Configure Network on NetBSD

Introduction link

The network is an essential part of system configuration. I will cover some aspects of it here.

Configuration link

Display Interfaces and Associated IPs link

Here’s the command:

  ifconfig
  

Static IPs link

We can declare interfaces persistently:

  [...]
# Add local overrides below
#
ifconfig_vr0="inet 192.168.0.254 netmask 255.255.255.0" # Wan
ifconfig_vr1="inet 192.168.1.254 netmask 255.255.255.0" # DMZ
[...]
  

You add an ifconfig entry with the interface name, followed by its parameters.

Gateway link

It’s possible to set the gateway like this:

  [...]
defaultroute="192.168.0.138"
[...]
  

Or alternatively:

  192.168.0.138
  

Restart Network Services link

  /etc/rc.d/network restart
