TrueNASTorrentingStack

Use macvlans to bind docker containers to a single address.

When torrenting we typically want to hide our real IP address so our ISP doesn't get mad at us. I have a VLAN, set up in pfsense, that routes through wireguard to an AirVPN VPN, thus hiding my real ip address to anything connected to this network. This VLAN is set up as br23 on my TrueNAS. It uses the IP range 192.168.23.1/24.

Back in the TrueNAS Core days, we could easily route FreeBSD Jails through a single interface, in the web UI. We could even use DHCP. TrueNAS Scale does away with Jails and uses docker instead. In docker we can do something similar with macvlans to allow our containers to get a new IP address routing through a given network. Unfortunately we can't get DHCP addresses from our router, everything has to be set to static.

Sadly, as of TrueNAS Scale Electric Eel, and apparently Fangtooth too, this is not possible in the web UI. Which has annoyed a lot of people. This is how I have achieved it, using docker-compose.
