I can't Port Forward!
I am trying to set up a Minecraft sever for me and my friends, but port forwarding is much harder on AT&T's modems, and I can't seem to get it to work..
My model's number is BGW210-700 and I have tried everything. I know it's a problem with the modem because when I go to a port checker tool like this one; https://www.yougetsignal.com/tools/open-ports/ it says that the port is closed (I use the default 25565 host port) even though the modem website says it is open.
I have been working on this for around 4 days now, and have reinstalled the Server software, disabled firewalls, followed ALL the tutorials, so please don't just link me the first answer that's in the database.

We can help, @NathanB.
Have you tried setting up the server, and are you having any problems accessing it? Is a device on your network going to be hosting the server, or is it hosted by a 3rd party?
Port listening or port scanning requests can get denied by our provided routers as a security measure, since malicious users can potentially use those requests to gain access to your network and/or devices.
If you haven't, try doing a hardware reboot on your gateway by unplugging it and plugging it back in.
Let us know if this helps, or give us more information so we know how to proceed.

A port scan may show the port is open, but the server on the opposite side may not be communicating back out.
AT&T's black box is such a clunky piece of disappointing software. You have your port forwarding setup correctly,
***BUT***
1) - You need to make sure that your device declaration "MCPC" as setup in the RG has an IP that matches what the MCPC's current IP address actually is. Chances are, unless you setup your "server" with a static IP address, the DHCP lease was reset and your MCPC has a different IP address from what is setup in the RG.
2) - I'm assuming MCPC is a Windows computer. You need to make sure the Windows Firewall has enabled that port and is allowing it in on all networks. I don't think this is an issue since you can get it to work from the LAN side of things, but just double-check.
3) - You don't need IP passthrough. Port forwarding is all you need.
