Emin H.

I help businesses troubleshoot, secure, and improve production networks with a focus on FortiGate firewalls, MikroTik routers, UniFi networks, VPNs, VLANs, routing, firewall rules, and network monitoring. My work is focused on practical network problems such as: • Site-to-site IPsec VPN setup and troubleshooting • FortiGate firewall policies, NAT, routing, and security hardening • MikroTik routing, firewall, VPN, and RouterOS troubleshooting • UniFi VLAN, Wi-Fi, guest network, and segmentation setup • Firewall rule review and security optimization • Zabbix/SNMP monitoring and network visibility • Routing and connectivity troubleshooting for business networks I do not make random changes on production systems. I first review the topology, understand the traffic flow, check the risks, take backups where possible, and then apply controlled changes with clear documentation. I have hands-on experience with enterprise and multi-branch environments where uptime, secure access, VPN stability, monitoring, and clean firewall configuration are important. If you need help with a VPN issue, firewall configuration, MikroTik routing problem, UniFi VLAN setup, network monitoring, or security review, I can help you investigate the problem and implement a safe solution. Send me a message with your current issue, device model, topology, and goal, and I will help you choose the safest way to fix or improve it.
