Proxy and server via Internet

[andreagx]

Hello,
We have an internal Zabbix in HQ.

Now we have some branch office and we would install proxy to send data to the server in HQ (at night)

Is it possibile to do it by internet? What ports I need to publish?

tnx

It does not work in a way, that you exchange information just once a day...
Collected data is sent away at least once an hour in case of active proxy and with passive proxy its also at least once an hour data is pulled from proxy.
You need to kill connection completely and set offline buffer to some longer period (up to 720h) to kind of achieve that once a day situation.... but it is really not meant to work that day...
