Hi,

I'm trying to use a Dynamic DNS (Dyn.com) and ports forwarding on a TRB-140. I have to connect remotly a software to a device who work with static IP(192.168.2.211 in my example) on port 10002 and 30704. I'm configuring TRB-140 via USB port, device connected on TRB-140 ethernet port, it works fine but when i disconnect the USB port the connexion stop and don't restart. I had try with TRB1400_R_00.01.05 and TRB1400_R_00.01.06.1 firmware. I'm probably missing something...Can you help me? Some status and config screen shoot below. Thanks.

Hi,

When you're saying "connection stops and don't restart", you're meaning connection between TRB and device which is connected to TRB's LAN port (with IP 192.168.2.211)?
Or for example, you're also unable connect to TRB WebUI via DDNS domain?
It looks like TRB also have public IP address, if you would connect to TRB WebUI and navigate to System -> Administration -> Diagnostics and Ping LAN device's IP (192.168.2.211) will the pings goes through?

Also how about TRB configuration via Ethernet port? Are you able connect to TRB via Ethernet port and configure it?
