I can't for the life of me get port forwarding to function through this new terrible Bluecurve modem. I've enabled bridge mode and set up the port forwarding on my 3rd party router (a TP-Link AC 1750), and nothing seems to be able to connect through that port. I am attempting to set 25565 (the Minecraft server port).

In the Bluecurve's web UI it still shows it having its own DHCP WAN IP address which seems strange, because if it's in Bridge mode shouldn't it just be acting as a "dumb" modem?

If anyone has any insights, please help, this is driving me mental.
