Overview of this book

This is not an instructional guide, but a practical, scenario-based book which guides you through everything you need to know in a practical manner by letting you build your own cluster. By the end of the book, you will have a fully functional Proxmox cluster setup at your disposal and have the knowledge to replicate virtualization solutions .If you already know what the word virtualization means and you are ready to stand out from the crowd equipped with the unique ability to design and implement a rock-solid virtualized network environment using Proxmox, then you have just picked up the only book you will need. Linux system administration experience together with knowledge of networking and virtualization concepts is assumed. This book is also useful if you are already using Proxmox and simply want to master its advanced features.

Adding NAT/masquerading

NAT is a way to hide internal network IP addresses from the external network, such as the Internet. Any outgoing traffic uses the main host IP address instead of using own local IP address. Add the last three lines of the following post-up and post-down settings in the configuration file /etc/network/interfaces. Only add these lines under the virtual bridge configuration which needs the NAT option. Have a look at the following code snippet:

auto vmbr0
iface vmbr0 inet static
address 192.168.145.1
netmask 255.255.255.0
bridge_ports none
bridge_stp off
bridge_fd 0post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up iptables -t nat -A POSTROUTING -s '192.168.145.0/24' -o eth0 -j MASQUERADE
post-down iptables -t nat -D POSTROUTING -s '192.168.145.0/24' -o eth0 -j MASQUERADE

Tip

It is much easier and manageable to handle NAT using a physical or virtual firewall. Most of the firewalls have the NAT option out of the box. Also, using virtualized firewalls, we can create...
