Charging station on different network than Cerbo GX

Hello,

I installed 2 Charging station NS, and connected them to my Wifi network.

I have a Cerbo GX connected to my Ethernet network.

My Wifi and Ethernet networks are separated by a router / firewall.

I opened the TCP 502 port from the Charging stations to the Cerbo GX.

I manually set the Cerbo GX IP and the VRM portal ID in each Charging station.

It works on the Charging stations side: they can communicate with the Cerbo GX, display the battery state, the solar state…

But on the Cerbo GX side, it doesn't see the Charging stations. Do I have to open some ports from the Cerbo GX to the Charging stations too? @Lucian Popescu (Victron Energy Staff): maybe you have the info?

I also don't see the Charging stations on the VRM, but I guess they will show once the Cerbo GX will see them.

Thank you

I believe the easiest way would be to configure that router as a bridge. So both devices will be in the same network.

@cyril-ev Try opening port 502 from the GX to the Chargers as well, this should do the trick.

@Philipp Trenz thank you, I'll try this. I'll probably run into an other problem, as I'll need to add a route for this (the default router in the Cerbo GX can't access to the Wifi network…).

That would be cool to have (in the documentation) a list of ports to open when all things are not in the same network.
