SBC Management IP configuration


This article explains how to modify the management network interface of FreeSBC and ProSBC

FreeSBC and ProSBC will come with a default mgmt0 port after installation. This interface needs to be configured to gain access to the web portal.
You can use the tbchangeip command to:

  • Change the IP address, subnet and gateway of the management port, or select DHCP.
  • Change the Domain name servers (DNS) used by the internal host (Used for updating Linux packages or other).

Command

Type this command from the console:

 tbchangeip

Follow the instructions.

Modify static IP address

This example changes the IP address to a static address with no DNS server

Do you want to modify the network settings (enter 'help' for usage) ?[No]                   --> yes
Do you want to modify mgmt0 ?[No]                                                           --> yes

  • Steps to modify the default gateway address (this is necessary to assign an IP address when in static mode.)
Would you like to modify the default gateway address ?[No]                                  --> yes
Enter default gateway ip address ?[]                                                        --> 10.0.0.1
