• Retail Networks
  Combine wired terminals and wireless networks using RB3011’s high port count and integrated management.

How to Optimize RouterOS on RB3011

1. Upgrade to the Latest Stable Version

Always start by updating your device to the latest RouterOS stable release:

• Go to System > Packages
• Click Check for Updates
• Choose the Stable channel and apply the update
• Reboot the router

2. Enable FastTrack for NAT

FastTrack drastically improves throughput for normal internet traffic:

• Go to IP > Firewall > Filter Rules

• Add a rule at the top of your list:

  • Chain: forward

  • Connection state: established, related

  • Action: fasttrack connection

⚠️ Don’t use FastTrack if you need detailed traffic accounting or QoS.

3. Use Bridge Filtering Wisely

If you’re using a bridge with multiple ports:

• Use hardware offloading where available (check with /interface bridge port print)
• Avoid complex filtering in the bridge to reduce CPU load

4. Disable Unused Services

Turn off services you don’t use to reduce attack surface and free resources:

• Go to IP > Services
• Disable: FTP, Telnet, and other unused services
• Only keep Winbox and SSH (with strong passwords)

5. Tune Connection Tracking

If you’re not using firewall tracking for certain traffic types:

• Go to IP > Firewall > Connections
• Adjust timeout values or disable tracking on specific interfaces (use mangle rules with connection tracking disabled)

6. Limit Logging Output

Excessive logging can slow down the system:

• Go to System > Logging
• Disable or reduce info, debug, or firewall logs unless necessary

7. Monitor Resources

Use System > Resources and Tools > Profile to identify bottlenecks:

• Look for high CPU loads
• If a specific process (like firewall or dns) consumes too much, optimize related rules or configurations

8. Use Address Lists for Efficient Firewall Rules

Instead of many rules with single IPs:

• Group IPs in Address Lists
• Reference the list in a single rule to reduce processing time

9. Optimize Queues (Optional)

For traffic shaping:

• Use Simple Queues only for basic needs
• For better control, set up Queue Trees but avoid using them if you’re relying on FastTrack

10. Secure Remote Access

• Change the default Winbox port
• Limit access to trusted IP ranges
• Enable 2FA on Winbox (optional via external tools)

Bonus: Use MikroTik Tools

• Torch: For live traffic analysis
• Ping & Traceroute: To test connectivity
• Netwatch: To trigger scripts on interface status changes

This setup ensures the RB3011UiAS-RM runs efficiently, securely, and performs optimally for both basic and advanced network environments.

Managing Redundant Internet Links

With RB3011, you can configure multiple WAN uplinks using ECMP or scripting for failover. Assign the primary link to port 1 and the secondary link to port 2, then use recursive routing checks to automatically switch if the main ISP fails.
