I'm not sure what the OS lets us do, but if it lets us pick the IP and port I think that would work; I don't think you need another tcp: since we already know which protocol we're using. > > ``` > > Is it an available solution?

I assume there's a wayto get the host network stack to prefer the 10GbE interface. Or to use separate subnets; rememember that each interface can have multiple IP addresses.
