SQL Server Developer edition on Ubuntu: Allowing remote connections

Question

I've got SQL Server 2019 Developer Edition up and running on my Linux VM. I'd like to remotely connect to that SQL Server instance from my Windows development PC.

All of the information I can find online basically revolves around configuring a Windows based SQL Server to allow remote connections and then connecting into it from Linux, which I need the opposite of. I'd like to write some Python code on my development machine to interact with this db.

I use Dbeaver as an interface tool, and I've ran the following:

EXEC sp_configure 'remote access', 0;

and

RECONFIGURE;

But I'm really not sure what else to do from here, I've never configured anything like this before.

When looking at netstat -tulpn I can see SQL Server listening on 127.0.0.1:1434 along with some other ports, as well as 0.0.0.0 and even :::1433.

But utilizing sqlcmd -S my_server_ip,1434 -Usa on Windows is running into:

Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : Login timeout expired.
Sqlcmd: Error: Microsoft ODBC Driver 17 for SQL Server : A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online..

Any tips on setting this up? Possibly a firewall issue, or are there configuration steps I'm not thinking of?
