VLAN configuration with Linux bridges, Proxmox firewall rules, fail2ban setup, SSH hardening, and network segmentation best practices.
Tagged or untagged? The answer depends on whether you need simple multiplexing across one link or true Layer-2 isolation between storage and guest traffic in Proxmox VE.
Most homelabbers overcomplicate their networking — here's how to get VLANs right the first time without adding unnecessary complexity.
Most people get VLANs right but leave their firewall wide open — here's the complete guide to actually segmenting your Proxmox network.
Most homelabs run everything on one bridge — until services collide. Here's how to segment them properly without adding hardware.
Most people treat firewall rules as an afterthought — here's how to harden your Proxmox cluster in under an hour without sacrificing usability.
Mirror your Proxmox bridge traffic to Suricata and get real-time network intrusion alerts without touching a single VM.
Stop writing duplicate firewall rules for every VM — apply IP sets and security groups to manage policies at scale.
Run cloudflared in a 512 MB LXC and reach your Proxmox UI from any browser with zero open ports on your router.
Give every VM and container a real IPv6 address in 20 minutes — without tunnels, NAT, or third-party tools.
A deep dive into CVE-2024-21545, the authenticated arbitrary file read in Proxmox VE that can be chained into a full root takeover — and how to fix it.
CrowdSec pre-blocks thousands of known attacker IPs before they reach your Proxmox node — here is the full cluster-ready setup.
Scoped API tokens take 20 minutes to set up and mean a leaked Terraform key never touches your root account.
Linux bridges cap out fast. OVS adds per-port VLANs, port mirroring, and VXLAN tunnels to Proxmox without swapping hardware.
Skip the browser SSL warnings — get a valid Let's Encrypt cert on your Proxmox node in under 15 minutes.
Password auth alone isn't enough. Add TOTP or WebAuthn 2FA to your Proxmox dashboard with this step-by-step setup guide.
LOLPROX exposed serious hypervisor attack paths. Here's a concrete checklist to close those gaps in your Proxmox setup.
Set up Proxmox Mail Gateway 9 as an email security layer to block spam and malware before it reaches your mail server.
Ditch the port forwarding. Set up Tailscale on Proxmox for secure, zero-trust access to every VM and container in your homelab.
Set up link aggregation and NIC failover on Proxmox VE to eliminate network single points of failure.
Run OPNsense as a dedicated Proxmox VM with NIC passthrough and VLAN trunking for a powerful, flexible homelab firewall.
Turn your Proxmox homelab into a real private cloud with SDN zones, VLAN isolation, and automated VM deployment.
Run WireGuard VPN directly on Proxmox or in a dedicated VM to get fast, encrypted remote access to your entire homelab.
Set up a full observability stack on Proxmox VE with Grafana, Prometheus, and Loki — all running in lightweight LXC containers.
Stop manually managing Linux bridges. Proxmox SDN gives you centralized, cluster-wide virtual networking in a few clicks.
Set up proper network segmentation with VLANs on Proxmox using Linux bridges and trunk ports.
Essential security hardening steps for Proxmox VE — firewall, fail2ban, SSH keys, and 2FA setup.
