Boosted performmance : Seamless access to cloud services
Despite its compact half-rack form factor, the RTX840 supports up to 150,000 NAT and dynamic filter sessions, delivering significantly enhanced TCP connection processing performance.
This ensures a stable and reliable network environment even when session demand temporarily spikes—such as during heavy access to cloud services in schools, offices, or other high-traffic environments.
- Throughput : Max 2.0Gbps
- IPsec Throughput : Max 1.0Gbps
- NAT Sessions : Up to 150,000
- VPN Concurrent Sessions : Up to 20 sessions
Simple, secure local breakout for major cloud platforms
Avoid Bandwidth Congestion at the Central Router
As the use of cloud services continues to grow, traffic routed from branch offices through the central network is increasing, raising the risk of bandwidth bottlenecks and service disruptions.
To address this, demand is rapidly rising for local breakout—a method that allows branch routers to connect directly to the internet without passing through the central router.
The RTX840 natively supports local breakout through destination lists defined by IP addresses or FQDNs, helping reduce the load on central routers and optimize overall network performance.
Maintenance-Free Operation
The latest destination lists used by major cloud services—such as Microsoft 365, Google services, and Windows Update—are automatically delivered from Yamaha-managed servers at no additional cost.
This enables continuous updates without requiring any changes to the initial configuration, ensuring that your local breakout rules remain accurate and up to date.
Users can also define and automatically manage their own custom service destinations.
This feature significantly reduces operational workload while maintaining a stable and efficient branch network environment.

JC-STAR Level 1 certified for trusted security compliance
The RTX840 complies with Level 1 of the JC-STAR Security Requirements Assessment and Labeling Program, established by Japan’s Information-technology Promotion Agency (IPA).
This certification makes it easier for enterprises and public institutions to select the RTX840 as a product that meets their security requirements, thereby reducing the time needed for evaluation and procurement.
In addition, its highly secure design helps minimize long-term security risks throughout the product lifecycle.
