🌐 DNS Access Setup Guide
Current Status
✅ Firewall Fixed: Ports 3000 and 8080 are now open
⚠️ DNS Configuration: Needs to be updated to point to public IP
The Problem
Your DNS houseofprayer.ddns.net is currently pointing to:
- Internal IP: 192.168.10.130 (only works on your local network)
- Should point to: 170.254.17.146 (your public IP for external access)
Solution: Update No-IP DNS
Option 1: Using No-IP Website (Recommended)
-
Login to No-IP:
- Go to https://www.noip.com/login
- Login with your account
-
Update Your Hostname:
- Go to "My Services" → "DNS Records"
- Find
houseofprayer.ddns.net - Click "Modify"
- Update the IP address to: 170.254.17.146
- Click "Update"
-
Wait for DNS Propagation (5-15 minutes)
Option 2: Install No-IP Dynamic Update Client (DUC)
This automatically updates your DNS when your public IP changes:
# Download and install No-IP DUC
cd /usr/local/src/
sudo wget http://www.noip.com/client/linux/noip-duc-linux.tar.gz
sudo tar xzf noip-duc-linux.tar.gz
cd noip-2.1.9-1/
sudo make
sudo make install
# Configure (enter your No-IP username and password when prompted)
sudo /usr/local/bin/noip2 -C
# Start the service
sudo /usr/local/bin/noip2
# Make it start on boot
echo '@reboot /usr/local/bin/noip2' | sudo tee -a /etc/crontab
Router Configuration
You MUST configure port forwarding on your router:
Port Forwarding Rules Needed
-
Frontend Access:
- External Port: 3000
- Internal IP: 192.168.10.130
- Internal Port: 3000
- Protocol: TCP
-
Backend API:
- External Port: 8080
- Internal IP: 192.168.10.130
- Internal Port: 8080
- Protocol: TCP
How to Configure (General Steps)
- Login to your router (usually http://192.168.10.1 or http://192.168.1.1)
- Find "Port Forwarding" or "Virtual Server" section
- Add the rules above
- Save and reboot router if needed
Common Router URLs
- Netgear: http://192.168.1.1 or routerlogin.net
- TP-Link: http://192.168.0.1 or http://tplinkwifi.net
- Linksys: http://192.168.1.1
- ASUS: http://192.168.1.1 or router.asus.com
- D-Link: http://192.168.0.1
Testing After Setup
1. Test from Server (Local)
curl http://localhost:3000
curl http://localhost:8080/api/songs
2. Test from Local Network
curl http://192.168.10.130:3000
curl http://192.168.10.130:8080/api/songs
3. Test DNS Resolution
nslookup houseofprayer.ddns.net
# Should show: 170.254.17.146
4. Test External Access (from phone/another network)
Current Configuration
Server Information
- Public IP: 170.254.17.146
- Internal IP: 192.168.10.130
- DNS: houseofprayer.ddns.net
- Backend Port: 8080 ✅ (Firewall Open)
- Frontend Port: 3000 ✅ (Firewall Open)
Services Running
- Backend: http://0.0.0.0:8080 (listening on all interfaces)
- Frontend: http://0.0.0.0:3000 (listening on all interfaces)
Quick Checklist
- Update No-IP DNS to point to 170.254.17.146
- Configure router port forwarding for port 3000
- Configure router port forwarding for port 8080
- Wait 5-15 minutes for DNS propagation
- Test from external network (phone with WiFi off)
Troubleshooting
If DNS still shows old IP
# Clear DNS cache (if on Windows)
ipconfig /flushdns
# Check what IP DNS resolves to
nslookup houseofprayer.ddns.net
# Test direct IP access
curl http://170.254.17.146:3000
If you can't access even with direct IP
- Check your ISP doesn't block ports 3000 or 8080
- Verify router port forwarding is saved and active
- Check if router needs reboot after port forwarding changes
- Some ISPs block incoming connections - may need to contact them
Check if your ISP blocks ports
# From another network/phone:
telnet 170.254.17.146 3000
telnet 170.254.17.146 8080
Alternative: Use Standard Port 80/443
If port 3000/8080 are blocked, you can:
-
Use Nginx as reverse proxy on port 80:
- http://houseofprayer.ddns.net → redirects to port 3000 internally
-
Get SSL certificate with Let's Encrypt:
- https://houseofprayer.ddns.net → secure access
