Connectiong to mssql over tunnel

Zero Trust Cloudflare Tunnel

What is the name of the domain?

prefer not saying

What is the issue you’re encountering

i’m trying to connect to mssql over a tunnel but it’s not working. i’ve set it up as a tcp tunnel ponting to localhost:1433 (not real port). it works when connecting from outside using the server’s ip, but not over tunnel. from inside the server i can connect to localhost,1433 so the port is working my firewall rules currently only allows inbound connections from my ip, but AFAIK the tunnel is an outbound one. the tunnel shows as healthy when i try to see the connector’s live logs, nothing shows up dns resolves to cloudflare

What steps have you taken to resolve the issue?

set server firewall (not the provider’s) to allow everything: no change
set the dns reccord to not proxy: no change

Meaning, no firewall running, otherwise port is open and MSSQL server responds over it for a remote connection?

Any IP allowlisted or not under MSSQL server to “remote connect”? :thinking:

Directly to the server, or via e.g. PHP code or some other programming language, using the “localhost and port” for hostname/IP? :thinking:

If you’d want to connect from your client, or as a client, then the clients who have or need to access a service running as a tunnel, in your case MSSQL, are advised and should use the command as cloudflared access tcp --hostname sql.example.com --url localhost:12345.

Are ports 80 and 443 open as well?

Are you using this way, or rather WARP? :thinking:
