# Port forwarding on LTE and 5G internet usually fails because of CGNAT


Cellular internet is great for fast deployment and backup connectivity, but most LTE and 5G connections do not give you a usable public IPv4 address. NeedPorts gives your machine a stable public endpoint and dedicated forwarded ports as long as it can make outbound internet connections.

## Why router port forwarding often does not work on LTE or 5G


Many cellular providers put customers behind carrier-grade NAT. Your router or hotspot may let you create a port-forwarding rule, but the public internet still cannot route inbound traffic directly to your device because the provider is sharing public IPv4 addresses upstream.


### What works locally


SSH, dashboards, game servers, cameras, APIs, or Home Assistant may work on the LAN or through the router.


### What fails publicly


Remote users hit timeouts because the LTE/5G provider does not route unsolicited inbound traffic to your connection.


## How NeedPorts helps


- The target machine opens an outbound tunnel to NeedPorts infrastructure.
- NeedPorts gives you a stable public endpoint and a reserved range of forwarded ports.
- Remote users connect to the public NeedPorts endpoint instead of trying to reach the cellular WAN IP directly.
- The client reconnects automatically when the cellular modem, hotspot, or router changes IPs.


## Good LTE/5G use cases


- temporary sites, trailers, sheds, RVs, or remote equipment with cellular internet
- backup WAN connections that take over when cable or fiber fails
- home labs or small offices using fixed wireless access
- remote cameras, dashboards, SSH, APIs, and self-hosted services that need public inbound reachability


## What NeedPorts does not replace


NeedPorts does not provide the LTE/5G service itself, fix a dead modem, or configure your router failover policy. It solves the inbound reachability problem after your machine has outbound internet access over the cellular connection.


## Plans start small


NeedPorts plans start at **$5/month** or **$30/year** for 25 dedicated ports. That is enough for many remote-access, self-hosting, and backup-connection use cases, with larger plans available when you need more services exposed or more throughput.
