Getting live data through a firewall

Getting live data through a firewall

By default, CIUMon listens on port 5099. In order to connect to CIUMon from across a firewall, this port must be unblocked to allow UDP communication.

In a simple setup, each instance of Hyperview connects to CIUMon across the firewall.

To avoid having user connections that must be allowed through the firewall, CIUMon can be run in relay mode or collector mode on a computer outside the firewall. This CIUMon connects to the main CIUMon through the firewall, and live data users connect to the relay or collector mode CIUMon.

The live data users do not need connections through the firewall.

If your firewall rules require the upstream CIUMon to initiate all communications, you may use collector mode instead of relay mode. As in relay mode, CIUMon will accept requests for data to pass along to an upstream CIUMon. In collector mode, however, CIUMon does not initiate any communication with the upstream CIUMon; instead, it waits for that CIUMon to ask for requests.
