Policy-Based Routing (PBR)

Policy-Based Routing (PBR) allows administrators to precisely control how traffic is routed across multiple WAN connections—based on business intent rather than default routing rules.

Instead of sending all traffic through a single Internet link, PBR enables traffic to be intelligently steered through specific groups of WAN interfaces according to user-defined policies.

WAN Interface Groups

With 7G Fuse, users can:


  • Create WAN Groups by combining one or more WAN interfaces
    (e.g., Fiber + 5G, Dual ISP, Backup LTE links)
  • Assign traffic policies to these groups
  • Ensure traffic always exits through the intended WAN path

This abstraction simplifies routing management and ensures consistency across policies.


Rule-Based Traffic Steering

PBR rules can be created using multiple traffic attributes, including:


1. IP-Based Policies

Route traffic based on:

  • Source IP address (specific device, subnet, or VLAN)
  • Destination IP address (remote servers, cloud services, data centers)

Example:
Route traffic from the finance subnet to a dedicated MPLS or primary ISP link.


2. Port-Based Policies

Route traffic based on:

  • Source port
  • Destination port (application or service-specific)

Example:
Send VoIP traffic (SIP/RTP ports) through the lowest-latency WAN group.


3. URL & Domain-Based Routing

7G Fuse supports URL and domain name–based Policy-Based Routing, allowing specific internet services to always use a designated WAN group.

Administrators can:

  • Define policies using domain names or URLs
  • Bind those domains to a specific WAN group
  • Ensure all traffic related to those domains exits only through the assigned WAN links

Example use cases:


  • Route Microsoft 365 / Teams / Zoom traffic through a high-quality fibre link
  • Force cloud backups or large downloads through a secondary or unlimited WAN
  • Route business-critical SaaS applications over the most reliable connection
Key Benefits
  • Application-aware routing without changing end-user behaviour
  • Optimized performance for critical services
  • Cost control by steering traffic away from expensive links
  • High availability, with seamless integration into multi-WAN and failover setups
  • Granular control at IP, port, and domain levels
