solution for cgnat

i need a solution to port forward from home server running win11 over network while connected to a cgnat network

xB4CKD00R•63d ago

only need to port forward tcp/udp

DirtyJ•63d ago

If you're behind a nat that you can't control, then port forwarding directly to a public IP may not be an option. However, if your ISP provides you with a public IP (instead of them distributing one IPv4 address to several homes), then it would be a lot easier. In those cases, something like tunneling (e.g. with Cloudflare tunnels) or using a VPN that allows for port forwarding would be an easier option. All depends on what you have control over with the network devices you own

xB4CKD00R•63d ago

i have no public ip thats the issue detected ip in router is different from the one assigned to me

DirtyJ•63d ago

Then unless you can get the ISP to forward a port that you've already forwarded through the routers in your control, you won't have direct access to forward the port all the way out

xB4CKD00R•63d ago

look at this its insane

xB4CKD00R•63d ago

xB4CKD00R•63d ago

its actually 3 hops from the first router to network cause 192.168.192.1 is my antenna

DirtyJ•63d ago

None of those are public IPs

xB4CKD00R•63d ago

i know im showing u how the nat is working theres no way to port forward through all this

DirtyJ•63d ago

Not unless you have control of each device along the private hops

xB4CKD00R•63d ago

i dont for the 3 censored ones its isp

DirtyJ•63d ago

Then they would need to forward the port for you, which given the scenarios that a cgnat is used in, I find that unlikely to happen

xB4CKD00R•63d ago

exactly so whats the solution

DirtyJ•63d ago

Tunnel or VPN

xB4CKD00R•63d ago

for free whats available and how many ports? i mean i dont know any of these and wanna spend well if i have to pay lol

DirtyJ•63d ago

Cloudflare is free if you own a domain (standard domains ain't that expensive in the grand scheme of things)

xB4CKD00R•63d ago

i mean is that the best way to host for example steam servers from home server? i ll usually use from 5 to 6 ports tcp/udp

DirtyJ•63d ago

Here's some services that can do what you're looking for with varying price tags: https://www.zerotier.com/ https://ngrok.com/ https://portmap.io/ https://playit.gg/ I've only ever used the first two

ZeroTier | Global Area Networking

ZeroTier enables secure, modern overlay networking for the Internet of Things, Industrial IoT, RMM, Remote Access, Embedded Networking, SD-WAN, VPN, and more.

ngrok | Unified Application Delivery Platform for Developers

ngrok is a secure unified ingress platform that combines your global server load balancing, reverse proxy, firewall, API gateway and Kubernetes Ingress Controller to deliver applications and APIs.

Portmap.io

Portmap.io - free port forwarding solution

Expose your local PC to Internet from behind firewall and without real IP address

xB4CKD00R•63d ago

zerotier is basically a hamachi? lol

DirtyJ•63d ago

Correct

xB4CKD00R•63d ago

nah i dont want that lol

DirtyJ•63d ago

Except not run by logmein Lmao

xB4CKD00R•63d ago

i want something that leads to www network not a virtual lan xD

DirtyJ•63d ago

The other three are more public facing

xB4CKD00R•63d ago

ngrok and portmap?

DirtyJ•63d ago

Correct

xB4CKD00R•63d ago

which one is better ? lol

DirtyJ•63d ago

I've seen a lot of folks use ngrok and recommend it, I just found the other two while Google searching

xB4CKD00R•63d ago

i see thanks ll test and let you know

DirtyJ•63d ago

Best of luck :Salute:

xB4CKD00R•63d ago

is there a way to make the ngrok ip always the same also how to make it tcp and udp both its different ip for each tcp and udp port wont work like that lol maybe the best solution is really use a domain

w33t•63d ago

Ngrok will give you a domain and I think there is a way to do a custom domain or at least a static one. I believe there is another service that lets you being a custom domain, but I'll have to go digging for it

xB4CKD00R•63d ago

and probably its paid :pepehehe:

w33t•63d ago

Yes, things aren't free to run and operate

w33t•63d ago

https://localhost.run

localhost.run | localhost.run

xB4CKD00R•63d ago

hmm so many choices i honestly dont know what to choose anymore

DirtyJ•63d ago

https://wheelofnames.com/

Wheel of Names

DirtyJ•63d ago

fr tho probably just look through those and find one that is the closest to your budget and give it a shot weird nats = weird solutions

xB4CKD00R•63d ago

Just give me your opinion Cheapest and best solution to port forward ports from win11 TCP UDP What would you do

DirtyJ•63d ago

I'd go down the list, try ones until one works

xB4CKD00R•63d ago

Can't pay and just abandon it Lol

DirtyJ•63d ago

some of them have free tiers or trials

xB4CKD00R•63d ago

Should I just use cloudflare? And buy a 1$ domain

DirtyJ•63d ago

Cloudflare tunnels are more for these types of applications: https://developers.cloudflare.com/cloudflare-one/applications/ Since you mentioned running game servers, a service that allows for that kind of traffic (like the four here) would be better You could use Cloudflare Spectrum for game servers, but that's money This one has a free tier you could experiment with that sounds exactly like what you described https://playit.gg/

xB4CKD00R•63d ago

This looks nice Ll test when home Is it possible to forward from my home server to a vps and use its public IP to publish stuff? "hybrid setup where you continue to host them at your location behind your CGNAT but establish a VPN tunnel from your location to a VPS or something similar where you can get a public IP address and then use that as the entry point for your users to hit your server over the VPN." Ah wtf Its basically making a VPN from the vps And connect to it through a client from your home server

DirtyJ•63d ago

that is pretty much what all of those solutions are, either that or a proxy that you connect to

xB4CKD00R•45d ago

ok can you help me take a decision? xD till today i did nothing @DirtyJ @weet hope im not disturbing by pinging ayo i got a vps running ubuntu 20.04 and i successfully made a wireguard tunnel its working great and fast speed i can't manage to expose the stuff i host from the pc at home ?

DirtyJ•45d ago

Any application you want to be publicly accessible like that will need to either be forwarded (which you can't do given the network limitations), proxied, or tunneled out of there

xB4CKD00R•45d ago

LOL u can open ports on amazon vps for free there is no router behind you just open the firewall on the vps page and im doing it but for some reason its not working

DirtyJ•45d ago

Oh if you're referring to a different issue, probably time to make a new thread. We were looking at your fun natting in here

xB4CKD00R•45d ago

im doing a small test Trying to espose the minecraft server hosted on my home server which is connected to the wireguard VPN hosted by my vps

w33t•45d ago

:PES_HuhWtf:

xB4CKD00R•44d ago

doesn't make sense to you? i find it quite simple expose to the internet the server hosted on the client connected to the vpn

DirtyJ•44d ago

so what's your question lol

xB4CKD00R•44d ago

how do i allow the traffic coming from the vpn client to go over to the internet basically the vps has to send the traffic from the pc connected to its vpn to the open internet using the vps public ip

DirtyJ•44d ago

forward the port to the client's VPN IP on the VPS

xB4CKD00R•44d ago

i did ayyyyyyy i did it! 😄 PostUp = iptables -t nat -A PREROUTING -p tcp --dport 25565 -j DNAT --to-destination 10.155.88.2:25565 PostUp = iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE PostDown = iptables -t nat -D PREROUTING -p tcp --dport 25565 -j DNAT --to-destination 10.155.88.2:25565 PostDown = iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE this was missing

w33t•44d ago

It makes perfect sense, I just don't get the point

xB4CKD00R•44d ago

I was missing IP tables rules

w33t•44d ago

I... I see that lol :Facepalm:
