Weighted connection distribution
Use PCC and routing policy design to distribute new connections according to configured weights.
MULTI-WAN SHIPBOARD GATEWAY
Intelligent routing for changing sea conditions.
A MikroTik RouterOS-based network gateway architecture that distributes traffic across multiple WAN connections and keeps local routing policies under vessel-side control.
SHIPBOARD EDGE
Flexible 4-WAN architecture
Build a practical gateway configuration around up to four assigned WAN interfaces and dedicated LAN connectivity, subject to the selected MikroTik model and port allocation.
StarlinkVSAT4G / 5GRouterOS 7
Reference architecture, not a certified or pre-tested product specification.
CORE CAPABILITIES
A gateway designed around your traffic policy.
The exact configuration depends on the vessel, satellite terminals, cellular modems and onboard applications.
Link health and failover
Monitor upstream reachability and apply failover or policy changes based on tested conditions.
NAT and network separation
Keep onboard LAN addressing stable while changing upstream WAN routes; established internet sessions may reconnect.
Per-WAN visibility
Read individual interface counters, throughput and health metrics for operational monitoring.
Traffic and cost policy
Prioritize connectivity by business class, link availability, data cost and project-specific rules.
Remote configuration
Update approved RouterOS configurations through secure management channels and documented procedures.
Important: Multi-WAN load balancing is not the same as true single-session bandwidth bonding. Changing WAN public IPs can interrupt active calls, VPN sessions or downloads. Dynamic link-quality scoring and seamless session continuity require additional design and testing.
REFERENCE TOPOLOGY
Shipboard architecture
A local gateway can manage WAN routes independently from cloud connectivity.

Design considerations
| WAN interfaces | Four designated WAN interfaces in a reference design; physical ports depend on hardware. |
|---|---|
| LAN / Wi-Fi | Separated LAN, VLAN and wireless networks according to vessel requirements. |
| Routing | RouterOS 7 policy routing, PCC / ECMP where appropriate. |
| Failover | Local route monitoring and fallback paths; behavior must be validated per WAN. |
| Management | Secure RouterOS API / SSH / VPN integration, subject to deployment design. |
| Hardware selection | MikroTik L009, RB5009 or other suitable devices after capacity assessment. |
