feature: the router has a two-level CA with an optional offline root, issuing CAs for P2S, site-to-site and general use, templates, published certificates and CRLs and an ACME server, site-to-site connections authenticate with certificates, and setup installs Caddy from Ubuntu or Caddy's repository.

 Description: Linux VPN router with IPSec, road-warrior, OpenVPN and WireGuard support
  Configures a Linux host or virtual machine as a VPN router: site-to-site
- IKEv2 IPSec (strongSwan swanctl), optional road-warrior access using EAP-TLS,
- optional OpenVPN with a certificate and a password per user, kept in a local
- LDAP directory, optional WireGuard, and the routing, NAT, MSS clamping and
- firewall rules a router needs. It keeps metrics of the router in PostgreSQL
- and serves them for an OpenTelemetry Collector, and makes scheduled backups
- to a local folder, copied to the cloud with rclone, or to a Proxmox Backup
- Server. Nothing in the package is
- specific to a cloud provider.
