Limit deluge internet access to specific network interface

[delo]

Hey, I am running deluged and deluge-web on my Linux Mint seedbox.
I am using a VPN, and restricting deluged to only use the network device the VPN creates.
For this to work, in my experience, I also have to provide the IP address this network device has to deluge.

Problem is, everytime the vpn provider changes this IP address, deluge stops working, and I have to manually update the IP address in the deluge webinterface.

For my use case, restricting deluge to a network interface would suffice for it to never leak traffic into the clearnet, no matter the specific IP address.
Is this possible? How would I do that? And if not: Does anyone know how to update the IP address automatically in order for deluge to never stop working?

Cheers,
delo

There are scripts built into certain Deluge Docker containers, such as binhex's, that handle this, which you can then use the thin-client to connect to (as Docker does not natively provide the GUI), or you can write your own script to do so if you have coding experience.

"listen_interface": "", value in core.conf would be the relevant setting.

Since Deluge does not natively support third party VPN's then, you could also use something that supports split-tunneling that automatically captures the traffic and wouldn't require configuring Deluge.
