FEATURE DEEP DIVE

The full public-cloud network toolbox, on your racks

Isolated VPCs, managed load balancers, account-owned certificates and firewalls that enforce down to the hypervisor. Every public resource gets a real hostname automatically.

01

VPC networking

Isolated private networks that span hypervisors, with redundant gateways.

VXLAN overlay

Multicast or unicast mode per hypervisor group, so VPCs work in datacenters where multicast is unavailable.

NAT gateways

Managed NAT with per-GB bandwidth billing, configurable accounting and automatic overage enforcement. Keepalived redundancy across nodes.

IPv4 & IPv6 subnets

Full dual-stack subnet management, with per-interface speed controls set per group and overridable per plan.

VPN gateways

Site-to-site tunnels and road-warrior clients that receive the VPC’s private DNS resolver automatically.

Private DNS that resolves

VPC search domains ship with the link, and the gateway resolver always runs, so private names resolve on first lookup.

Hot attach & detach

VPC NICs attach and detach on running instances, on KVM and Proxmox alike.

02

Managed load balancers

HAProxy under the platform’s control, hardened by three years of production fixes.

SSL termination & health checks

TLS at the edge, active health checks with a configurable Host header, session stickiness and connection draining.

Host & path routing

Rules match on request host as well as path, so one load balancer serves several hostnames to different backends.

Static IPs & idle timeouts

Deploy onto allocated static IPs so the address can be firewalled and DNS’d before the LB exists. Per-frontend idle timeouts keep SSH and database sessions alive.

Self-healing configuration

A stranded load balancer recovers on its own, stale callbacks can never overwrite newer state, and one bad certificate never blocks a listener.

03

Account certificates

TLS certificates as account-owned objects, like AWS ACM.

One store, every listener

Upload a certificate or issue one from Let’s Encrypt once, then reuse it across every listener that needs it.

SNI on :443

A listener holds an ordered set of certificates, one default plus any number served by SNI. Two domains share one IP.

Validated & monitored

Uploads verify key match and CA chain, expired material is rejected, and expiry alerts page you before a certificate lapses.

04

Firewalls & security groups

Layered enforcement from the panel down to the hypervisor.

Per-instance rules

Inbound and outbound rules applied in real time, with IP sets for reusable address lists.

Accept and drop

Explicit drop rules override broader accepts, consistently on KVM and Proxmox.

Anti-spoofing

IP filters pin each NIC to its assigned addresses, so a guest cannot impersonate its neighbors.

05

DNS

Provisioning produces real hostnames, not bare IPs.

System DNS

Every public instance, database, load balancer and control plane gets a hostname at provision time, with matching PTR records where the reverse zone allows.

Delegation wizard

Base domains onboard through a four-step wizard with real verification: a random record is written and confirmed through public resolvers before anything publishes.

Trusted TLS for databases

A Let’s Encrypt wildcard per base domain lets customers connect with verify-full against the public trust store.

Provider integrations

PowerDNS, ClouDNS and Cloudflare wired into the panel, plus a self-contained PowerDNS deployment kit for authoritative DNS fleets.

Deeper look

Load balancers and DNS, one level down

A single load balancer's frontends and health checks, next to the domains System DNS manages behind every public resource.
