Named pipes connection for SQL

[Xames81]

I have the DNS Server with one server of my LAN with windows server 2012 r2, all clients of opnsense dhcp seems to have this server as default, my question is... when i do a connection on any machine of my LAN throught this configuration on opnsense with this server on dns, is the named pipes connection passing throught OPNSense or is connected directly over my server?

Thanks.
