SBC Manager — Network Configuration
Network configuration has two parts: the application's identity settings and the operating-system network interfaces. Both are managed under Settings → Network.
Application Settings
| Field | Description |
|---|---|
| Node Name | Display name shown in the GUI and dashboard |
| Node ID | Lowercase identifier used in configuration (letters, numbers, hyphens, underscores only) |
| Management IP | IP address used for web GUI access and cluster communication |
| SIP IP | Public IP used for SIP and RTP traffic |
| Web URL | Full URL of the web GUI (e.g., https://sbc.example.com) |
Click Save application settings to apply. This updates the application configuration only — Asterisk is not affected.
OS Network Interfaces
The Server Network Interfaces section lists every detected network adapter. For each interface you can set:
- IP address
- Prefix length (subnet mask)
- Gateway (set on exactly one interface to define the default route)
- DNS servers
Click Apply & restart <interface> to write the configuration and restart that adapter immediately.
Warning: Applying changes to the interface you are currently connected through will restart it and redirect your browser to the new IP address. Verify the gateway is correct before applying — an incorrect gateway can cause loss of access.
On dual-NIC appliances, the recommended layout is one interface for management (web GUI, SSH, cluster traffic) and one for SIP/RTP.
