Enterprise Network & Security Architect (Mentor-Based) Virtual Enterprise Home Lab Design & Guided Implementation Project Overview I am an IT student in Germany building a fully virtual enterprise-style home lab for hands-on learning. This lab will simulate a small-to-mid enterprise network using virtualization technologies. The objective is not just implementation, but deep architectural understanding and guided learning. I am looking for an experienced Network & Security Engineer who can: • Design the full enterprise-style architecture • Guide me step-by-step through implementation • Explain design decisions and security reasoning • Review my configurations • Provide structured documentation templates • Conduct live knowledge-transfer sessio...

I have several Cisco-based lab and production environments that need hands-on attention from someone who already feels at home with CCNA-level work. Over the next few weeks I’ll be refining network configuration, tightening security, and—most importantly—sorting out a few stubborn routing-protocol issues that keep popping up. Here’s the situation: • Network configuration needs polishing on a mix of Catalyst switches and ISR routers, including VLAN planning, trunking, and interface tuning. • Day-to-day troubleshooting consumes far too much time; I want clear root-cause analysis when links flap, routes disappear, or access lists misbehave. • Security hardening is overdue—standard ACLs are in place, but I need smarter filtering and a quick r...

My Mikrotik-based network has started dropping connections throughout the day. Speeds are fine when the link is up, but users complain about frequent disconnections that force them to reconnect to services. I need an expert who already works comfortably with RouterOS, WinBox and basic CLI to dive in, locate the root cause and tune the configuration for consistent performance. Scope of work • Analyse current RouterOS settings (queues, bridges, firewall, wireless, CAPsMAN if present) • Isolate the trigger behind the disconnections—whether it is interface flapping, DHCP lease issues, NAT rules, routing loops, or CPU/RAM spikes • Optimise performance parameters without disrupting existing production traffic • Provide a brief hand-over note summarising the cha...

My EVE-NG lab, running inside Proxmox, suddenly stopped receiving addresses from my internal router’s DHCP pool. The VM is attached to a bridged interface and previously picked up an IP in the correct range without problems. Nothing in the network layout has changed and I have already restarted the Proxmox host, double-checked the EVE-NG adapter settings, and reviewed the router configuration, yet the bridge no longer passes DHCP traffic. And also Nexus /BigIP and others switch not coming up I want the environment back to the point where EVE-NG instances reliably obtain an IP from the router and are reachable on the LAN. Diagnosis should cover the Proxmox bridge, the underlying Linux network stack, and any EVE-NG specifics (vrf, cloud interfaces, tap devices, etc.). If the fix invo...

I need a clean, working GlobalProtect remote-access VPN on my Palo Alto Networks PA-3260. The plan is simple: • Local database authentication with standard username/password logins—no external Radius or LDAP. • Split-tunnel design so only traffic destined for our corporate subnets crosses the tunnel; all other internet traffic stays local to the user. • Two static 1:1 NAT rules for internal servers, complete with the matching security and U-Turn policies. You’ll build the portal and gateway, set the appropriate agent configurations, create the local user accounts, specify the split-tunnel include routes, and test from a Windows or macOS GlobalProtect client. Once that works, we’ll verify inbound and outbound reachability for the NATed servers. Acce...

Necesito que un especialista configure mi router Mikrotik para ofrecer acceso a internet en una red 100 % inalámbrica mediante fichas impresas. Alcance: • Crear y activar un portal Hotspot que me permita tener control total de usuarios: límites individuales de velocidad, número de dispositivos y posibilidad de deshabilitar o renovar cuentas en cualquier momento. • Diseñar la plantilla de voucher e integrar la generación automática de fichas impresas (username, contraseña, tiempo o datos, código de barras/QR si es conveniente). • Ajustar colas, perfiles y reglas de firewall para que cada ficha respete el ancho de banda asignado y evitar que los usuarios compartan la conexión. • Redactar una guía...
