• Complex routing, VLANs, VPN tunnelling, and firewall rules — all handled without performance degradation thanks to the ARM quad-core architecture and 1GB of RAM
• Deep packet inspection, complex firewall rule chains, and simultaneous multi-function operation with headroom to spare

1GB RAM — Memory for Every Workload You Can Design

The 1GB of RAM serves as a sturdy foundation, ensuring not only high-speed data processing but also overall system reliability — providing the working memory headroom to maintain large routing tables, track thousands of active firewall connections, sustain multiple concurrent VPN sessions, run hotspot gateway services, and execute complex RouterOS scripting workflows simultaneously, without ever approaching a memory ceiling.

🔌 10× Full Gigabit Ethernet Ports — Maximum Wired Density

Every Port. Full Speed. Zero Compromise.

The RB4011iGS+RM ships with ten 10/100/1000 Gigabit Ethernet RJ-45 ports — every single one operating at full 1Gbps capacity. This port density makes it the routing backbone capable of connecting:

• Multiple ISP uplinks for redundant multi-WAN load balancing and failover
• Core switches serving dozens of downstream devices
• Individual servers, NAS units, and high-throughput workstations at full wire speed
• VoIP gateways, IP cameras, and PoE-powered network devices
• Dedicated management interfaces completely isolated from production traffic

No port sharing. No speed degradation. No compromise — just ten independent Gigabit connections ready to carry your most demanding traffic loads simultaneously.

PoE Output on Port 10 — Power Your Infrastructure Over Ethernet

The device provides passive PoE-out on Ether10, supporting up to 57V with a maximum output of 600mA when powered with an 18–30V input — enabling the RB4011iGS+RM to power downstream MikroTik access points, IP cameras, VoIP phones, and other PoE-capable devices directly from the router port. Eliminate the need for a separate PoE injector on your last-hop device and keep your rack cleaner, simpler, and more efficient.

The device’s support for multiple power methods, including AC/DC adapter (12–57V DC) and 18–57V passive PoE-in, enhances its versatility significantly — adapting to various power conditions and installation environments, making it suitable for a wide range of network setups.

Power the RB4011iGS+RM over the Ethernet cable in locations where a DC outlet isn’t conveniently accessible — ideal for ceiling-mounted or remote rack deployments where cable runs are already in place.

⚡ 10Gbps SFP+ Port — The Multi-Gigabit Uplink That Changes Everything

Because Your Core Network Deserves More Than Gigabit

The RB4011iGS+RM’s 10G SFP+ port delivers unparalleled advantages, offering fast data transmission speeds that outperform traditional connections — effortlessly handling large data volumes, high-resolution multimedia streaming, and latency-sensitive applications. This means quicker backups, smoother video conferencing, and virtually lag-free online experiences.

The 10Gbps SFP+ cage is the performance multiplier that makes the RB4011iGS+RM future-proof for today’s network demands. Real-world applications of the 10G uplink include:

• 10G uplink to core switches — aggregate all ten Gigabit ports into a single 10G backbone connection without bandwidth bottlenecks

• Point-to-point links — create 10G backhaul connections between buildings or network segments

Compatible with a wide range of MikroTik-tested SFP+ modules, direct attach cables, and third-party transceivers — giving you the flexibility to build the exact fibre architecture your network demands. Note: Passive DAC modules (S+DA0001/S+DA0003) are not supported.

🔒 IPsec Hardware Acceleration — 2Gbps+ VPN Without Touching the CPU

Enterprise VPN Throughput at a Fraction of Enterprise Cost

VPN performance is where most routers reveal their true limitations. Software-based IPsec encryption consumes CPU cycles greedily — often crippling throughput on underpowered devices to just a fraction of their routing capability. The RB4011iGS+RM eliminates this problem entirely.

Benchmarks show maximum throughputs of up to 9.8Gbps for routing and bridging and over 2Gbps for IPsec VPN tunnels — delivered through dedicated hardware acceleration that handles cryptographic operations independently from the main CPU cores. The result is:

• IPsec site-to-site tunnels operating at 2Gbps+ without CPU saturation
• Multiple concurrent VPN connections sustained simultaneously without performance degradation
• AES-128 and AES-256 hardware encryption — full security without the throughput penalty of software implementation
• VPN gateway for hundreds of remote users without breaking a sweat
• Zero performance impact on other routing tasks — firewall, NAT, QoS, and routing continue unaffected during peak VPN load

This hardware-accelerated IPsec capability alone justifies the RB4011iGS+RM for any organization running remote access VPNs, site-to-site connectivity, or encrypted inter-office communication at scale.
