System Backup - os-git-backup - uses Tayga interface to access Github

[IsaacFL]

I recently installed the os-git-backup for system backup. I created a private repository on GitHub and have it working via SSH to GitHub.

I do have the firewall log outgoing port 22 and I notice that it is going out via the Tayga interface. It works, but that seems odd as the Opnsense router has working IPv4?
