MikroTik RB4011iGS+RM

10-Port Gigabit Router with 10G SFP+ and Quad-Core CPU for Enterprise Networking

The MikroTik RB4011iGS+RM is a high-performance, rack-mountable router built for small-to-medium enterprise networks, ISPs, and demanding home labs that need serious routing horsepower alongside a full complement of Gigabit ports and a 10G fiber uplink. With a quad-core CPU, ten Gigabit Ethernet ports, a 10G SFP+ cage, and hardware-accelerated IPsec, it's positioned as one of MikroTik's flagship fanless routers for wired, high-throughput environments.

Overview

At the heart of the RB4011iGS+RM is an Annapurna Labs AL21400 quad-core ARM Cortex-A15 processor with auto-scaling clock speed from 533 MHz up to 1.9 GHz, paired with 1 GB of RAM and 512 MB of NAND storage. This is a substantial step up in processing power from MikroTik's smaller RouterBOARD and home-lab units, giving it the headroom to handle heavy firewall rule sets, VPN tunnels, and routing tables without breaking a sweat. It ships with RouterOS v7 pre-installed and includes a RouterOS Level 5 license, with free RouterOS updates for the life of the device (a minimum of five years).

Ports and Connectivity

The router provides ten Gigabit Ethernet ports (10/100/1000) plus one 10G SFP+ cage that also accepts standard 1G SFP modules for flexibility. The ten Ethernet ports are arranged as two independent groups of five, each connected through its own switch chip, which is worth noting when planning inter-port switching performance versus routed throughput between groups. Console access is available through an RJ45 serial port (115200 bps by default), and the RouterBOOT reset button supports multiple functions — configuration reset, full reset, or Netinstall mode — depending on how long it's held during power-up. Unlike some of MikroTik's other RB and L009 series devices, this model does not include a USB port.

Power Options and PoE

The RB4011iGS+RM accepts power two ways: a DC jack (12–57V) or passive PoE-in (18–57V), and it ships with a 24V/1.5A power adapter in the box. Ether10 doubles as a passive PoE-out port, supplying up to 600 mA at low voltage or 420 mA at high voltage for a downstream device such as an access point. Maximum power consumption is rated at 33W under full load, or as low as 18W without attached PoE devices, and the entire unit is passively cooled — no fans, no moving parts.

Hardware-Accelerated Security

A standout feature of the RB4011iGS+RM is its onboard IPsec hardware acceleration, which offloads encryption and decryption from the CPU. This lets the router maintain strong VPN throughput even with IPsec tunnels active, making it well suited for site-to-site VPNs and secure remote access without the performance penalty typically associated with software-based encryption.

Build and Physical Design

The router measures 228 x 120 x 30 mm and ships with 1U rackmount ears already attached, so it's ready to install in a standard server rack out of the box without needing separate accessories. It's rated for a wide operating temperature range of -40°C to 70°C, has an estimated MTBF of around 200,000 hours at 25°C, and includes onboard PCB temperature and voltage sensors for hardware health monitoring. It carries CE, EAC, and RoHS certification.

Software: RouterOS v7

Running RouterOS v7 with a Level 5 license, the RB4011iGS+RM supports the full range of MikroTik's enterprise networking features: advanced firewalling and NAT, VLANs, hardware-accelerated IPsec alongside WireGuard and OpenVPN, dynamic and static routing (OSPF, BGP, RIP), traffic shaping and queueing, hotspot and captive portal management, bonding/link aggregation, and container support, all configurable through WinBox, WebFig, or the command-line interface.

Typical Use Cases

The RB4011iGS+RM is well suited to small and medium business networks that need a capable router/firewall with enough Gigabit ports to avoid a separate switch, ISPs and WISPs looking for an affordable edge or customer-premises router with a 10G uplink, and site-to-site VPN deployments that benefit from hardware-accelerated IPsec. It's also a popular choice for advanced home labs and RouterOS enthusiasts who want significantly more CPU headroom and port density than entry-level or home-lab-focused models like the RB5009 or L009 series.

Note: As with all MikroTik devices, the RB4011iGS+RM runs RouterOS, which offers extensive configurability but has a steeper learning curve than typical consumer routers. Its higher CPU performance and hardware IPsec acceleration make it particularly well suited to VPN-heavy or business-grade deployments compared to MikroTik's smaller home-lab routers.
