Learning objectives

  • Master advanced TCP/IP mechanisms for a professionally certifying training
  • Configure optimized IP routing in business environments
  • Deploy secure VPNs based on TCP/IP protocols
  • Implement firewalls to protect critical network flows
  • Develop TCP/IP troubleshooting skills to reduce downtime
  • Optimize network performance and acquire professional skills

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Program

Module 1TCP/IP Fundamentals: IP, ICMP, ARP Protocols (Wireshark, Network Simulations)

Discover advanced IP layers with Wireshark to analyze packets in real-time, configure static and dynamic IP addresses via DHCP, perform practical exercises on ARP and ICMP to diagnose network conflicts, apply these concepts to real business cases, produce an initial traffic analysis report as a concrete deliverable from this immersive day.

Module 2TCP/IP Routing: RIP, OSPF, BGP Protocols (Cisco Packet Tracer, GNS3)

Dive into dynamic routing with Packet Tracer and GNS3, configure OSPF routing tables for multi-site topologies, simulate BGP scenarios for WAN interconnections, test network convergence under load, analyze logs to optimize paths, generate routing diagrams as deliverables, apply directly to real business infrastructures.

Module 3In-Depth TCP: Flow Control, Congestion (Tcpdump, iperf)

Explore TCP mechanisms with Tcpdump to capture handshakes and ACKs, measure performance via iperf simulating congestions, adjust receive windows to boost throughput, diagnose packet losses in practical labs, integrate IPv6 for smooth transitions, produce a network performance benchmark as a key deliverable for your professional expertise.

Module 4TCP/IP VPN: IPsec, OpenVPN (StrongSwan, Dedicated Servers)

Deploy IPsec VPN tunnels with StrongSwan on Linux, configure OpenVPN for secure remote access, test authentication via certificates and pre-shared keys, simulate MITM attacks to validate robustness, integrate NAT-T to traverse firewalls, generate ready-to-use configurations as deliverables, apply to nomadic and hybrid business cases.

Module 5TCP/IP Firewall: Stateful Rules, NAT (iptables, pfSense)

Master iptables and pfSense to filter TCP/IP flows, implement advanced stateful rules and NAT, block SYN flood scans in real-time, analyze logs with ELK for intrusion detection, optimize performance under high load, produce a firewall security plan as the final deliverable, prepare your business for current network threats through these practical exercises.

Evaluation method

  • Daily technical quizzes on TCP/IP protocols
  • Practical case studies in pairs on troubleshooting
  • Final project: simulated VPN/Firewall deployment evaluated

Learning method

  • Interactive courses with live demos on Cisco/pfSense equipment
  • Hands-on practical work in small groups of max 10
  • Real case studies from impacted French companies
  • Advanced Wireshark/GNS3 simulations for complex scenarios

Methods, materials and delivery

The Training TCP/IP - Mastering Protocols for Secure Networks program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training TCP/IP - Mastering Protocols for Secure Networks program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Training TCP/IP - Mastering Protocols for Secure Networks program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Learni programs are available inter-company and intra-company, onsite or remote. Enrollments are possible up to 48 business hours before the program starts. Our programs are eligible for corporate funding paths. Contact us to discuss your training project and funding options.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
