Monitorización de Redes Jobs

Mi principal necesidad es fortalecer la seguridad de mi conexión a internet. Busco a alguien que revise la infraestructura actual, identifique vulnerabilidades y realice los ajustes necesarios para proteger todos los equipos conectados. Lo que espero: • Diagnóstico inicial del estado de la red, dispositivos y contraseñas. • Configuración o reconfiguración de router, firewall y cualquier punto de acceso Wi-Fi para blindar la red. • Implementación de buenas prácticas: cifrado WPA3 (si el hardware lo permite), segmentación de redes invitadas, actualizaciones de firmware y políticas de acceso. • Pruebas de penetración básicas que confirmen la nueva solidez de la seguridad. • Informe f...

I have a MikroTik 5009B that needs to leave our lab ready for long-term production use under our brand. The job covers every layer of configuration—network setup, routing, security hardening, firewall rules, and wireless optimisation—so the unit ships with best-practice performance and rock-solid protection. Alongside the technical build I also want it re-branded: a custom RouterOS build that shows our logo on boot, a web interface reskinned in our colours, and a repeatable set of configuration scripts that already include our company name, contact banner, and standard VLAN/DHCP scheme. I should be able to flash a new device in minutes and have it come up with the same look, feel, and settings you create here. Deliverables • Complete live configuration on the 5009B, fu...

My office network has become painfully sluggish and I need a specialist to jump in, trace the bottleneck and restore normal speeds. This is a pure troubleshooting engagement—no fresh installs or routine maintenance—so I’m expecting systematic diagnostics, clear root-cause identification and a fix that holds. The issue: noticeable performance degradation that shows up as slow internet speed for all users. Basic resets and router reboots have not helped, so I suspect something deeper (mis-configured switch, bandwidth hog, firmware bug, or similar). Here’s what I need from you: • Remote or on-site diagnostics using your preferred tools (Wireshark, NetFlow analyzers, SNMP monitoring, etc.) • Actionable remediation—configuration tweaks, hardware recom...

Network Engineer for Secure Proxy & Gateway Architecture Seeking an experienced network engineer to build and deploy a secure proxy system using 3X-UI (MHSanaei) on a remote server and sing-box on a Raspberry Pi client gateway, featuring automatic protocol failover between VLESS-Reality and Hysteria2. Tech Stack Server: 3X-UI (MHSanaei fork) Client: sing-box on Raspberry Pi Protocols: Hysteria2, VLESS-Reality Project Phases 1. Proof of Concept: Set up development client environment, configure remote nodes, and deploy sing-box locally to verify routing and failover. 2. QA Deployment: Deploy a single QA server and connect the Raspberry Pi gateway for real-world testing. 3. Production Deployment: Scale to multiple production server nodes and configure the Raspberry Pi gateways for hig...

I need a ASA specialist to jump on a screen-share with me and tidy up two Cisco ASA 5512 units that are managed through ASDM. The primary goal is to enhance security, so every change we make should follow best-practice hardening guidelines. Here’s what I would like accomplished during the session: • Audit all existing Access Rules, NAT rules and Service-Policies, then rename, regroup logically and remove anything redundant or obsolete. • Confirm that the two appliances are operating correctly in active–standby high-availability mode. • Re-segment traffic so Internal, DMZ and Guest zones are clearly defined with the appropriate security levels and inter-zone policies. • Review the remainder of the configuration, highlight weak spots and suggest improv...

Preciso de suporte especializado em redes de computadores para planejar e implantar uma nova rede sem fio (Wi-Fi) em minhas instalações. O escopo inclui: • Levantamento do ambiente: análise do espaço físico, identificação de possíveis fontes de interferência e definição dos pontos de acesso ideais. • Projeto de cobertura: dimensionamento da capacidade, escolha de controladoras e access points compatíveis com as necessidades de tráfego e segurança. • Configuração e testes: instalação do equipamento, ajustes de canais, potências e SSIDs, além de testes de throughput e roaming para garantir desempenho consistente. • Seguranç...

NNF (CTCL) application in C#. Our Gateway Router login on the CM/FO test market is being rejected the TLS handshake completes, but the connection is closed immediately without any response. Looking for someone with hands-on NSE NNF certification experience who can review our setup and advise on what we are missing.

I need help completing my Network+ cybersecurity projects due next Friday. Ideal Skills and Experience: - Proficiency in network setup and configuration - Expertise in security analysis and testing - Strong documentation and reporting skills Please ensure timely completion and quality work.

I’m running a Fortigate 400E on firmware v7.2.12 (Build 1761). An IPsec tunnel is already in place for Android handsets and is performing flawlessly, but our iPhone users still can’t connect. I’d like you to create the corresponding IPsec profile, test it on current iOS versions and provide concise deployment instructions for end-users. I don’t have special demands on cipher suites or authentication beyond Fortinet’s defaults, yet I’m open to your best-practice advice. Likewise, I’m undecided about split-tunnelling: please explain the pros and cons in our environment and apply the option you recommend. Once connected, users should enjoy full access to the internal network exactly as our Android profile allows. Deliverables • Fortigate CLI ...

My small business runs entirely through a MikroTik-based network, and over the past few days something has gone wrong. Connections drop at random and performance is far from normal. I have ruled out the ISP, so the problem appears to be somewhere in the current router or switch configuration. You’ll receive full remote access to the MikroTik router and, if necessary, winbox/terminal credentials for the rest of the network gear. The task focuses purely on troubleshooting: pin-point the fault, correct it, and make sure the fix survives a reboot. If during the process you identify mis-configured firewall rules or routing loops, feel free to tidy them up, but the priority is to get the network reliably online again. Deliverables • Diagnosis summary outlining root cause • ...
