Proxmox Virtual Environment Complete Course Part 13 - Networking

Introduction to Networking in Proxmox

In this section, the speaker introduces the topic of networking in Proxmox and explains its importance.

Networking as a Favorite Topic

• The speaker expresses their enthusiasm for networking and enjoys connecting hardware, setting up rules, and routes.

• Networking is an important aspect of Proxmox.

Importance of Separating VM Network and Management Network

• The speaker emphasizes the significance of separating the VM network from the management network.

• It is considered a good practice to have separate networks for virtual machines and management purposes.

Hardware Requirements and Network Setup

This section discusses the hardware requirements for following along with the tutorial and highlights the need for an existing network setup.

Hardware Requirements

• Not all viewers may have the required hardware for certain topics covered in the series.

• If unable to follow along due to hardware limitations, taking notes while watching is still beneficial.

Existing Network Setup

• Having an existing network is helpful for understanding networking concepts in Proxmox.

• Viewers are encouraged to use their own networks or create virtual networks if possible.

• VLANs and subnetting are mentioned but not covered extensively due to variations in routers/firewalls among viewers.

Adding Additional Networks on Individual Hosts

This section focuses on adding additional networks on individual hosts in Proxmox.

Setting Up Additional Networks

• To add another network, click on the desired host and then select "Network."

• Creating a cluster is not necessary at this point.

Configuring Network Bridge

• A specific network card (e.g., enp5s0f0) can be assigned to a different network by creating a bridge.

• The speaker prefers using a 10-gigabit port for the new network.

• Separating the management layer from virtual machines is recommended for security purposes.

Creating a Linux Bridge

This section explains how to create a Linux bridge for the additional network in Proxmox.

Creating a Linux Bridge

• Click on "Create" and select "Linux Bridge" to create a bridge.

• The default name assigned is vmbr1, but it can be customized if desired.

The transcript does not provide further details beyond this point.

Setting up the Subnet and VLAN

In this section, the speaker explains how to set up the subnet and VLAN for the network configuration.

Configuring the Subnet and VLAN

• Determine your network classification and create the appropriate subnet and VLAN.

• Type in the subnet details, such as "10.10.10.0/24," based on your network setup.

• Ensure that you have already created the subnet and VLAN on your end.

• If you haven't created them yet, don't worry; you can still follow along by watching the video and taking notes.

• It's good practice to have multiple networks, but it's not required for this setup.

Adding Ethernet Adapter Port to Bridge

This section focuses on adding an Ethernet adapter port to a bridge for network configuration.

Adding Ethernet Adapter Port

• Identify the port of the Ethernet adapter that you want to use for bridging.

• Type in the port name, such as "emp5s0f1," in the designated field.

• Add a comment if desired (e.g., vmnet).

• Click "Create" to complete the process.

• Note that there is no need to add another gateway since Proxmox only requires one gateway.

Applying Configuration Changes

Here, we learn about applying configuration changes in Proxmox.

Applying Configuration Changes

• Review any pending changes shown on the screen.

• Choose whether to apply them immediately or wait until rebooting the server.

• To apply changes now, click "Apply Configuration" and confirm with "Yes."

• After applying changes, two bridges will be displayed, with one active and ready for use.

Configuring Virtual Machine Network

This section explains how to configure the virtual machine network in Proxmox.

Configuring Virtual Machine Network

• When creating a virtual machine, select the appropriate network for it.

• In the networking section of the virtual machine creation process, choose "Network."

• By default, it may be set to vmbr0 (management network), but change it to vmbr1 (virtual machine network).

• Ensure that future virtual machines are created on the proper network for separation between management and VM networks.

Verifying IP Address Assignment

Here, we verify if the assigned IP address is correct for a virtual machine.

Verifying IP Address

• Access the virtual machine's console or log in remotely.

• Check if a new IP address has been assigned.

• Confirm that the IP address is on the desired network (e.g., 10.10.10.206).

Best Practices and Next Steps

The speaker discusses best practices and hints at upcoming topics related to Proxmox.

Best Practices and Next Steps

• It is recommended to separate management and VM networks as a best practice.

• Networking configuration opens doors to other exciting features like shared storage clustering.

• The next video will cover setting up shared storage, which promises to be interesting.
