Network Settings¶
This section covers the network configuration of RansNet SD-WAN branch routers and gateways — interfaces, routing, wireless, redundancy, and connectivity tracking.
All settings described here are accessible under Device Settings → Network in the mfusion device management interface, or via the CLI on each device.
Interfaces¶
Configure the physical and logical network interfaces on the device. Each interface type has its own page:
| Page | Description |
|---|---|
| Ethernet | Layer-3 routed physical ports — IP addressing, MTU, VLAN sub-interfaces, link speed, and other interface settings |
| VLAN | 802.1Q tagged sub-interfaces for traffic segmentation across a shared physical port |
| Bridge | Software Layer-2 bridge combining multiple ports into a single switched segment |
| WWAN | Cellular modem interfaces (4G LTE / 5G NR) — APN, band lock, SIM configuration, and 5G mode settings |
| PPPoE | PPPoE client interface for ADSL/VDSL and fibre broadband connections that require PPP authentication |
| Wi-Fi as WAN | STA (station) mode — connect the built-in Wi-Fi radio to an upstream network as a WAN uplink |
DHCP¶
DHCP is configured per interface and supports three roles: DHCP server (assign addresses to downstream clients), DHCP client (obtain an address from an upstream server), and DHCP relay (forward DHCP requests to a centralised server on another subnet).
Routing¶
| Page | Description |
|---|---|
| Static Routing | Manually defined routes with optional reachability tracking for conditional route injection and failover |
| OSPF | Link-state IGP for dynamic route exchange with on-premise infrastructure or between branch routers |
| BGP | External BGP peering with ISPs or third-party routers — prefix advertisement, path selection, and multi-homing |
Wireless¶
Wireless Configuration covers the built-in Wi-Fi 6 (802.11ax) radios on UA, HSA and UAP series devices. Radios can operate as an access point (serving wireless clients), in EasyMesh mode (multi-hop self-healing mesh with UAP-520 access points), or in STA mode (Wi-Fi as WAN) to use an upstream Wi-Fi network as a WAN backhaul.
VRRP — High Availability¶
VRRP provides gateway redundancy by sharing a Virtual IP address (VIP) among a group of routers. The highest-priority member holds the VIP as MASTER; BACKUPs take over automatically on failure. Multiple VRRP groups per interface enable active/active load sharing across VLANs while maintaining full redundancy.
Tracking¶
Tracking is a reachability monitoring engine that probes a target host and triggers a configured action when connectivity is lost. It is used across multiple features to provide intelligent, condition-based behaviour:
| Context | Action on failure |
|---|---|
| Interface | Disable the interface |
| Static route | Withdraw the route from the routing table |
| VRRP | Withdraw from the VRRP group, triggering MASTER handover |
| PBR | Withdraw the policy-based routing rule |
| BGP | Withdraw the BGP prefix advertisement |
| WWAN | Reset the cellular connection or switch from 5G to 4G |
| System | Reboot the router (last-resort watchdog) |
