Trying to Port Forward a MC Server Can't Do It Properly/Don't Know How

[jacobweaver800]

Me and my friend are trying to setup a Minecraft server to play without needing to LAN. We have an old Dell PC and we have all the files and mods to get the server running but we can't get an IP address for it to open successfully, and every time we open it it just crashes. We have been binge watching Youtube videos for about a month now and we can't figure it out. Is there anything we can do to get it running properly.

System specs.
Pentium D 945 Dual-Core 3.4ghz
4Gb's DDR2 @533Mhz (won't run at the rated 800mhz)
Radeon HD 5450 Overclocked @700Mhz On the Core Memory @900Mhz (all stable)

To enter the game you need to use your public ip. The port forwarding should be setup to forward traffic coming in on the ports the docs say to forward and sent to the private ip of your dell pc. firewall at the dell pc needs to let traffic through. You can test that part by turning it off and on to check.

Your ISP could be blocking these ports, which is common on low tier consumer internet, it might be a feature of a faster pack or business grade. You may need to deal with them to get them open.

We have Frontier as our ISP ( I know...), we know it's our firewall blocking it, but even with it turned off we still can't access the server, the issue is when we give the server an IP address to use it won't start correctly and we are getting an error saying it couldn't bind to that port.

Did you make sure the router is in agreement with the static ip? Try using DHCP and then updating the port forwards for testing. The router might want you to release the ip for static use. Use ipconfig to check your ip. If you're using linux; you could also have permission issues if it thinks an unprivileged user is trying to access a program.

Is it because we are using unactivated Windows 10? I never thought if that could be why. We are actually fairly new to router stuff, we are also daisy chaining together 2 modems, we are using a really good Netgear router and that is being fed by the crappy Frontier one.

If you're using two NATs this will be highly problematic. I would suggest dropping one. If you need more ports use a switch. If you need the extra wifi try and turn it into a wireless access point (wireless switch)

Its not that we need the wifi from the second modem, its just we can port forward on our modem but we can on the other one, also the input on the good modem is an Ethernet port and it needs to be a DSL port so we can't just use the good one instead.

You can or can't from the modem/router combo? You will need to do it on that one or get it to only perform as a modem.

The modem given to us from our ISP can't port forward, but the second one can. Except the input on the second modem isn't DSL so we can't just plug that one in instead.

You will have to work with your isp to get equipment and ports open on their side. the port forwarding on the 2nd one isn't doing anything, because the first one is blocking it. You could just rent one if they won't help you.

Would it be better to buy a better modem or work with our ISP? It's not our ISP blocking it, its just the modem we have is too crappy to port forward on, I also have suspicions that modem is slowing down our possible speeds through wifi.

You are going to have to check with the ISP, because they have to connect to it. They might not allow third party ones. Running services is really a money grab for them, because it's easy to block and not many people use it. Even with a modem only, not a router combo, the ISP can still block these ports on their side.

I did some digging and it isn't blocked by our ISP, but we have to find our passwords for the modem we bought from them. I'll let you know if we have any more problems or questions.

If the modem/router has a passthrough feature then you can configure everything on your router.
