RB4011 Performance Review

Performance is one of the strongest reasons to consider the RB4011.

The router uses a quad-core AL21400 ARM processor, giving it significantly more capability than entry-level MikroTik devices.

This makes it suitable for workloads such as:

• PPPoE

• firewall filtering

• VLAN routing

• bandwidth queues

• VPN

• hotspot services

• NAT

• multi-WAN

• traffic management

• routing protocols

For many small and medium-sized professional networks, the RB4011 provides enough processing headroom to run several RouterOS services at the same time.

That is particularly important for ISPs and businesses where the router is doing much more than simply sharing an internet connection.

Ten Gigabit Ethernet Ports Review

The ten Gigabit Ethernet ports are a major practical advantage.

Many routers in this performance range provide fewer physical interfaces, forcing administrators to depend on external switches earlier.

With ten Ethernet ports, the RB4011 can directly connect several network segments.

For example:

• WAN

• Office LAN

• CCTV

• Servers

• Access Points

• Management

• Backup WAN

• VoIP

• Guest Network

• PoE device

This makes the router especially useful for network technicians who want flexibility when designing installations.

10G SFP+ Review

The RB4011 includes one 10 Gigabit SFP+ interface.

This is one of the features that separates it from many lower-priced MikroTik routers.

The SFP+ interface can be used for:

• fibre uplinks

• managed switches

• ISP backbone connections

• server networks

• high-speed LAN aggregation

For networks that are currently Gigabit but may move toward faster backbone connectivity, the SFP+ interface provides useful upgrade potential.

RouterOS Review

RouterOS is one of the biggest reasons to buy the RB4011.

The router runs RouterOS v7 and gives administrators access to advanced features including:

• VLANs

• firewall

• NAT

• DHCP

• PPPoE

• hotspot

• VPN

• bandwidth queues

• multi-WAN

• failover

• load balancing

• dynamic routing

• scripting

• monitoring

Compared with normal consumer routers, RouterOS provides much more control.

The downside is that RouterOS also has a steeper learning curve.

Beginners may need time to understand:

• bridges

• VLAN filtering

• routing tables

• firewall chains

• queues

• interfaces

• PPP profiles

For experienced MikroTik users, however, this flexibility is one of the router’s greatest strengths.

MikroTik RB4011 for ISPs

The RB4011 is particularly attractive for smaller and medium ISP deployments.

An ISP can use it for:

• PPPoE

• subscriber routing

• bandwidth profiles

• VLANs

• firewall rules

• hotspot services

• multiple internet links

Its suitability depends on the actual workload rather than simply the number of customers.

Important factors include:

• total bandwidth

• number of subscribers

• firewall complexity

• queue configuration

• VPN usage

• packet size

• routing requirements

For larger networks, the RB5009 or CCR series may provide more headroom.

ISPs can also combine MikroTik networking with Tajira for subscriber and billing management.

RB4011 for PPPoE

PPPoE remains a common subscriber-authentication method for ISPs.

RouterOS allows the RB4011 to manage:

• PPPoE users

• PPP profiles

• address pools

• bandwidth limits

• authentication

• routing policies

For smaller deployments, subscribers can be managed directly in RouterOS.

For larger networks, centralized authentication such as RADIUS may be more practical.

RB4011 for Business Networks

The RB4011 is also an excellent business router.

A business can use it to create separate network segments for:

• staff

• management

• CCTV

• guest Wi-Fi

• servers

• VoIP

VLANs can be used to separate these services while firewall rules control communication between them.

This makes the RB4011 suitable for:

• offices

• hotels

• schools

• warehouses

• hospitals

• retail businesses

• multi-branch organizations

RB4011 for CCTV Networks

CCTV networks often become complicated as camera numbers increase.

The RB4011 can be used to manage:

• IP cameras

• NVR systems

• remote viewing

• CCTV VLANs

• VPN access

• multi-site connections

A dedicated CCTV VLAN can help keep surveillance traffic separate from normal office traffic.

This improves organization and can make security policies easier to manage.

Multi-WAN Review

Another strong use case is multi-WAN.

The RB4011 can be configured with:

• primary fibre

• secondary fibre

• Starlink

• LTE or other backup links

RouterOS can then provide:

• failover

• policy routing

• load balancing

For businesses that depend heavily on internet connectivity, this can reduce downtime.

VPN Review

The RB4011 is a much better VPN platform than entry-level MikroTik routers.

Possible uses include:

• remote employee access

• branch-to-branch VPN

• technician access

• secure CCTV access

RouterOS supports multiple VPN technologies, while the RB4011 platform provides enough processing capability for more demanding encrypted traffic.

Bandwidth Management Review

Bandwidth management is another area where the RB4011 performs well.

RouterOS includes:

• Simple Queues

• Queue Tree

• PCQ

• PPP profiles

These can be used by ISPs to define subscriber packages or by businesses to prioritize important services.

For example:

• VoIP

• cloud applications

• video conferencing

• ERP systems

can be prioritized over less critical traffic.

Build Quality

The RB4011 uses a solid metal enclosure.

This gives it a professional appearance and helps with heat dissipation.

The router is fanless, so there is no internal fan noise.

That makes it suitable for:

• offices

• server rooms

• network cabinets

• home labs

The lack of moving cooling parts can also reduce maintenance concerns.

Rackmount Design

The RB4011iGS+RM includes rackmount capability.

This is important for professional deployments where equipment needs to be installed neatly alongside:

• switches

• patch panels

• fibre equipment

• NVRs

• UPS systems

• servers

For installers and businesses, the rackmount design is a major advantage over desktop-only routers.

PoE Review

The RB4011 supports Passive PoE input and Passive PoE output on Ether10.

PoE output can help power compatible networking devices.

However, Passive PoE requires care.

Always verify the voltage requirements of the connected device before enabling PoE output.
