The Challenge
A leading Irish television production company faced critical connectivity issues that threatened their ability to deliver broadcast-quality content. Their setup involved sophisticated LiveU server technology for receiving video transmissions from remote LiveU client devices, but they were being blocked by Carrier-Grade Network Address Translation (CGNAT) limitations.
Technical Requirements
- Primary Connection: Starlink satellite internet requiring port forwarding capabilities
- Secondary Connection: Peplink 5G bonding unit also affected by CGNAT restrictions
- Application: LiveU server system for professional video transmission reception
- Requirement: Ability to forward specific ports essential for receiving high-quality video streams
“Our application involves the use of a LiveU server to receive video transmissions from LiveU client devices via Starlink. To receive the video transmissions certain ports need to be forwarded but CGNAT prevents port forwarding. We also use a Peplink 5G bonding unit and have the same issue with CGNAT and port forwarding.”
The client had exhausted multiple workaround attempts without success, making this a mission-critical issue for their broadcast operations.
The Solution
Recommended Configuration
- Hardware: SimRush Controller AX3
- Service: Fixed IP Address with Easy IP Hardware (12-month subscription)
- Setup: Dual WAN configuration to accommodate both Starlink and 5G connections
- Pre-configuration: Device configured by SimRush technical team before shipping
Why This Solution Worked
The Easy IP solution effectively bypassed CGNAT limitations by providing a dedicated static IP address for Starlink and advanced routing capabilities. The dual WAN setup ensured redundancy and optimal performance across both connection types.
Technical Consultation Process
SimRush provided comprehensive technical consultation to ensure compatibility with the client’s LiveU server requirements, demonstrating the company’s commitment to understanding specialized broadcasting equipment and workflows.

Business Outcomes
- Operational Excellence: Enabled continued production of broadcast-quality television programmes
- Reliability: Solution performed so well that client immediately requested a backup system
- Industry Recognition: Maintained position as one of Ireland’s most successful television production companies
- Scalability: Client confidence led to immediate expansion order
Client Satisfaction
The success was so significant that the client immediately placed a second order: “We’d like to order a second device with the identical configuration as a backup. Can you arrange this for me, please?”
