Network & VPN

Remote network and VPN support

Remote technical support for private individuals who need help with network connectivity, routing, DNS, VPNs, firewalls and communication between servers, virtual machines and private networks.

This service focuses specifically on network-level problems: systems that cannot reach each other, routes that do not behave as expected, VPN tunnels that fail, DNS issues and connectivity problems between hosts or networks.

Typical issues I can help with

• Routing and gateway problems
• DNS resolution issues
• WireGuard and VPN troubleshooting
• Firewall rules blocking legitimate traffic
• Connectivity between servers and virtual machines
• Private network and subnet communication problems
• Port reachability and service connectivity issues
• Network interface and route configuration
• Remote access between separate networks

What this service does not cover

General Linux configuration problems belong under Linux Server Support. Preventive security reviews, access hardening and attack-surface reduction are handled through Security Hardening.

This service is specifically for problems whose main cause is related to networking, routing, DNS, VPNs or connectivity.

How the service works

Support is provided remotely and by appointment. Before any paid work begins, I review the network setup and confirm whether the issue falls within the scope of this service.

The selected session covers up to the purchased support time. If additional time or more extensive work is required, I will explain it clearly and continue only after your approval.

Trace the path, find the break

Network problems are often caused by one incorrect route, rule, DNS response or interface setting. I trace the communication path step by step to identify where connectivity actually fails.

This is a remote technical support service for private individuals.
