With 10+ years in network infrastructure and security, I help businesses resolve the issues that stop daily operations: failed VPNs, blocked firewall traffic, unstable branches, cloud connectivity and VoIP/SIP problems. My focus is simple: find the actual root cause, restore services with minimum disruption, and avoid risky trial-and-error changes on a live network. I have supported enterprise, government, data centre and multi-site business networks using Fortinet, Cisco and other leading firewall platforms, with hybrid connectivity across AWS, Microsoft Azure and Google Cloud. My "Zero-Risk" Methodology Many engineers rely on "guess and check" troubleshooting. I don't. I never make blind changes on a live production network. Before altering your setup, I map your current design, analyze your routing, and review firewall policies. I always pull backups, engineer a rollback plan, and execute controlled, fully documented changes. My goal is permanent stability, not temporary patches. Core Expertise & Outcomes Delivered: Firewall & Threat Management: FortiGate, Cisco, UniFi, and MikroTik. (Comprehensive policy audits, legacy rule cleanup, and strict hardening). Complex VPN Troubleshooting: Site-to-Site, Remote-Access, IPsec, and SSL VPNs. If your tunnel is unstable or failing, I will stabilize it. Cloud & Hybrid Infrastructure: AWS (VPC, Security Groups), Microsoft Azure (VNet, VPN Gateway, NSG), and Google Cloud. I build secure, seamless office-to-cloud and cloud-to-cloud bridges. VoIP/SIP Optimization: Resolving SIP registration failures, NAT traversal bugs, one-way audio, and call drops using precise QoS, Voice VLANs, and Cisco CUBE support. Advanced Routing & Switching: SD-WAN deployments, dual-ISP failover, VLANs, and comprehensive LAN/WAN/Wi-Fi troubleshooting. How We Can Partner: Emergency Troubleshooting: Rapid isolation and resolution of critical connectivity, routing, or security failures affecting your users. Network Health & Security Audits: Deep-dive reviews to identify vulnerabilities, clean up messy configurations, and provide actionable security roadmaps. Infrastructure Setups & Migrations: End-to-end planning for new branch offices, secure remote work environments, and physical security networks (CCTV/Biometrics). Retained Network Support: Dependable, on-demand escalation support for internal IT teams, MSPs, software companies, and business owners. My core technical experience includes: • FortiGate configuration, migration and troubleshooting • Cisco routers, switches, Firewall, Firepower, Voice Gateway and CUBE • Fortigate, Fortinet, Mikrotik, • IPsec, SSL and remote-access VPNs • Site-to-site VPN and multi-site connectivity • SD-WAN, dual-ISP failover and policy-based routing • VLANs, routing, NAT, DHCP, DNS and LAN/WAN troubleshooting • Firewall policy review, cleanup and security hardening • Wi-Fi, office connectivity and branch network support • AWS VPC, routing, security groups, VPN and hybrid access • Azure VNet, NSG, VPN Gateway, peering and hybrid connectivity • Google Cloud VPC, firewall rules, VPN and network access • SIP, NAT traversal, RTP, one-way audio and call-drop issues • Voice VLANs, QoS and firewall policies for voice traffic • Network diagrams, documentation and handover notes Where access permits, I take a backup, confirm the rollback plan, make controlled changes, test the traffic flow and document the result. This is especially important on production firewalls, remote branches, VPN tunnels and voice networks, where one quick change can affect another service. Let’s Secure Your Network Whether you need a one-time emergency fix, a comprehensive security audit, or ongoing support, I am here to help. Please share: Your primary firewall/hardware vendor and model. The exact issue or project scope (and any recent changes made). The number of sites or users affected. Once I understand your exact setup and the business impact, I will provide a clear, safe plan of action to get your network running flawlessly.
