# Competitive Security, Edge Config & Continuity Source: https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity The Edge Layer is where your private network meets the public internet. This series covers CGNAT and Strict NAT resolution, Static vs. Dynamic IP strategy, firewall hardening without breaking Open NAT, safe port forwarding vs. DMZ risks, DDoS protection in P2P games, DNS selection (Cloudflare vs. Google), GPN routing optimization, WPA3 wireless security, Mini-UPS power continuity for ONT+Router, and post-loadshedding reconnect storm diagnosis. Long-form article: https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/article ## Identity & Addressing - [CGNAT Explained for SA Fibre: Why You Have Strict NAT](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/cgnat-strict-nat): Understanding Carrier-Grade NAT (CGNAT) on South African fibre packages. Covers why hundreds of households sharing a single public IP causes NAT Type 3/Strict NAT, matchmaking issues, and how to request a dedicated IP. - [Static IP vs. Dynamic IP: Is There a Gaming Advantage?](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/static-vs-dynamic-ip): Comparing Static and Dynamic IP addresses for gaming. Why Dynamic IPs are superior for security (moving target), when Static IPs are essential (hosting game servers), and cost-benefit analysis for SA gamers. - [MAC Address Cloning: When and Why It's Used](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/mac-address-cloning): How MAC address locking on Vumatel/Frogfoot prevents router upgrades. Covers cloning your old router's hardware ID to bypass ISP authentication delays when swapping networking equipment. ## Edge Security - [Firewall Settings for Gamers: Balancing Security and Open NAT](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/firewall-settings-open-nat): Configuring Stateful Packet Inspection (SPI) firewalls for gaming. Why over-aggressive firewalls misidentify 128-tick game packets as UDP floods, and rule hygiene for maintaining Open NAT without compromising security. - [Safe Port Forwarding: Opening Ports Without Exposing Your Network](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/safe-port-forwarding): Manual port forwarding methodology for achieving Open NAT. Why DMZ is dangerous (removes firewall protection), which specific ports to forward per game title, and surgical port mapping best practices. - [UPnP Vulnerabilities: Should Gamers Disable Universal Plug and Play?](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/upnp-vulnerabilities): Security risks of UPnP (Universal Plug and Play) for automatic port forwarding. Covers malware exploitation vectors, convenience vs. security trade-offs, and when to disable UPnP in favor of manual configuration. - [DDoS Attacks in Competitive Gaming: Fact vs. Fiction](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/ddos-attacks-gaming): Understanding targeted DDoS attacks in high-stakes competitive play. Distinguishing volumetric attacks from lag, how attackers obtain IPs in P2P lobbies, and mitigation strategies for South African gamers. - [IP Grabbers in P2P Games: Protecting Your Home Network](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/ip-grabbers-p2p): How IP grabbers work in Peer-to-Peer game lobbies and the risks of IP exposure. Covers P2P vs. dedicated server architecture, VPN protection strategies, and preventing targeted attacks. ## Routing & Resolution - [1.1.1.1 vs. 8.8.8.8 vs. ISP DNS: The Best DNS for SA Gamers](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/best-dns-sa-gamers): Comparing Cloudflare (1.1.1.1), Google (8.8.8.8), and ISP DNS for gaming. Why DNS doesn't lower in-game ping but improves launcher/browser speed, and optimal DNS selection for South African networks. - [Gaming VPNs (ExitLag, WTFast): Do They Lower SA to EU Ping?](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/gaming-vpns-ping): Evaluating Gamers Private Networks (GPNs) like ExitLag and WTFast. How multi-path routing across undersea cables (Equiano/WACS) can stabilize jitter to Europe, and realistic ping reduction expectations for SA gamers. ## Wireless Security - [Securing Your WiFi from Neighbours: WPA3 and Disabling WPS](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/wifi-security-wpa3-wps): Essential WiFi security for dense SA estates and townhouse complexes. Why WPA3 prevents offline dictionary attacks, the WPS backdoor vulnerability, and protecting your network from unauthorized neighbor access. ## Power Continuity - [Mini-UPS Dimensioning for Load Reduction: Keeping the ONT Alive](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/mini-ups-dimensioning): Calculating Mini-UPS capacity for ONT and router backup during load reduction. Covers Voltage/Amperage requirements, DC-to-DC solutions, and keeping gaming sessions active through 2-hour power blocks. - [Clean Power vs. Modified Sine Wave: Does it Affect Router Lifespan?](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/clean-power-router-lifespan): Power quality impact on networking equipment longevity. Why Modified Sine Wave inverters cause premature router failure and intermittent resets, and the case for Pure Sine Wave or DC-to-DC backup solutions. - [Post-Loadshedding Reconnect Storms: The 10-Minute Auth Delay](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/reconnect-storm-delay): Why internet takes 10+ minutes to restore after power returns. Understanding the Reconnect Storm phenomenon where thousands of routers overwhelm ISP RADIUS authentication servers simultaneously. ## Diagnostics & Maintenance - [Router Logs & Intrusion Detection: Reading the Matrix](https://urbanx.co.za/knowledge-hub/competitive-security-edge-config-continuity/router-logs-diagnostics): Interpreting router system logs for fault diagnosis. Covers LCP termination events, blocked intrusion attempts, authentication failures, and using logs as the source of truth for network troubleshooting.
