PNs need the onQ Proxy, not to be confused with onQ Central Proxy and PN Proxy or Proxy Host, to communicate with onQ for backups. PNs can share an onQ Proxy (aka global onQ Proxy) or each PN can have a separate onQ Proxy.

If you do not specify an onQ Proxy for the PN, onQ uses the global onQ Proxy. If you do not specify a global onQ Proxy, onQ uses its own IP address.

If you have any PNs on a different subnet, such as in a DMZ, you must specify an onQ Proxy on the PN itself. However, at the time of enrollment, the PN does not have a configuration so you cannot set its onQ Proxy until after enrollment. Therefore, before enrollment of a PN on a different subnet, you must temporarily set the global onQ Proxy to the onQ Proxy for that PN. After enrollment, revert to the global onQ Proxy.
