4G LTE Router CGNAT Troubleshooting

Fix CGNAT on 4G LTE Router

Job Description

I am using an InHand IR302 4G LTE industrial router. My mobile provider uses CGNAT (Carrier-Grade NAT), which blocks me from setting up normal port forwarding to access devices remotely.

I am looking for an expert who can help me solve this problem. Possible solutions include:

Setting up a VPN tunnel (OpenVPN, IPSec, WireGuard, etc.) from my router to a server with a public IP.

Using a reverse port forwarding tool like portmap.io, ngrok, or similar tunneling services to bypass CGNAT.

Any other reliable method to allow me to remotely access devices/services on my LAN behind the IR302.

Requirements

Experience with VPNs, tunneling, and NAT traversal.

Familiarity with CGNAT limitations and workarounds.

Experience with InHand routers (IR302).



---

Deliverables

Fully working setup that allows me to access my LAN devices remotely, even under CGNAT.

Step-by-step documentation so I can repeat/manage the solution later.
