Thomas Dutour

Network administrator with operational experience in a critical datacenter environment.

My expertise covers the entire network lifecycle: deployment, configuration, troubleshooting, and operational maintenance on Fortinet (VDOMs included) and Cisco environments in production. I handle complex network issues — SD-WAN, IPSec/SSL VPN, routing, VLANs, NAT, ZTNA, ADVPN server publishing, MTU/TCP clamping optimization — as well as security aspects: FortiWeb WAF, dynamic ACLs via vCenter/tag integration, certificate management.

Capable of diagnosing complex production incidents, particularly IKEv2 negotiation issues (PFS mismatch, Diffie-Hellman, unstable child_SA) or IKEv1/IKEv2 migrations on Cisco ASA and FortiGate environments.

Before my current role, I spent 2 years in a work-study program in multi-client outsourcing, covering system administration, Active Directory and Exchange migrations, software installation, O365 management, Synology NAS management, and more.

Available for full remote work or on-site in Lot-et-Garonne as needed. (Within 4 weeks)
