3. Click on rtbsoftware.org
4. Go to DNS Records
5. Delete any existing A records for @ and nextcloud

Router Configuration

Port Forwarding Requirements

Configure your router to forward the following ports to your Nextcloud server:

1. HTTP Traffic

   • External Port: 80
   • Internal Port: 80
   • Protocol: TCP
   • Internal IP: [Your Nextcloud server's local IP]

2. HTTPS Traffic

   • External Port: 443
   • Internal Port: 443
   • Protocol: TCP
   • Internal IP: [Your Nextcloud server's local IP]

Router Setup Steps

1. Access router admin panel (typically http://192.168.1.1)
2. Navigate to Port Forwarding or Virtual Server section
3. Create the port forwarding rules as specified above
4. Save and apply changes
5. May need to restart router for changes to take effect

Dynamic DNS Updates

Since you're using a dynamic IP address, you'll need to keep the DNS records updated when your IP changes.

Automatic Update Methods

1. Porkbun API Script - See scripts/update-dns.ps1
2. Manual Check Script - See scripts/check-ip.ps1

Porkbun API Setup

1. Enable API access for your domain in Porkbun
2. Generate API key and secret key
3. Store credentials securely (never commit to git)
4. Use the update script to automatically update DNS records

DNS Propagation

After making DNS changes:

1. Changes typically take 5-30 minutes to propagate
2. Use nslookup to verify DNS changes:

   nslookup rtbsoftware.org
   nslookup nextcloud.rtbsoftware.org

3. Clear local DNS cache if needed:

   ipconfig /flushdns

Security Considerations

1. Use HTTPS only (get SSL certificate via Let's Encrypt)
2. Configure firewall rules on Nextcloud server
3. Regular security updates
4. Strong passwords and 2FA
5. Regular backups
