As long as your DNS records are proxied then the CDN will be enabled for it

you mean add cloudflare's IP to my DNS settings?

BlaBla (Please tag or reply)OP•8/21/23, 7:35 PM

but where to store the website?

Picolé•8/21/23, 7:36 PM

can cloudflare tunnels be used for RTSP streaming? Been trying but wont work at all

BBlaBla (Please tag or reply)but where to store the website?

Cyb3r-Jak3•8/21/23, 7:41 PM

If you site is static then you can use pages. Otherwise you have it on a origin server with the IP being in Cloudflare DNS and being proxied

Cyb3r-Jak3•8/21/23, 7:42 PM

I forget RTSP but if it uses TCP and not HTTP then you’ll need to have cloudflared on the clients as well

what is a static website? One that does not fetch data from db to render pages? Yes it is that.

BlaBla (Please tag or reply)OP•8/21/23, 7:43 PM

Do I need to buy the domain from cloudflare?

At static site is something that is just HTML doesn’t use something like go or python to render content.

Cyb3r-Jak3•8/21/23, 7:44 PM

You do not need to buy a domain from Cloudflare but you need the nameservers of the domain to point to your assigned nameservers

I think there is some available in Instant Logs, but dont quote me on that

Logpush also has them

Cyb3r-Jak3•8/21/23, 9:34 PM

I believe ngrok proxies TCP without client side software. Cloudflared requires client software if you use anything other than HTTPS

Cyb3r-Jak3•8/21/23, 9:34 PM

?tunnel-tcp

Flare•8/21/23, 9:34 PM

Cloudflare Tunnels use Cloudflare's proxy, which only supports proxying HTTP Traffic. If you want to use non-http applications over your tunnel, Cloudflare has a few other options:

For a few specific protocols such as SSH, RDP, and SMB, Cloudflare has guides for them here:
https://developers.cloudflare.com/cloudflare-one/applications/non-http/

For Arbitrary TCP like Minecraft, MySQL, and any other tcp application, Cloudflare has a guide here: https://developers.cloudflare.com/cloudflare-one/applications/non-http/arbitrary-tcp/

For Arbitrary UDP like Minecraft Bedrock, SMTP, and any other udp application, you will need to use Private Networking with WARP: https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/private-net/connect-private-networks/

Please note for all of these except SSH and VNC which can be browser-rendered, you will either need to use cloudflared (Cloudflare's tunnel daemon) on the client machine running in the background or Private Networking with WARP, and have WARP installed on the client machine logged into your Zero Trust Team.

I installed it on both ends, still nothing sadly

How are you accessing it from the client?

both pcs logged into cloudflared same account

Cyb3r-Jak3•8/21/23, 9:38 PM

From the client you are doing

cloudflared tunnel --hostname tcp.site.com --url tcp://localhost:7870

cloudflared tunnel --hostname tcp.site.com --url tcp://localhost:7870

then pointing the RTSP client to

localhost:7870

skoogeer•8/21/23, 10:29 PM

No, if you create a Domain Lockdown record, then we will not deliver any email for your domain except as you authorize it in your lockdown record.

skoogeer•8/21/23, 10:30 PM

This no longer works because you must have a Domain Lockdown record in place before you can send email using our API on Workers.

skoogeer•8/21/23, 10:31 PM

@nora This is not true. If you set up a Domain Lockdown record for your domain, then we will not deliver email for your domain except as you specifically authorize in the DNS.

Cchientrm.com I'm not sure, $80 then they can spoof but Idk how could they spoof DKIM.

skoogeer•8/21/23, 10:33 PM

To be abundantly clear, if you create a Domain Lockdown record, then even someone paying MailChannels $1M/mo cannot send email on behalf of your domain.

Unsmart•8/21/23, 10:45 PM

so $2M/mo is the lucky number /s

James•8/21/23, 10:54 PM

How would someone enforce Domain Lockdown when they don't use Workers? That's entirely related to the

cf-worker

cf-worker

header... no? How do I ensure only I can send from my domain, and not any of your other paying customers, outside of Workers?

James•8/21/23, 10:54 PM

All of the docs I've seen at least are explicitly talking about

cf-worker

cf-worker

. If there's something I'm missing, please let me know

Cchientrm.com I got MailChannels lockdown + SPF + DKIM + DMARC setup already.

DarkDeviL•8/21/23, 10:57 PM

Depending on your "trust", re. e.g. the messages above, you can also kill the SPF in various different ways (deleting the SPF record, removing "include:relay.mailchannels.net", ... or similar), and attempt that way to lean only on DKIM authentication, if you're 100% sure that DKIM is set up and working properly, which your DMARC reports can eventually assist with (over time).

While I am a fan of as strict security policies as possible, including e.g. having a DMARC reject, and SPF "-all" (e.g. DASH all) policy, setting SPF alone to "v=spf1 -all" as an attempt to lean on DKIM authentication alone, may be able to trigger some spam filters, believing that the "v=spf1 -all" means "this domain never sends mails".

That part should be solvable, by having any (apparent valid) part between "v=spf1" and "-all" though.

Final result, regardless what you do or attempt, will always depend on the individual receiving mail server / destination though.

James•8/21/23, 10:57 PM

But it does still work if someone just gives you $80 and uses your SMTP relay, no?

James•8/21/23, 10:59 PM

With Workers, yes

James•8/21/23, 10:59 PM

I'm talking outside of Workers entirely

James•8/21/23, 10:59 PM

How can I setup a Domain Lockdown record that lets only me send using the SMTP relay, and no on else? Not in Workers.

DarkDeviL•8/21/23, 11:00 PM

Isn't that on https://support.mailchannels.com/hc/en-us/articles/16918954360845-Secure-your-domain-name-against-spoofing-with-Domain-Lockdown- ?

James•8/21/23, 11:01 PM

Oh I see, there's

auth

auth

and

senderid

senderid

options instead of

cfid

cfid

. Okay this is good.

James•8/21/23, 11:01 PM

Now they need to enforce this for all customers.

James•8/21/23, 11:01 PM

And then, I'll be happy recommending MailChannels

This sounds what @ttul said abvove that it is (now being)?

DDarkDeviL This sounds what @ttul said abvove that it is (now being)?

James•8/21/23, 11:02 PM

I mean, enforce sender verification in general. Don't allow any email to be sent without this (or something) set. So actually protect their large customers like

boston.gov

boston.gov

DarkDeviL•8/21/23, 11:04 PM

Could be me, but doesn't general-discussions sound like it's in effect already?
