Help with port forwarding (again)
I know I've already asked a very similar question on the subreddit, but now that that's down in protest, I have to ask here instead.
I'm like many other Minecrafters: I want to host my own server. I have some knowledge of Linux and know how to hsot a server, but I'm not very familiar with the details of networking and so I'm struggling (like so many other people) to get my router to let people in, on a specific port. I've followed every guide I can and even the advice that was given when I asked this question originally. I have set up the static IP in my router's DHCP server settings, althought that probably isn't the problem because I can see my IP quite easily (linux) and it isn't changing much, despite my many restarts :^) I've tried
sudo ufw allow 25565
(linux version of "allow port 25565 on my firewall), to no avail, and I of course have the forwarding rule supposedly set up in my router's settings. I am happy to provide extra details, but here's what I think may be important:
Rule for forwarding Minecraft port

rule (if you care)
If you need any more information, I'm happy to provide it if I can.
Thanks in advance!29 Replies

We may have bad news for you :C
Open your router's configuration interface. Somewhere you'll see something like 'external' or 'public' IP.
If your external IP is in one of the following ranges, you're basically screwed as long as portforwards go:
- 10.0.0.0/8
- 172.16.0.0/20
- 192.168.0.0/16
- 100.64.0.0/10
- any IPv6 address/range - This shouldn't be a problem, but Minecraft's IPv6 support is still rather quirky. You're at your own but we're happy if you share your experience.
You should ask your ISP for a public and IPv4 address (but this may cost you money).
NB: your internal IP should and most probably will be in one of the first three ranges, don't mix them up

have u checked for this_
Yes
Public ip is 173.xx.xxx.xxx
I'm almost certain I'm not behind cgnat. Here's some tracepath output (afaict that's "just a single hop," which (according to that link) means I'm clear, but as i said, I'm no network wizard)
that seems fine, tho i am none either lol
Not public IP that you'd see from "what is my ip" but instead it would be the WAN port of your router.
https://rtech.support/docs/networking/port-forwards.html
Here is a good guide for port forwarding questions
Which I can't find on my router's page... It's not under "wan", "network map", "lan", etc.
my wan address isn't under wanHmmm
I have a ZenWiFi AC if that helps
I've gone through the rtech.support guide, and nothing applies/works from what I can tell. I didn't do a 100% thorough run-through, though, so it's possible, albeit unlikely, that I missed something.

It's all in there.
Page 56: 4.3.3 Virtual Server/Port Forwarding
And page 13: 2.1 Logging into the Web GUI
Basically you go to http://router.asus.com/, use
admin
as the username and password, go to port forwarding and add the port.Except.
I already have and it doesn't work 🙃
What's the exact problem?
@ZWORX52 Are you also still using your Verizon router as well? If you are, then you have two routers and would be behind double nat.
if this is the case, you can either
- Change your ZenWiFi AC into AP only mode
- Remove Verizon's router, there's a guide here: https://community.verizon.com/t5/Knowledge-Hub-Popular-Articles/Using-your-own-router-with-Verizon-Fios/ta-p/1696146
Can I make the AP only mode only affect my specific device?
i.e. there's a potential security risk that I'm removing and I'd like to minimize it to the unimportant (no bank info etc) linux device
no, AP mode would mean that the ZenWiFi AC would only serve as an ethernet switch/wifi access point, not nat, no routing, no nothing
Oh I see
if you want the features of that router, you should remove the verizon router, as long as you're not using verizon tv
I've been informed that the only job of the Verizon device is to turn the incoming fiber-optic signal into Ethernet signal. It's supposedly called a modem, but my parents seem unsure whether that's what its acual purpose is.
Wouldn't be a modem, but an ONT in this case
Would it still cause double nat?
nah, it wouldn't
it's not a router, just a dumb box that turns light into rj45
thinking about it, you would also likely see another hop in your traceroute if you were behind double nat
Whereas I seem to only see one (although it takes up two lines...)
So if that's not the problem, then what could be?
Can I ask a random question? What is it about 192.168 that makes port forwarding not work?
192.168.x.x
is a local IP, what's exactly the problem? Did you input that in the port forwarding's IP field?
Ping me when replying btw, otherwise it'll take very long for me to respond 😂@SaxorUltima
The problem with 192.168.###.### isn't a problem with the IP itself. The problem is where that IP is. If that is your routers WAN IP, you have double NAT. Which is a problem.
If your routers WAN IP is something that isn't a private IP address, and is the same as what you find on Google, you're fine.
