How do I setup a reverse proxy on Cloudflare?

Someone · 2024-04-16T02:35:42.049Z

Basically, I'm trying to convert http://149.56.67.129:25585 into https://svexpanded.com/ How would I do this?

depending on the type of website you could use an nginx reverse proxy:

server {
  listen 80 default_server;
  client_max_body_size 100M;
  server_name <your domain (optional)>;
  
  location / {
    proxy_pass http://localhost:3000;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
}

server {
  listen 80 default_server;
  client_max_body_size 100M;
  server_name <your domain (optional)>;
  
  location / {
    proxy_pass http://localhost:3000;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
}

server {
  listen 80 default_server;
  client_max_body_size 100M;
  server_name <your domain (optional)>;
  
  location / {
    proxy_pass http://localhost:3000;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
}

server {
  listen 80 default_server;
  client_max_body_size 100M;
  server_name <your domain (optional)>;
  
  location / {
    proxy_pass http://localhost:3000;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
  }
}

Or workers:

fetch(request) {
    const url = new URL(request.url)
    url.host = "149.56.67.129:25585"
    return fetch(url, request)
}

fetch(request) {
    const url = new URL(request.url)
    url.host = "149.56.67.129:25585"
    return fetch(url, request)
}

fetch(request) {
    const url = new URL(request.url)
    url.host = "149.56.67.129:25585"
    return fetch(url, request)
}

fetch(request) {
    const url = new URL(request.url)
    url.host = "149.56.67.129:25585"
    return fetch(url, request)
}

Is this possible going through just Cloudflare? I do not have the resources currently to setup a VPS and nginx reverse proxy

you could use cf workers

SomeoneOP•4/16/24, 5:38 PM

I'll test out this:

fetch(request) {
    const url = new URL(request.url)
    url.host = "149.56.67.129:25585"
    return fetch(url, request)
}

fetch(request) {
    const url = new URL(request.url)
    url.host = "149.56.67.129:25585"
    return fetch(url, request)
}

fetch(request) {
    const url = new URL(request.url)
    url.host = "149.56.67.129:25585"
    return fetch(url, request)
}

fetch(request) {
    const url = new URL(request.url)
    url.host = "149.56.67.129:25585"
    return fetch(url, request)
}

Could you expand on that a bit more? Not quite sure what you mean hahaha

Do you have access to the domain name you bought

R

RyanKnack•4/17/24, 12:25 AM

Add that domain name to CloudFlare

Already added, yes

R

RyanKnack•4/17/24, 1:40 AM

Do you have the DNS records set up for proxying?

R

RyanKnack•4/17/24, 1:42 AM

Type: A
Name: @
Target: 149.56.67.129

S

SomeoneOP•4/17/24, 1:42 AM

Yes, that has been added

R

RyanKnack•4/17/24, 1:42 AM

So now you need to overwrite the port from 80 (HTTP)/443 (HTTPS) to your specified port (25585)

R

RyanKnack•4/17/24, 1:43 AM

Under rules > origin rules > new

R

RyanKnack•4/17/24, 1:46 AM

Should be "all Incoming requests" then "overwrite to 25585"

S

SomeoneOP•4/17/24, 4:30 AM

S

SomeoneOP•4/17/24, 4:30 AM

i needed to proxy the A record

R

RyanKnack•4/17/24, 4:30 AM

I think you may need to configure the DNS on your server side as well

R

RyanKnack•4/17/24, 4:30 AM

Can I see your DNS entries

S

SomeoneOP•4/17/24, 4:30 AM

I had it on DNS only, Proxied works :D

works on my phone though

R

Not sure how to bypass browser cache but on windows it is Ctrl + F5

S

SomeoneOP•4/17/24, 4:32 AM

Safari is dumb, even when I empty caches it still persists lol

R

RyanKnack•4/17/24, 4:32 AM

It's a HTML page for now right?

S

SomeoneOP•4/17/24, 4:32 AM

Yep!

R

RyanKnack•4/17/24, 4:32 AM

CF doesn't cache HTML by default so it should just be your browser cache

R

RyanKnack•4/17/24, 4:33 AM

But if it works on your other device and on my end I do see the page you wanted

R

RyanKnack•4/17/24, 4:33 AM

So it works

R

RyanKnack•4/17/24, 4:33 AM

Oh try incognito

S

SomeoneOP•4/17/24, 4:34 AM

SomeoneOP•4/17/24, 4:34 AM

Thank you so much for your help!

No probs!

S

SomeoneOP•4/17/24, 4:37 AM

Should I just close this channel or how does it work here?

I think you can just leave it here. The answers are all indexed to the web. Mark it as solved would be helpful
