4G, 5G, Starlink or hybrid. CGNAT locks most cellular and satellite connections behind a shared, non-routable address. Speedroute solves that permanently. A fixed, dedicated public IPv4 address to any UK installation over any connection type. Fixed monthly fee. Pre-configured hardware shipped zero-touch ready.
Carrier Grade NAT arrived when mobile networks ran out of IPv4 space. Every UK mobile operator, and Starlink, now hides devices behind a shared address pool. Your 4G router, your Starlink dish, your hybrid WAN — none of them have a routable public IP by default.
That means no inbound connections. No remote NVR access. No VPN termination. No payment terminal reach-back. No telemetry polling. No out-of-band management.
This is not a configuration problem. It is a structural one. The only solution is an IPv4 overlay that assigns a real, routable public address independent of what the underlying network does.
Ruggedised Teltonika hardware with WireGuard pre-loaded, multi-network eUICC SIM fitted. Plug in, power on. Nothing to configure on site.
WireGuard connects automatically to the Speedroute London hub over whatever WAN is available. 4G, 5G, Starlink or fixed broadband.
Your dedicated public IPv4 is announced via BGP. It belongs to your tunnel only. Whitelist it, host on it, reach it from anywhere in the world.
Traffic hitting your static IP routes through the hub to your device. The WAN can change, roam or fail over. Your IP does not change.
Static IPv4 matters most in sectors where remote access, telemetry and inbound connectivity are operational requirements, not optional extras.
Site offices, welfare units, gate CCTV and machinery telemetry from day one. No fibre on site for months. Speedroute ships with the router — construction IT gets the static IP for VPN and NVR access from groundworks.
Remote NVR access requires an inbound-routable IP. CGNAT blocks it. Speedroute removes the wall. One SKU, one fixed monthly fee. The monitoring centre whitelists the static IP and they are in.
Starlink delivers the bandwidth rural businesses need but arrives with CGNAT. Plug Speedroute into the Starlink LAN port. Static IP delivered. VPN, CCTV and payment systems all work. Add 4G failover.
BESS aggregators and DNP3/Modbus dispatch systems use IP-whitelisted polling. A CGNAT address is invisible to them. Speedroute provides the static, whitelistable IPv4 on hardened hardware built for plant environments.
When the primary broadband fails, the MSP needs another route in. Speedroute 4G as a secondary always-on link. Whitelist the static IP in your management platform. Every broadband failure resolved remotely.
Parcel lockers, EV charge points and vending machines need inbound IP for firmware push, diagnostics and video retrieval. CGNAT blocks all of it. Speedroute provides the missing inbound channel.
For years, Three Mobile's 3internet APN gave installers a public IP on a cellular SIM. Thousands of CCTV installs and remote access points across the UK rely on it.
The Vodafone/Three merger changes that. Network rationalisation will move 3internet into standard CGNAT. When that happens, every installation depending on 3internet for inbound access loses connectivity simultaneously.
Speedroute is network-agnostic. It works on EE, Vodafone, O2, Three or any MVNO. Multi-network eUICC SIM included. Migrate before the window closes.
Three 3internet APN — public IP assigned directly, no CGNAT. It worked. But single-carrier and always fragile.
Vodafone/Three merger approved. Integration underway. 3internet APN continuation is not guaranteed post-merger.
Hundreds of installs across the UK lose inbound connectivity when 3internet is withdrawn. CCTV, access control, telemetry — all dark simultaneously.
Network-agnostic static IPv4. Works on any UK network, any MVNO. Multi-network eUICC SIM included. No carrier lock-in.
Every Speedroute plan runs on a fixed monthly fee. No per-GB charges. Pre-configured hardware options across all tiers.

Speedroute is not a startup guessing at a connectivity problem. It is a product built by engineers who have been deploying cellular infrastructure in the field since GPRS was cutting-edge. 2G, 3G, 4G LTE, 5G NSA and SA, NB-IoT, LTE-M, LoRaWAN, Sigfox, satellite. Every generation of the technology. Every generation of the problems it creates.
We watched CGNAT arrive. We watched it become the default. We built Speedroute because the workarounds that existed — proprietary cloud relays, carrier-specific APNs, fragile L2TP tunnels — were all expensive, unreliable or single-carrier dependent.
WireGuard over a BGP-announced IPv4 block is the right architecture. Lightweight. Secure by default. Handles cellular roaming without dropping sessions. We use the same Teltonika hardware on our own infrastructure that we specify for customers.
