Network

Network shows the name the node answers to, how it is connected to your network and which proxies it trusts.

The Network page

Host

Section titled “Host”

The Host card shows the name the node answers to: its hostname, cluster and domain name, for example spica.virgo.univrs.cloud. Select Edit to change them.

Editing the host

If another node on the network already belongs to a cluster, the cluster and domain are locked to that cluster.

Interface

Section titled “Interface”

The Interface card shows the node’s network connection: its address, virtual IP, default gateway, DNS servers, MTU and MAC address.

The badge next to the virtual IP says which node carries it:

  • Holding: this node answers on the virtual IP.
  • Standby: this node shares the virtual IP, but another node holds it at the moment.
  • On followed by a node name: another node on the network has a virtual IP, and this node is not part of it.

Select Edit to change the IP address, netmask, virtual IP, default gateway or DNS servers. Use Add DNS for up to three DNS servers.

Editing the interface

The virtual IP is the address the node’s name, its apps and your router’s port forwarding point to, so it is shared by all the nodes in a cluster. It can only be changed on the node that holds it, or while no node on the network has one yet.

A node on standby

On a node on standby, the virtual IP is locked. The ? next to it explains which node holds it; to move it to this node, use Take over virtual IP on the Dashboard.

The virtual IP locked on a node on standby

If another node on the network has a virtual IP and this node is not part of its cluster, the field is locked too. Adopt this node from the Dashboard of the node holding the virtual IP, to share it instead of configuring a second one.

Trusted proxies

Section titled “Trusted proxies”

If you put another reverse proxy in front of the node, add its IP address here. The node then reads each visitor’s real address from the headers that proxy adds, such as X-Forwarded-For. That address decides, for example, whether a visitor counts as being on your local network. The node’s own proxy is already trusted.

Select Add and enter the proxy’s IP address.

Adding a trusted proxy

Open a proxy’s menu to Edit or Delete it.
