Lab 4: Network Configurations & Tools

Network Router

I'm using Mercusys AX1800 Dual-Band Wi-Fi 6 Router

DNS Server

I have a DNS server that running on a VM's with DNSMasq installed. It serves as a DNS forwarder,caching and as a DHCP server.

Following is the configs.

DNSMasq Configs

domain-needed
bogus-priv
no-resolv
server=8.8.8.8
server=8.8.4.4
local=/home-cloud01.lab/
listen-address=::1,127.0.0.1,192.168.1.3
expand-hosts
domain=home-cloud01.lab
dhcp-range=192.168.1.4,192.168.1.255,24h
dhcp-range=192.168.2.1,192.168.2.255,24h
dhcp-option=option:router,192.168.1.1
dhcp-authoritative
dhcp-leasefile=/var/lib/dnsmasq/dnsmasq.leases

As we can see, I set the listener address to 192.168.1.3 which means this is the endpoint I can use as my secondary DNS setting on any of my devices - PC's, laptops,mobile phone, smart home appliances etc.

The root domain is home-cloud01.lab.

At the time of writing this guide, I have multiple IP segmentations:

  • 192.168.1.4,192.168.1.255 within this range, I use it for Pyshical and VM's based appliances.

  • 192.168.2.1,192.168.2.255 within this range, I use it for the Kubernetes cluster
