Hi everyone! I can't do port forward to an apache server. I own a TRB140, which contains a SIM and is connected to a switch via cable. A beaglBone Ai running Debian is connected to the same switch. An Apache server is running on Debian. A PC is also connected using a stick with a SIM card in the same APN network as the one from TRB.  But I can't get to the Apache Server using the SIM address on one port.

Hello,

Thanks for contacting TELTONIKA | Crowd-support forum.

Please note that the end device, default gateway IP should be specified in network configuration, without it, the port forward might not work.

In addition, public IP for the sim card is necessary for port forwarding to function.
