Networking is one of the hardest things in building working clusters of servers. It's also the most vulnerable parts of your hole setup. The WAN interface is under attack 24/7 - by professionals and military.
Proxmox
Our Proxmox lab shall be hidden away from the wife and kids. How to use Software Defined Networking SDN, VXLAN, OPNsense and a VM to run our Lab hided away from the family. Create a personal space for testing stuff. Use Pi-hole as an alternative to other DNS.

Security is very important, especially for home labs, we don't have the 24/7 IT-Security Staff to handle things. Several large attacks have recently been utilizing stolen credentials from home users. Yes, home labs are low-hanging fruit for hackers and especially wannabees.
Install
How-to configure networking on a Proxmox host. Using VLAN for segregation, bonding for fault tolerance and some other advanced things.
Install
As SSH is our mostly used tool, we need to make it safe.
Basics
SDN The Software-Defined Network enables the creation of virtual zones and networks (VNets) including a DHCP. This functionality simplifies advanced network configurations for home labbing. The benefits in a more responsive and adaptable network infra. #pve #sdn
Remote Access
Transparent proxy server that works as a poor man's VPN. Forwards over ssh. Doesn't require admin. Works with Linux and macOS. Supports DNS tunneling. sshuttle: where transparent proxy meets VPN meets ssh
Remote Access
The Jump Box, Host or Server or a Bastion Host or Server. By create a highly secured, The Jump Box with web access and use it to jump to servers on a internal and dedicated network we only have 1 server exposed to the web not 5. #2FA #TUI #TOTP
Build
For small servers we need tiny Kubernetes nodes like K0s. This is my how i repurposed an old wrecked laptop as an tiny min server running a Kubernetes cluster - K0s. #k0s

Networking
Proxmox Firewalls are there for a good reason. And they are on 3 levels, so take them seriously and put them on. Use a VLAN for the Management Interface. Practical section with examples.
Networking
After all the bad things pfSense brought to the table in the form of broken promises vi-a-vie the pfSense +, I think it's time for even me to start going with OPNsense. To make it more interesting I set it up using only one NIC. There is one use-case - the Data Center bare metal setups.
Networking
OpenWRT is one of the most popular router/firewalls in the world. Many ISP and WiFi router manufacturers uses it widely. It runs on mnimum HW and for that it's just what the lab needs. #openwrt #router #firewall
