Understanding Gaming Network Requirements
The Gaming Traffic Trinity
Gaming networks require three critical metrics:
1. Low Latency (Ping)
- FPS games (CS:GO, Valorant): Under 30ms optimal, 50ms maximum
- MOBA games (League of Legends, Dota 2): Under 60ms optimal, 100ms maximum
- Fighting games: Under 20ms optimal, 40ms maximum
- MMO games: Under 100ms acceptable, 150ms maximum
2. Minimal Jitter
- Variation should not exceed 5ms
- Consistent 50ms ping beats variable 20-80ms ping
- Jitter causes rubber-banding and prediction errors
3. Zero Packet Loss
- 0.1% packet loss creates noticeable gameplay issues
- 1% packet loss makes competitive gaming impossible
- Modern games do not handle packet loss gracefully
Gaming Traffic Patterns
Different game types generate different network patterns:
| Game Type | Bandwidth (Up/Down) | Packet Size | Frequency |
|---|---|---|---|
| FPS Games | 30-100 Kbps | 60-150 bytes | 60-128 Hz |
| MOBA Games | 20-50 Kbps | 100-200 bytes | 30-60 Hz |
| Cloud Gaming | 15-50 Mbps | 1400 bytes | Continuous stream |
| Game Downloads | Max available | 1500 bytes | Bulk transfer |

Essential MikroTik QoS Configuration for Gaming
Basic QoS Setup Using Queue Trees
Queue trees provide better performance than simple queues for gaming. Configure the basic structure:
# Define your WAN interface and speeds /queue tree add name="Download" parent=global packet-mark=no-mark limit-at=90M max-limit=95M queue=default add name="Upload" parent=global packet-mark=no-mark limit-at=18M max-limit=19M queue=default # Create gaming priority queues add name="Gaming-Download" parent=Download packet-mark=gaming-down limit-at=10M max-limit=95M priority=1 queue=sfq add name="Gaming-Upload" parent=Upload packet-mark=gaming-up limit-at=5M max-limit=19M priority=1 queue=sfq # Regular traffic queues add name="Regular-Download" parent=Download packet-mark=regular-down limit-at=50M max-limit=85M priority=4 queue=sfq add name="Regular-Upload" parent=Upload packet-mark=regular-up limit-at=10M max-limit=15M priority=4 queue=sfq # Bulk traffic queues add name="Bulk-Download" parent=Download packet-mark=bulk-down limit-at=10M max-limit=70M priority=8 queue=sfq add name="Bulk-Upload" parent=Upload packet-mark=bulk-up limit-at=2M max-limit=10M priority=8 queue=sfq
Implementing CAKE Queue Type
CAKE (Common Applications Kept Enhanced) eliminates bufferbloat effectively:
# Enable CAKE queue type (RouterOS 7.x required) /queue type add name=cake-download kind=cake cake-bandwidth=95M cake-rtt=50ms cake-overhead=18 cake-nat=yes add name=cake-upload kind=cake cake-bandwidth=19M cake-rtt=50ms cake-overhead=18 cake-nat=yes # Apply CAKE to main queues /queue simple add name="WAN-Shaper" target=0.0.0.0/0 max-limit=19M/95M queue=cake-upload/cake-download
Traffic Marking for Gaming
Mark gaming traffic accurately using mangle rules:
# Mark gaming console traffic /ip firewall mangle add chain=forward src-address=192.168.1.50 action=mark-connection new-connection-mark=gaming-conn comment="PS5" add chain=forward src-address=192.168.1.51 action=mark-connection new-connection-mark=gaming-conn comment="Xbox" # Mark packets based on connections add chain=forward connection-mark=gaming-conn in-interface=ether1 action=mark-packet new-packet-mark=gaming-down add chain=forward connection-mark=gaming-conn out-interface=ether1 action=mark-packet new-packet-mark=gaming-up # Mark by DSCP values (many games use EF - Expedited Forwarding) add chain=forward dscp=46 action=mark-packet new-packet-mark=gaming-down in-interface=ether1 add chain=forward dscp=46 action=mark-packet new-packet-mark=gaming-up out-interface=ether1 # Mark common gaming ports add chain=forward protocol=udp dst-port=3074,3478-3480,27015-27030 action=mark-connection new-connection-mark=gaming-conn add chain=forward protocol=tcp dst-port=3074,27014-27050 action=mark-connection new-connection-mark=gaming-conn
Advanced MikroTik Gaming Optimizations
Game-Specific Port Configurations
Popular games use specific ports. Configure accordingly:
Valorant
/ip firewall mangle add chain=forward protocol=udp dst-port=7000-8000,8180-8181 action=mark-connection new-connection-mark=valorant-conn add chain=forward protocol=tcp dst-port=8393-8400 action=mark-connection new-connection-mark=valorant-conn
Call of Duty: Warzone
/ip firewall mangle add chain=forward protocol=udp dst-port=3074,3075,3076,20000-20099 action=mark-connection new-connection-mark=cod-conn add chain=forward protocol=tcp dst-port=3074,3075,3076 action=mark-connection new-connection-mark=cod-conn
Fortnite
/ip firewall mangle add chain=forward protocol=udp dst-port=5795-5847,9000-9100 action=mark-connection new-connection-mark=fortnite-conn add chain=forward protocol=tcp dst-port=5795-5847 action=mark-connection new-connection-mark=fortnite-conn
Dynamic Server Detection
Create address lists for game servers automatically:
# Detect and add game servers to address list
/ip firewall mangle
add chain=forward src-address=192.168.1.50 protocol=udp dst-port=!53,!123,!500,!4500 packet-size=60-200 \
action=add-dst-to-address-list address-list=game-servers address-list-timeout=1h
# Mark traffic to detected game servers
add chain=forward dst-address-list=game-servers action=mark-connection new-connection-mark=gaming-conn
add chain=forward src-address-list=game-servers action=mark-connection new-connection-mark=gaming-conn
FastTrack Optimization
FastTrack bypasses CPU processing but conflicts with QoS. Use selectively:
# Disable FastTrack for gaming traffic
/ip firewall filter
add chain=forward action=fasttrack-connection connection-state=established,related \
connection-mark=!gaming-conn connection-mark=!important-conn comment="FastTrack non-gaming"
# Accept all established connections
add chain=forward action=accept connection-state=established,related
Reducing Latency: Advanced Techniques
DNS Optimization
Fast DNS resolution reduces initial connection latency:
# Configure DNS caching
/ip dns
set allow-remote-requests=yes cache-max-ttl=1d cache-size=4096KiB max-concurrent-queries=100 \
servers=1.1.1.1,8.8.8.8
# Add static entries for common game services
/ip dns static
add name=steamcontent.com address=192.168.1.1 ttl=1d comment="Local Steam cache"
add regexp=".*\.valve\.net" address=192.168.1.1 ttl=1d
# Enable DoH for security without latency
/ip dns
set use-doh-server=https://cloudflare-dns.com/dns-query verify-doh-cert=yes

Best Practices and Common Pitfalls
Do’s
- Always test QoS rules during peak gaming hours
- Keep RouterOS updated to latest stable version
- Monitor CPU usage – stay below 80% during peaks
- Document all custom configurations
- Create configuration backups before major changes
- Use connection marking before packet marking
- Set queue limits to 95% of actual bandwidth
Don’ts
- Never use default firewall rules without customization
- Avoid complex regex patterns in firewall rules
- Don’t enable features you don’t understand
- Never disable connection tracking completely
- Avoid using simple queues for more than 10 users
- Don’t mix PCQ with other queue types incorrectly
Common Issues and Solutions
| Problem | Cause | Solution |
|---|---|---|
| High CPU usage | Complex firewall rules | Optimize rule order, use address lists |
| QoS not working | FastTrack enabled | Exclude gaming traffic from FastTrack |
| NAT type Strict | Missing port forwards | Enable UPnP or manual port forwarding |
| Wireless lag spikes | Interference | Change channel, reduce width, adjust power |
