Seperate servers (with different locations - one in LAN,one with Hetzner, one with OVH) that provide intranet (only available in the HomeLAN or via Wireguard), extranet(“public” services as in “to friends and family”) and Backup/Monitoring services.

Everything behind OPNsenses, with strict firewall rules, crowdsec and acting as a reverse proxy. Additionally certain things are locked down via hosting provider based firewalls (as I have the luxury to have a static IP at home I can easily do limit ingress for some extranet services)

VLAN seperation both within HomeLAN and Proxmox. Proxmox firewall rules to limit intra VLAN access. Unpriviliged LXC containers - seperated per service. Anything needing docker runs in rootless podman within an unpriv. LXC. (If it does not run like that it won’t run. End of discussion) Authentik for OIDC. If it does not do OIDC/SAML is does not run. (Only exception is LDAP in HomeNet as I am running free IPA anyway) Also acts as Jumpserver via VNC/RDP.

As I am using ansible/Terraform (via Semaphore) for everything I also strictly enforce fail2ban and certain monitoring components. (Namely Zabbix and Wazuh)
