Public IP to a Minecraft Server Port Forwarding

Hi,

 

So I'm trying to create a Minecraft server for my friends and I cause I'm a nerd. I've set everything up right Minecraft-wise, because the localhost works fine. However, trying to connect to a public ip doesn't work, so people not on my network can't join. I created the port forward like everyone says to do, but it didn't work. I'm planning on forwarding a domain I own (a GoDaddy .net) to the public ip so people don't have to enter using numbers. 

The problem is that my computer's IPv4 (because that's what I'm hosting it from) is 10.x.x.x, but my router's a 192.x.x.x. Everyone says that the IPv4 should be a 192.x.x.x and the Orbi should be 10.x.x.x. My Orbi is in router mode and my router is AT&T, which also supports custom port forwarding.

 

Does anyone know how I can set up my router and Orbi to allow people to join through the public ip?

Thanks in advance

Modem Combo Units:
This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT
Couple of options,
1. Configure the modem for transparent bridge mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

Re: Public IP to a Minecraft Server Port Forwarding

Is there a guide anywhere to explain how to do the first option? I'm not very experienced in computer hardware.

Re: Public IP to a Minecraft Server Port Forwarding

You'll need to contact the ISP to see if this option can be supported on there modem. Some modems don't support bridging so if thats the case, you can try option #2. Option #3 lastly.

Re: Public IP to a Minecraft Server Port Forwarding

Contact your ISP and have them help you bridge the modem. IF by chance the modem can't be bridged, try option # 2 or 3 of my listed suggestions for Modem/Router combo units.

Re: Public IP to a Minecraft Server Port Forwarding

I agree that putting your modem in bridge mode is the best (#1) but if that's not the case then you can also port-forward twice, once from the outside Internet through your AT&T router to the Orbi router and again from the Orbi router to your internal PC.  My own network is setup this way and I port-forward twice.

 

First figure out if you are in bridge mode by looking at your Orbi's Internet IP address.  At http://orbilogin.com/adv_index.htm does Internet Port - IP Address look llike 192.xx.xx.xx or 10.xx.xx.xx?  The latter means you are not using bridge mode and then the Domain Name Server's 10.yy.yy.yy address is likely how you get to your cable modem's admin web interface.

 

If you do need to port-forward twice then go to your AT&T modem's web control using 10.yy.yy.yy address and use it to forward your Minecraft port from 10.yy.yy.yy to the Orbi's 10.xx.xx.xx.  What brand of cable modem do you have, e.g., is it Motorola?  With this info we can help if you have trouble setting up your modem's port forwarding.

 

To test your final port-forwarding setup you can use https://canyouseeme.org/.  It tells you your outside internet public IP address.  You can also enter the port and it will tell you if the port is forwarded correctly, i.e., someone is listening and it is just blocked on the PC, versus a problem with the port forwarding.

My internet port is 192.x.x.x. What does that mean I have to do?

You have a router already in front of the Orbi router. 

Couple of options,
1. Configure the modem for transparent bridge mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

 

Easiest configuration would be option #3 for you.
