cr1000x,FTP,Alarms,hugues9502, Firewall, remote conexion


jhon Oct 9, 2021 12:01 AM

I need your help, I have a station with a cr1000x connected to a hugues 9502 satellite modem, this station sends data to an ftp, but the data consumption is very high.

we want to apply a firewall to restrict any consumption. There should only be data consumption when sending to FTP,alarms and remote connection through loggernet (connect).

What considerations should I have in order to achieve that the applied firewall can connect me to the station remotely.

ports, IPs,IPpublics, ...?

Greetings.

Some things you can do, in no particular order

* Use private IP and not public IP address. I.e. limit your uncontrollable, public exposure.

* If using H9502 on public IP, only forward IP ports required (for example, 6785). I.e. limit your public exposure.

* Power down H9502 when not in use. Either switch power or use pin 9 on GNSS port. I.e. if the unit is down, it can't use data.

* Instead of using PakBus/TCP client, consider using TCPOpen(), TCPClose() so you have complete control over outbound PakBus/TCP connections.

Just some thoughts.
