Test setup with Virtual Box

To set up a test environment for DHCP server you need:

• Linux host machine
• Virtual Box
• Virtual machine (guest OS doesn't matter)

Configure client

1. Install Virtual Box and run the following command to create a Host-Only network:

    $ VBoxManage hostonlyif create
   

   You can check its status by ip a command.

   You can also set up Host-Only network using Virtual Box menu:

    File -> Host Network Manager...
   

2. Create your virtual machine and set up its network:

    VM Settings -> Network -> Host-only Adapter
   

3. Start your VM, install an OS. Configure your network interface to use DHCP and the OS should ask for a IP address from our DHCP server.

4. To see the current IP address on client OS you can use ip a command on Linux or ipconfig on Windows.

5. To force the client OS to request an IP from DHCP server again, you can use dhclient on Linux or ipconfig /release on Windows.

Configure server

1. Edit server configuration file 'AdGuardHome.yaml', for example:

    dhcp:
      enabled: true
      interface_name: vboxnet0
      dhcpv4:
        gateway_ip: 192.168.56.1
        subnet_mask: 255.255.255.0
        range_start: 192.168.56.2
        range_end: 192.168.56.2
        lease_duration: 86400
        icmp_timeout_msec: 1000
        options: []
      dhcpv6:
        range_start: 2001::1
        lease_duration: 86400
        ra_slaac_only: false
        ra_allow_slaac: false
   

2. Start the server

    ./AdGuardHome
   

   There should be a message in log which shows that DHCP server is ready:

    [info] DHCP: listening on 0.0.0.0:67
