Can't reach a remote divice cRIO

Hello everybody,

I am not very practical with this forum so I will relaunch my issue, as I didn't receive any reply. If I am not using this forum in rong way I will appreciate any suggestion in that way even.

I have a cRIO9022 on my LAN which I can connect to with the MAX application installed on my PC. That works fine.

I have to place the cRIO in a remote location which I can reach from my LAN through the Internet, by means of a WiFi modem-router in the remote location, connected to the cRIO.ng to reach

Now I cannot anymore connect to the cRIO9022.

My doubts:
1) Is there any guided procedure to establish the connection from MAX to the remote cRIO?

2) Do I have to set any particular rules regarding the rules of the remote router-modem? I have tried to do port forwarding but I do not know what ports MAX SW is using to reach the cRIO.

Thanks to everyone that can give me a hint with this issue, even partially!

Nice day,

G
