# 🌐 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)
|
|
|
|
1. **Login to No-IP**:
|
|
- Go to <https://www.noip.com/login>
|
|
- Login with your account
|
|
|
|
2. **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"
|
|
|
|
3. **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:
|
|
|
|
```bash
|
|
# 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
|
|
|
|
1. **Frontend Access**:
|
|
- External Port: 3000
|
|
- Internal IP: 192.168.10.130
|
|
- Internal Port: 3000
|
|
- Protocol: TCP
|
|
|
|
2. **Backend API**:
|
|
- External Port: 8080
|
|
- Internal IP: 192.168.10.130
|
|
- Internal Port: 8080
|
|
- Protocol: TCP
|
|
|
|
### How to Configure (General Steps)
|
|
|
|
1. Login to your router (usually <http://192.168.10.1> or <http://192.168.1.1>)
|
|
2. Find "Port Forwarding" or "Virtual Server" section
|
|
3. Add the rules above
|
|
4. 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)
|
|
|
|
```bash
|
|
curl http://localhost:3000
|
|
curl http://localhost:8080/api/songs
|
|
```
|
|
|
|
### 2. Test from Local Network
|
|
|
|
```bash
|
|
curl http://192.168.10.130:3000
|
|
curl http://192.168.10.130:8080/api/songs
|
|
```
|
|
|
|
### 3. Test DNS Resolution
|
|
|
|
```bash
|
|
nslookup houseofprayer.ddns.net
|
|
# Should show: 170.254.17.146
|
|
```
|
|
|
|
### 4. Test External Access (from phone/another network)
|
|
|
|
- <http://houseofprayer.ddns.net:3000>
|
|
- <http://houseofprayer.ddns.net:8080/api/songs>
|
|
|
|
## 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
|
|
|
|
```bash
|
|
# 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
|
|
|
|
1. Check your ISP doesn't block ports 3000 or 8080
|
|
2. Verify router port forwarding is saved and active
|
|
3. Check if router needs reboot after port forwarding changes
|
|
4. Some ISPs block incoming connections - may need to contact them
|
|
|
|
### Check if your ISP blocks ports
|
|
|
|
```bash
|
|
# 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:
|
|
|
|
1. **Use Nginx as reverse proxy on port 80**:
|
|
- <http://houseofprayer.ddns.net> → redirects to port 3000 internally
|
|
|
|
2. **Get SSL certificate with Let's Encrypt**:
|
|
- <https://houseofprayer.ddns.net> → secure access
|
|
|
|
Would you like help setting up Nginx reverse proxy?
