Fastest way to get started with Pangolin using the hosted control plane. No credit card required.
A host private resource exposes a single machine on your remote network to connected Pangolin clients. When a user connects with the Pangolin client and has access to the resource, traffic destined for that host is carried over the tunnel to the site, which delivers it on the remote network. Host resources are the most common private resource type. They do not render in a browser—you use native applications (a database client, curl, an RDP client, etc.) against the destination address while the Pangolin client is connected.

​
Destination

Every host resource has a destination: a single IP address or fully qualified domain name (FQDN).
Destination typeExampleWhen to use
IP address10.1.0.35A host with a stable IP on the remote network
FQDNdb.autoco.internalA host identified by DNS that may change IP
Loopback127.0.0.1A service running on the site connector host itself

​
Loopback on the Site Host

If the service runs on the same machine as the site connector, set the destination to 127.0.0.1 or localhost. On the user’s machine, localhost always refers to their own computer—not the remote site. You must add an alias (for example metrics.site-internal.example) so users connect to a name that Pangolin resolves over the tunnel.

​
Port Restrictions

By default, all TCP and UDP ports on the destination are reachable. Tighten access with port restrictions to allow only the ports your application needs.

​
Multi-Site Routing

Attach multiple sites to a host resource when the same destination is reachable from more than one connector. Pangolin routes traffic through the best available site and fails over automatically when a site goes offline.

​
Aliases

Optionally assign an alias so users connect with a memorable hostname instead of a raw IP. Aliases are required for loopback destinations and recommended when the same IP exists on overlapping networks across sites.
