You have an infinite loop going on

Does Cloudflare's dash show preconnect stats anywhere?

Does anyone know how expensive Cloudflare Magic Transit is?

especially if you expect more than 2-3 attacks a year

Hi how can i check the completion time of a workers code

I have an API I want to access from a cloudflare worker. But I need to do so from a dedicated IP that the API vendor can whitelist. Is there a product that can help me do that?

Depends on what you are looking for. If you want to run all external traffic then using a VPN solution like wireguard or openvpn would work. Just have to do stuff with routing

<@256198136106582026> Within ProxMox to setup a VPN connection for each VM, would they each need their own IP address too? I'm unsure how to facilitate that.

Like public IP address? Each VM would get a private address when you add it to the VPN

Right, so... on the LOCAL network, of course, they'll get a private ip address, but from there, within the VM, they can extrapolate my public IP address which could be dangerous for me. If using a VPN connection from my linode server to my VM, I would need a separate public IP address for them, no? Or they all use the same ip? In which case, how would I manage port management, so one VM on an IP address can host port 80 while another one can as well and they don't collide?

Unless you have web apps that can be exploited running then they won't be able to get your actual public IP address. The traffic would go VPS <- VPN -> VM. If you want multiple servers to use port 80, assuming it is HTTP you can run something like nginx  on the VPS which will check the host header and route to the backend as configured.

To be honest I'm wanting more of a hands off approach to this. I'm selling off these VPS servers and its the customer's responsibility to manage them and their system settings. However, I want them all to be able to use whatever ports they want and for forwarded traffic to work appropriately. Getting my hands dirty with their configuration is a no-go. So I'm thinking, if they want the VPS just for a normal VPS, nothing crazy, then they can use cloudflare tunnel on their own VPS for whatever app they want to setup, and that should work for them. But if they want to host a VPS with several apps and several ports, they may need a dedicated IP to do so, and if that's the case then I'll have to set it up through the VPN itself.

The question is, should I set the VPN up on the guest or on the Host? I'm thinking the host, but then I'm unsure how to manage that within proxmox.

It would be on the proxmox host. You'd have to use the shell of proxmox to install and configure the VPN for it.

Ok, I think it's coming together now. 

So, if said customer wants to host a website or whatnot, then they'll need to use cloudflare tunnel on their own account, with their own domain, inside their Guest VPS VM. The traffic would be routed through my VPN anyway, so they won't see any difference here. Everyone will share the same IP address  for the "main vpn". If they for some reason will need a dedicated IP address, then they'll have to pay for their dedicated IP address at cost from linode. I will setup the vpn tunnel using wireguard or something, and connect it in the host for them. Then they'll have their own ip address from there.

Sounds perfect, so then my next question is, can you have more than one tunnel on a VPS?

Yeah. I typically have two tunnels on a server

ok, fantastic. Now, which IP address for cloudflare should I give the customer to use? Their local IP on my own network, or the VPN ip?

Like if they wanted to make a DNS record? That would be the public IP

hmmm, maybe so, yes. So it would be the VPN IP address

Hey folks, I have a project and my

```js
const API_TOKEN = 'YOUR_CLOUDFLARE_API_TOKEN';
const ACCOUNT_ID = 'YOUR_ACCOUNT_ID';
const NAMESPACE_ID = 'YOUR_NAMESPACE_ID';
const KV_PAIR = {
  key: 'your_key',
  value: 'your_value'
};

async function writeKVPair() {
  const urlEscapedKey = encodeURIComponent(KV_PAIR.key);
  const response = await fetch(`https://api.cloudflare.com/client/v4/accounts/${ACCOUNT_ID}/storage/kv/namespaces/${NAMESPACE_ID}/values/${urlEscapedKey}`, {
    method: 'PUT',
    headers: {
      'Authorization': `Bearer ${API_TOKEN}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(KV_PAIR)
  });

  if (response.ok) {
    console.log('Key-value pair written successfully!');
  } else {
    console.error('Failed to write key-value pair:', await response.text());
  }
}

writeKVPair();
```
example:

oh you're right lol, don't trust ChatGPT. It still works, you can change the Content-type though.
Keep in mind too the Key pair in that example become part of the body fully. If you just want a value, just include the value

i can do adjust what I want, im getting same issue. my full code here:

```js

async function saveToCloudflareKV(key, value){
  
  const accountId = await Env.get('CLOUDFLARE_ACCOUNT_ID')
  const namespaceId = await Env.get('CLOUDFLARE_KV_NAMESPACE_ID')
  const apiKey = await Env.get('CLOUDFLARE_API_KEY')
  
    const apiUrl = `https://api.cloudflare.com/client/v4/accounts/${accountId}/storage/kv/namespaces/${namespaceId}/values/${key}`;
  
    const headers = {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${apiKey}`,
    };
  
    const body = JSON.stringify({
      key,
      value,
    });
  
    try {
      const response = await fetch(apiUrl, {
        method: 'PUT',
        headers,
        body
      });
  
      if (!response.ok) {
        console.log(await response.text())
        throw new Error(`Failed to save KV pair. Status: ${response.status}`);
      }
  
      console.log('KV pair saved successfully');
    } catch (error) {
      console.error('Error saving KV pair:', error.message);
    }
}

  await saveToCloudflareKV('test', 'test')

```

and the error is? I'd log the apiUrl as well, and you might want to use encodeURIComponent on the url key to ensure it's always valid in the url

{"success":false,"errors":[{"code":10000,"message":"PUT method not allowed for the api_token authentication scheme"}]}

Error saving KV pair: Failed to save KV pair. Status: 405

but nowhere i am seeing encodeURIComponent in the docs?

> Use URL-encoding to use special characters (for example, :, !, %) in the key name.

What's the apiURL? I think one of your variables like accountId or namespace Id aren't right/aren't being passed in right

I don't know what you're passing into it, I was just saying
> you might want to use encodeURIComponent on the url key to ensure it's always valid in the url

i can see that all 3 envs have been successfully retrieved

```js
async function saveToCloudflareKV(key, value){
  
  const accountId = await Env.get('CLOUDFLARE_ACCOUNT_ID')
  const namespaceId = await Env.get('CLOUDFLARE_KV_NAMESPACE_ID')
  const apiKey = await Env.get('CLOUDFLARE_API_KEY')

  const KV_PAIR = {
    key: 'your_key',
    value: 'your_value'
  }

  const urlEscapedKey = encodeURIComponent(KV_PAIR.key)
  
    const apiUrl = `https://api.cloudflare.com/client/v4/accounts/${accountId}/storage/kv/namespaces/${namespaceId}/values/${urlEscapedKey}`;
  
    const headers = {
      'Authorization': `Bearer ${apiKey}`,
      'Content-Type': 'application/json',
    };
  
    const body = JSON.stringify(KV_PAIR);
  
    try {
      const response = await fetch(apiUrl, {
        method: 'PUT',
        headers,
        body
      });
  
      if (!response.ok) {
        console.log(await response.text())
        throw new Error(`Failed to save KV pair. Status: ${response.status}`);
      }
  
      console.log('KV pair saved successfully');
    } catch (error) {
      console.error('Error saving KV pair:', error.message);
    }
}
```

still same issue ._.

That code works fine for me in node if I hardcode the values instead of use env

Make sure your API Token has the right perms too, needs KV: Write

error was in front of the pc,, submitted the kv namespace name instead of id... happy new year i would say! thanks!

do you know how to save a video into KV or something like images? only know the R2 way of it.,

still failing

You can have a record for `subdomain.domain.com` without having a record for `domain.com`.  What makes if you make a new proxied AAAA record for `@` with a value of `100::`. Does the redirect work then?

but  I dont have ip address 6 only ipv4 and its dynamic since its my home ISP

If you want to redirect then you just need a dummy record like with `100::` as the request needs to hit Cloudflare so it can be redirected

ok did that now going to domain.com

What does your redirect rule look like? Are you using bulk redirects?

cleanshot-2024-01-09-at-00-03-572x

Bulk Redirects are the recommended way for static redirects. Unless you have specific parts of the path you want to redirect then I would use them

mm I dont see where is the bulk redirect section

https://developers.cloudflare.com/rules/url-forwarding/bulk-redirects/create-dashboard/

okay now it works, why with Simple redirect did't work?

The URI Full is more picky then bulk redirect. If you wanted to use a redirect rule then hostname would probabaly be better but bulk redirect are better for static redirects
