My 5G home connection is delivered through an Archer NX200 5G router and, like many 5G plans, it sits behind CGNAT. Because of this, I cannot reach my internal network from the outside world. The goal is clear: Remote Access. I need to log in reliably to my Computers, Smart Home Devices and Security Cameras, as well as a small PBX and a Draytek firewall. Dynamic DNS is already running with NOIP, yet CGNAT keeps every incoming request from ever reaching the LAN. What I’m looking for is a practical, reproducible way around that limitation: • A working solution that lets me initiate inbound connections (HTTPS, SSH, VoIP, etc.) from anywhere. • Detailed, step-by-step configuration on the Archer NX200 5G and any additional hardware, tunnel, or cloud service you recomme...

I have an STC 5G connection running on a TP-Link Archer NX200 router. The connection is behind CGNAT, meaning I do not have a real public IP. I am looking for an expert to provide a solution to get a Dedicated Static Public IP so I can remotely access my internal network (Router management, SIP devices, etc.) using my noip DDNS Conditions: I cannot upgrade to a Business SIM card. I do not want to run a local PC 24/7 as a bridge. I just need a working Static IP solution that routes traffic from the outside directly into my local network. Please propose your method and how we can implement i

I need a technician who can take this job from bare walls to a fully operational surveillance system. The work starts with assembling and securing a tidy, service-friendly rack, then running and labeling all network cables—indoors through ceilings and walls, outdoors through weather-proof conduit—so every drop ends cleanly in the rack and at each camera mount. All cameras are IP units and must be mounted both inside and outside the building. They have to operate with night vision, motion detection and true high-definition footage, so lens alignment, focus and network bandwidth should be verified on site. Once physically installed, each camera should be patched into the switch (PoE where possible), added to the NVR or VMS, and tested for live view and recording. Deliverables...

I need hands-on help at our site to get a new network rack fully operational and to cover some light end-user support while we go live.
