Port forwarding networking
If you don’t have a modem/router combo, they’re probably using carrier-grade NAT. Based on what I mentioned earlier, you might be able to get a public IP address. You could also consider renting a VPS, setting up a VPN server, and tunneling into it—though this usually involves costs. The VPS option isn’t something I’m familiar with. A simpler alternative might be to rent a Minecraft server and handle things that way.
No, that's not correct. 78.x.x.x isn't a private IP address; it's a public one. This likely means your external IP. You should update your post and remove any screenshots or sensitive info. It seems you're mixing internal and external IPs—your internal IP should fall within one of the private ranges (10.x.x.x, 172.16.x.x–172.31.x.x, or 192.168.x.x). Your external IP must be outside these ranges to be accessible by others, which matches what you mentioned. If I check the WHOIS for that IP, it shows "Telenor Sverige AB," confirming it's your public address.
Thanks to @Eigenvektor for noticing this. I believe you identified the issue. It seems you assigned your WAN IP as the internal IP for the server. Your internal IP should be something like 192.168.1.x, or at least match the private address most routers use. You need to either set a static IP on the server or reserve the IP through your router's DHCP server. A) Change the server's internal IP to the one assigned for it. For testing, make sure the Minecraft server is running. Also, avoid exposing your WAN IP publicly—this could expose you to DDOS attacks.
Yes, it looks correct. You’ve cleared the previous screenshots of your public IP. Thanks for pointing that out. Setting a static IP is straightforward—just use the option in your router’s settings and follow the instructions provided.
There are two options. 1) Configure a reservation in your DHCP server. I’m not sure where those controls are on ASUS devices. 2) Manually assign an IP address on the server. The problem is that any address you choose must be outside the DHCP range. The specific address the server uses varies by router. For instance, on Linksys models in the past the DHCP pool began at 192.168.1.100, allowing us to use static IPs from 192.168.1.2 through 192.168.1.99. My current router has the DHCP server starting at 192.168.1.2, so I had to adjust those settings for my devices. In either case, you need to locate the DHCP configuration. The simplest approach is to set a reservation for that machine.
Donut417, please revise your earlier comment and delete the screenshot containing the IP from your quote. @Vixiit, if you select "LAN" in your router's menu, you should find a tab named "DHCP server." As Donut417 mentioned, you can assign an IP manually, but setting up a static IP on the DHCP server is probably easier. On the DHCP server page, look for a section labeled "manual assignment." If the server provides addresses from 2 to 254, narrow that range down to something like 100 to 254—unless you have many devices, this should suffice. After adjusting, turn on manual assignment and input the server's MAC address along with the desired IP. Ideally, choose an IP outside the DHCP range, such as 192.168.1.5. To obtain the MAC address, right-click the network icon in the taskbar and select "Open Network & Internet settings." You'll see the network status, then click "View hardware and connection properties." This will display a line called "Physical address (MAC)." It should resemble aa:bb:cc:dd:ee:ff.
