Services:Prerequisites
Before adding a new service to the reverse proxy system, ensure you have the following:
Service Information
Subdomain name (e.g., newservice.jb-vpn.uk)
Internal IP address (usually 10.8.0.2 for Synology NAS)
Internal port number (e.g., 8080, 3000, etc.)
Protocol (HTTP or HTTPS)
DNS Configuration
DNS A record created pointing subdomain to VPS IP (87.106.61.62)
DNS propagation completed (can take up to 48 hours, usually much faster)
Verify DNS Configuration
==== Check DNS resolution ==== nslookup newservice.jb-vpn.uk == Or using dig == dig newservice.jb-vpn.uk +short
Service Verification
Before configuring the reverse proxy, verify:
Service is running on Synology NAS
Service is accessible from VPN network
Test from VPS: curl http://10.8.0.2:[PORT] ### Test Service Accessibility
== Test service from VPS == curl http://10.8.0.2:8080 == Check if service is listening (from Synology NAS or via SSH) == netstat -tlnp | grep PORT_NUMBER
System Requirements
Ensure the following are in place:
OpenVPN tunnel is active (tun0 interface up)
Synology NAS is connected to VPN (10.8.0.2 reachable)
Nginx is running on the VPS
Port 80 is accessible (required for SSL certificate validation)
Verify System Status
==== Check VPN connectivity ==== ping 10.8.0.2 == Check nginx status == systemctl status nginx == Check VPN interface == ip addr show tun0
