Anyway to proxy a 80 port web server?

I have a web server running on a 80 port and was wondering if there's anyway to get that proxied so it hides my backend IP. Does anyone have any ideas here?

Proxying directly on Cloudflare DNS seems to break it entirely... gives me the error in the screenshot.

SomeoneOP•9/3/24, 8:31 PM

If I have it set as not proxied and DNS only, it works fine.

So 80/http only, no https? Under SSL/TLS -> Overview change your SSL to Off if that's the only website on the domain, or you can use a Configuration Rule with Hostname eq to override it

Chaika•9/3/24, 8:49 PM

If you're not doing https/443 because certs are annoying to setup or something like that, you could use Cloudflare Tunnels, simple connector you install on the same server/network, and then
User -> Encrypted -> CF -> Encrypted -> Tunnel -> unencrypted but LAN or same machine -> origin host, to avoid any security issues

It does have SSL if that changes anything

SomeoneOP•9/3/24, 8:50 PM

I suppose 443 port too then

Chaika•9/3/24, 8:51 PM

It changes a lot yea, should be 80 & 443 then if properly setup. Does it work without proxy?

SomeoneOP•9/3/24, 8:51 PM

Yep! Works fine without proxy

SomeoneOP•9/3/24, 8:51 PM

Just want to hide that backend IP, this is the final obstacle before everything is hidden hahaha

Chaika•9/3/24, 8:51 PM

Works fine with https or http without proxy?

CChaika Works fine with https or http without proxy?

SomeoneOP•9/3/24, 8:52 PM

With https, yeah

SomeoneOP•9/3/24, 8:52 PM

and http, but directs to https

Chaika•9/3/24, 8:52 PM

If you go to SSL/TLS -> Overview, what's your setting?

SomeoneOP•9/3/24, 8:52 PM

Flexible

Chaika•9/3/24, 8:52 PM

go to Full (Strict)

SomeoneOP•9/3/24, 8:52 PM

Awesome, that's done

Chaika•9/3/24, 8:52 PM

Flexible is not something that should ever be used, it's user -> https -> cf -> http (plaintext!!) -> origin

Chaika•9/3/24, 8:53 PM

looks like you unproxied it?

SomeoneOP•9/3/24, 8:53 PM

annnnd it seems like it's working now!

SomeoneOP•9/3/24, 8:53 PM

hahaha thank you so much!

SSomeone annnnd it seems like it's working now!

Chaika•9/3/24, 8:54 PM

I think you're just behind dns cache

SomeoneOP•9/3/24, 8:54 PM

is it not working for you?

SomeoneOP•9/3/24, 8:55 PM

ah rip it's not on my alternate computer

SomeoneOP•9/3/24, 8:55 PM

Chaika•9/3/24, 8:55 PM

yup, run a trace (account level option -> trace) and see what it hits with the url https://bans.nekobox.es/https://bans.nekobox.es/

Chaika•9/3/24, 8:55 PM

Magic Link: https://dash.cloudflare.com/?to=/:account/trace/search

SomeoneOP•9/3/24, 8:56 PM

Send a screenshot here?

SomeoneOP•9/3/24, 8:56 PM

Chaika•9/3/24, 8:57 PM

yup, what's that origin rule?

SomeoneOP•9/3/24, 8:58 PM

SomeoneOP•9/3/24, 8:58 PM

basically a reverse proxy

Chaika•9/3/24, 8:58 PM

ok so that's making all requests for all hostnames on your zone/website go user -> http/443 -> cf -> https/25574

SomeoneOP•9/3/24, 8:58 PM

Chaika•9/3/24, 8:58 PM

what were you trying to accomplish with that?

Chaika•9/3/24, 8:58 PM

Is it something that should be more scoped to a specific subdomain, orr

SomeoneOP•9/3/24, 8:59 PM

redirect linking.nekobox.es to the web server with 25574

Chaika•9/3/24, 8:59 PM

click "Custom Filter Expression" "Hostname" "eq" "linking.nekobox.es"

Chaika•9/3/24, 9:00 PM

side note: we may have broke that subdomain when we switched ssl/tls, you should really have proper ssl/tls at your origin though. If you need an ssl cert, CF offers 15 year long ones under SSL/TLS -> Origin Server, or Cloudflare Tunnels are really easy secure setup

Zach•9/3/24, 9:00 PM

just so u guys know u have issues w the linking subdomain too

Chaika•9/3/24, 9:00 PM

yea that's what I just said above lol, although if it was working just because of Flexible that's not really working/zero security

CChaika click "Custom Filter Expression" "Hostname" "eq" "linking.nekobox.es"

SomeoneOP•9/3/24, 9:10 PM

What does eqeq mean here?

SomeoneOP•9/3/24, 9:10 PM

equal?

Chaika•9/3/24, 9:10 PM

equals

SomeoneOP•9/3/24, 9:10 PM

amazing, just did that

Chaika•9/3/24, 9:10 PM

oh sorry yea the dashboard doesn't say that only the underlying expression language

SomeoneOP•9/3/24, 9:11 PM

any other steps i should do regarding the DNS settings?

SomeoneOP•9/3/24, 9:11 PM

keep linkinglinking as proxied on DNS?

Chaika•9/3/24, 9:13 PM

if you want to hide both yea both should be proxied, see Anyway to proxy a 80 port web server? about fixing its ssl tho

SomeoneOP•9/3/24, 9:17 PM

Using the origin server, could you walk me through how to do that?

SomeoneOP•9/3/24, 9:17 PM

either one works, not too advanced in the DNS stuff yet hahaha
