How To configure DHCP server on Ubuntu system

This tutorial will show you how to configure the DHCP server to work with Ubuntu. Before you start, make sure you already has the webmin and DHCP server installed on your system. Ok, lets start of with the DHCP. If you need the instructions of installing webmin, you can read it here.

1. Log in to your webmin by going to https://localhost:10000. This is done when you connect to your local server. If you have the remote server, you need to change the localhost with the name of your server.

2. On the webmin window, go to Server then DHCP. Click on Add a new Subnet and fill the required details. On the network address, use the same IP with internal server IP but use 0 as the ending octet. For example if your internal IP is 192.168.1.1, then use 192.168.1.0 for your network address. For address range, use the range of address to be assigned by the DHCP server. For netmask use the same netmask with your network, 255.255.255.0, then finally click Create.

3. Once created, click the new icon that was just created. Scroll down to the bottom and click Edit Client Options. Fill in the subnet mask with the subnet, the default routers and DNS server with your internal IP but with 255 at the end. Click SAVE and start your server.

Now you have a working DHCP server with your Ubuntu. Have fun
