I am a CCIE Security/NSE4/AWS, Azure and OCI Foundation certified network professional and I have worked for 6 plus years in Cisco TAC security team. I have an over all 13 plus years of experience. I have worked on multivendor products like firewalls like Palo Alto, Cisco, Fortigate, Sonicwall etc, load balancers (F5 LTM, AFM), SDN solutions, Cisco Switches like catalyst, nexus etc. I have good exposure of configuring cisco switches (Nexus and Catalyst) and routers. I have expert level knowledge of Cisco firewalls (ASA/FTD), fortigate, pfsense and palo alto. I have very strong troubleshooting skills and I have done several migrations of firewalls and other technologies. I have migrated several multi vendor firewalls to Cisco Firewalls and vice versa. Also, have worked on a mass migration project like migrated more than 70 cisco ASAs to Cisco FTDs. I am managing more than 15 Palo Alto firewalls and 30 Fortigate firewalls. I have sounds concepts and working knowledge of AWS advanced networking and Azure networking. I have configured several VPN connections between cloud and multivendor firewalls.

I have been working in network infrastructure and security for around 15 years, including enterprise, government, data center, and business network environments. My work is mainly around firewalls, VPNs, routing, switching, Wi-Fi, SD-WAN, VoIP/SIP, cloud networking, and hybrid connectivity across AWS, Microsoft Azure, and Google Cloud. Most clients contact me when something important is affecting their daily operations — VPN users cannot connect, a site-to-site tunnel is unstable, firewall rules are blocking business traffic, branch users are facing downtime, cloud servers are not reachable from the office network, or VoIP calls have issues like one-way audio, SIP registration failure, NAT problems, or call drops. I work with technologies and environments such as: • FortiGate firewall configuration and troubleshooting • Cisco routers and switches • Sophos, SonicWall, Palo Alto, pfSense and MikroTik • Site-to-site VPN and remote-access VPN • SSL VPN / IPsec VPN troubleshooting • SD-WAN and dual-ISP failover • VLAN, routing, NAT, DHCP, DNS and LAN/WAN issues • Firewall policy review, cleanup and hardening • Wi-Fi and office connectivity troubleshooting • Branch office and multi-location network support • AWS VPC, routing, security groups, VPN and cloud connectivity • Azure VNet, VPN Gateway, NSG, VNet peering and hybrid access • Google Cloud VPC, firewall rules, VPN and network access • Office-to-cloud and cloud-to-cloud network troubleshooting • VoIP/SIP troubleshooting, NAT issues, one-way audio and call drops • Cisco Voice Gateway / CUBE support • Voice VLAN, QoS and firewall rule support for voice traffic • CCTV, biometric and office device network connectivity • Network diagrams, documentation and handover notes • Ongoing remote network and security support I do not like making random changes on a live network. Before touching the setup, I prefer to understand the current design, business impact, device models, ISP links, routing, VPN design, firewall policies, cloud environment, recent changes, and the exact issue users are facing. Wherever possible, I take a backup first, plan the rollback, make controlled changes, test properly, and then document what was done. This helps avoid the common situation where one quick fix creates another problem. Typical work I can support: Firewall and VPN troubleshooting If users cannot connect, VPN is unstable, site-to-site traffic is failing, cloud access is not working, or firewall policies are blocking traffic, I can help find the root cause and fix it carefully. Network and firewall health checks I can review firewall rules, VPN objects, NAT policies, exposed services, admin access, backup status, logging, routing, and basic security risks. The goal is to give you clear findings and practical recommendations. Cloud network and hybrid connectivity I can help with AWS, Azure, and Google Cloud network access, including VPC/VNet routing, security groups, firewall rules, VPN connectivity, and office-to-cloud access issues. VoIP/SIP troubleshooting I can help with SIP registration issues, one-way audio, NAT traversal, call drops, firewall rules, voice VLANs, QoS checks, and network-related call quality problems. New office or branch network setup I can help plan and configure routers, firewalls, switches, Wi-Fi, VLANs, VPNs, internet failover, CCTV networks, biometric connectivity, and secure cloud access. Firewall policy cleanup and hardening Many firewalls become messy over time because rules keep getting added without proper review. I can help clean old rules, remove unused objects, tighten access, organize policies, and document the changes safely. Ongoing network support For businesses that need regular network help but do not want to hire a full-time network engineer, I can provide remote support for firewall, VPN, routing, switching, Wi-Fi, cloud connectivity, branch access, and VoIP/SIP issues under a clear scope. What you can expect from me: • Clear questions before I start • No unnecessary changes in production • Backup and rollback-aware work where access allows • Proper testing after configuration changes • Simple updates during troubleshooting • Clean notes after the work is completed • Honest feedback if the issue is related to ISP, hardware, licensing, cloud provider limits, or another third-party dependency I work well with business owners, IT managers, MSPs, software companies, internal IT teams, CCTV/biometric vendors, and operations teams that need dependable network and security support for one-time issues, audits, setup, or ongoing work. To start, please share: • Firewall/vendor and model • Number of sites or branches • Number of users affected • ISP links and connection type • Cloud platform, if involved • VPN or VoIP/SIP details, if applicable • A short description of the issue • Any recent change before the issue started • Whether you need a one-time fix, audit, setup, or ongoing support Once I understand the setup, I will suggest the safest next
