Busco a un profesional que pueda desarrollar un sistema simple de monitoreo y graficación de tráfico de red basado en un esquema que ya tengo (dibujado en Packet Tracer solo como referencia visual). Objetivo Implementar un entorno donde se pueda: Capturar el tráfico entre dos redes conectadas entre sí y a Internet. Graficar y visualizar ese tráfico (por ejemplo, usando Wireshark, Python, Grafana, o la herramienta que el desarrollador considere adecuada). Alcance mínimo Configurar dos redes básicas (cada una con un cliente y un servidor). Conectarlas por un router central que permita comunicación e Internet. Implementar un Servidor de Monitoreo que capture el tráfico de ambas redes. Generar gráficas o reportes vi...

I need an experienced network-security professional to plan and configure a new hardware firewall for our small-to-mid-size LAN. I already have the appliance on hand; what I am missing is the know-how to wire it in, build an initial ruleset, and verify that traffic is flowing only where it should. Here’s what I expect: • A brief discovery session so you understand our current topology and the appliance model (we commonly use Cisco ASA, Palo Alto, or Fortinet gear—let me know which one you specialise in). • Step-by-step configuration of interfaces, zones/VLANs, NAT, and security policies that reflect our existing subnet design. • Activation of basic threat-prevention features and logging. • Live validation—ping, traceroute, and packet captures&...

I need a Check Point firewall engineer to configure between one and three VLANs on an existing appliance so that my server traffic is properly segregated from the rest of the network. The hardware is already racked and running the latest R8x code; what’s missing is the VLAN definition, interface tagging, and any associated security policies. Scope of work • Create the required VLAN interfaces on the gateway and assign the correct IP addressing schema I will provide. • Adjust or build the security rules so that only approved inter-VLAN flows are allowed. • Verify reachability to and from the server network and document the final topology (screenshots of SmartConsole and a brief change log are fine). Acceptance criteria • All servers sit exclusively on the...

Hiring: Senior Systems Engineer — Build ISP-Level Email Filtering Prototype (Postfix, rspamd, Vault, AEAD) Remote • Contract (4–6 weeks) • Equity available We are building the first working prototype of , an ISP-level scam/spam/malware prevention system that moves message filtering away from user devices and into the provider network. A patent is filed, and now we need an expert engineer to assemble the prototype using commercial off-the-shelf components. What You Will Build A fully operational ISP-style email pipeline demonstrating: SMTP ingress (Postfix or Exim) Filtering (rspamd + ClamAV) Malicious quarantine inside ISP AEAD envelope encryption (AES-GCM or ChaCha20-Poly1305) Session key wrapping using Hashicorp Vault Provider-signed provenance headers (PV...

We need onsite engineer for one day work. The scope will be Rack and Stack of Cisco devices

I already have PacketFence installed and a Cisco 9800 wireless-LAN controller online; I just need a knowledgeable hand to finish the guest-access workflow. The scope is narrow: • Build a simple, branded guest user portal in PacketFence that pops up automatically on the 9800 WLAN. • Enable the device registration process so every new MAC is tracked. • Configure dual-step guest authentication: first e-mail verification, then a one-time-password. I have an SMTP server ready to relay the messages, so no new mail infrastructure is required. • Verify that the RADIUS flow, captive-portal redirect, and VLAN assignment work end-to-end for both 2.4 GHz and 5 GHz SSIDs. A brief walkthrough of the key screens or a small runbook will be the acceptance criteria; a short rem...

I need an experienced network engineer to help me squeeze every ounce of reliability out of our existing Local Area Network. The goal is simple but critical: improve overall performance by eliminating the small interruptions and random hiccups that erode user confidence. You will start with a brief discovery session so I can walk you through the current topology, hardware inventory (Cisco switches and a FortiGate edge), and the pain points we see on our monitoring dashboards. From there I’m expecting a clear action plan that identifies root causes and shows exactly how you’ll raise reliability—whether that means refining VLAN design, adjusting QoS policies, upgrading firmware, or fine-tuning Spanning Tree parameters. Once agreed, implement the approved changes during a ...

Title: Pull Cisco Switch Configs into Nautobot (≈30 devices) Scope: Set up automated config collection for ~30 Cisco switches (2960, 9200, and a few others) so running/startup configs appear in each device’s Config tab in Nautobot. Preferred approach (flexible): • Nautobot Golden Config + Nornir using Netmiko or NAPALM (your choice). • I typically use Ansible, but use whatever gets the best, reliable result. Requirements: • Proven Nautobot + Golden Config (or equivalent) experience • Cisco IOS/NX-OS familiarity (SSH/enable) • Can handle per-platform drivers and optional jump hosts/custom ports • Secrets management via env or HashiCorp Vault (nice to have) Deliverables: 1. Working job(s) that pull configs on demand and on schedule 2. Con...

I run a mixed fleet of Linux and Windows servers and need a seasoned administrator to take full ownership of them. The work starts with a clean, standards-based setup and configuration, then shifts into continuous care: patching, user and permission hygiene, log reviews, capacity planning, and rapid incident response. Security is a priority, so hardening, firewall rules, malware protection, and routine vulnerability checks all sit inside the remit. These machines sit across a combination of on-prem hardware and cloud instances, so comfort jumping between the two is important. I expect proactive monitoring—think Prometheus, Grafana, CloudWatch or similar—so issues surface before they become outages, along with clear, well-commented documentation I can hand to auditors or new...

Guest access on my Cisco 9800 WLC is stuck at the authentication stage. PacketFence is in place, yet users never clear the portal. I need both email-based and OTP-based workflows running smoothly, but I’m not 100 % certain the WLC side is configured correctly and the RADIUS exchanges/CoA rules line up. Here’s what I need, and fast—ideally within the next 24 hours: • Review and correct the Cisco 9800 WLAN, AAA, ACL and VLAN settings so they match PacketFence requirements. • Tidy up PacketFence guest portal, RADIUS and SMS/email gateways to support the dual-step (email + OTP) flow. • Prove it works: a test client should hit the captive portal, receive the verification email plus OTP, submit it and land on the open internet. • Hand over any comman...

There are roughly one hundred Windows workstations on my network that now need a single, well-tuned pfSense deployment at the edge. The objective is straightforward: harden the perimeter and put clear, enforceable policies around every byte leaving or entering—whether it is web browsing, email, file transfers, or broader data-sharing traffic. The appliance (physical or virtual, whichever you recommend for stability and throughput) must sit between our ISP router and the core switch, serve DHCP if required, and log everything in a way that makes later auditing painless. I also need sensible, maintainable rule sets rather than a tangle of one-off exceptions—think clean NAT, VLAN-aware segmentation, and simple queues for bandwidth management. Please plan on: • Installing a...

I need FS switches configured primarily for network segmentation. The setup will involve configuring between 1 to 5 FS switches. These switches will connect to servers and other network switches. We have a leaf and spine setup for network access and San to server access. We continue to drop connections between the SAN and server and need help troubleshooting why that is happening.
