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?

Did you enable DNS64? Then it's expected behavior. IPv6 is generally preferred over IPv4 and it doesn't matter whether the destination address is a "native" IPv6 address or an address synthesized by DNS64.

I do have DNS64 enabled but was just surprised that the router itself was using NAT64 internally. It seems to work, was just worried I had misconfigured it.

If you don't want OPNsense itself to use NAT64, then you need to configure a DNS server without DNS64 in System / Settings/ General.
