard (192.168.31.4) as upstream backup

 ## Implementation Steps

- [ ] 1. Install AdGuard container on MikroTik
- [ ] 2. Configure veth interface with IP
- [ ] 3. Configure AdGuard upstreams
- [ ] 4. Enable DoT/DoH in AdGuard
- [ ] 5. Generate/configure TLS certificates
- [ ] 6. Update NAT rules (DoT/DoH → container)
- [ ] 7. Update DNS redirect rules (LAN → container)
- [ ] 8. Test internal DNS
- [ ] 9. Test external DoT/DoH
- [ ] 10. Update documentation

 ## Container Configuration

 - **Image:** adguard/adguardhome:latest
- **Root dir:** /usb1/adguard
- **Interface:** veth-adguard
- **Mounts:** Config persistence
+- **Version:** v0.107.71
+- **Root dir:** usb1/adguard/root
+- **Interface:** veth-adguard (172.17.0.2/24)
+- **Gateway:** 172.17.0.1
+- **Mounts:** agh-config, agh-work

 ## Network Configuration

-| Service | Port | Target |
-|---------|------|--------|
-| DNS | 53 | Container |
-| DoT | 853 | Container |
-| DoH | 443 | Container |
-| Web UI | 3000 | Container |
+| Service | External Port | Internal Target |
+|---------|---------------|-----------------|
+| DNS (UDP/TCP) | 53 | 172.17.0.2:53 |
+| DoT (TCP) | 853 | 172.17.0.2:853 |
+| DoH (TCP) | 8443 | 172.17.0.2:443 |
+| Web UI | 3000 | 172.17.0.2:80 |
+
+## NAT Rules
+
+```
+# DNS redirect for LAN
+chain=dstnat action=dst-nat to-addresses=172.17.0.2 to-ports=53 protocol=udp/tcp src-address=192.168.31.0/24 dst-port=53
+
+# DoT external access
+chain=dstnat action=dst-nat to-addresses=172.17.0.2 to-ports=853 protocol=tcp in-interface=eth1_WAN dst-port=853
+
+# DoH external access (using port 8443 to avoid Traefik conflict)
+chain=dstnat action=dst-nat to-addresses=172.17.0.2 to-ports=443 protocol=tcp in-interface=eth1_WAN dst-port=8443

+```
+
+## TLS Configuration
+
+- **Server name:** dns.xtrm-lab.org
+- **Certificate:** Let's Encrypt (valid until 2026-03-10)
+- **DoT port:** 853
+- **DoH port:** 443 (internal) / 8443 (external)
+- **Certificate location:** /mnt/user/appdata/claude-code/certbot/config/live/dns.xtrm-lab.org/
+
+## AdGuard Credentials
+
+- **Username:** admin
+- **Password:** admin123
+- **Web UI:** http://192.168.31.1:3000
+
+## Usage
+
+### Internal (LAN clients)
+Clients automatically use 192.168.31.1:53 via DHCP/NAT redirect.
+
+### External DoT (Android/iOS Private DNS)
+```
+dns.xtrm-lab.org
+```
+
+### External DoH
+```
+https://dns.xtrm-lab.org:8443/dns-query
+```

 ## Notes

- Using script from: https://github.com/maximpri/mikrotik-adguardhome
- Previous MikroTik containers removed (storage issues)
- Unraid AdGuard (192.168.31.4) remains as backup upstream
+- Old docker-bridge removed (was causing routing conflict)
+- Container network 172.17.0.0/24 conflicts with standard Docker on Unraid
+- Unraid AdGuard (192.168.31.4) used as primary upstream for ad filtering
+- Container starts on boot automatically
