Send udp message on eth1

Hi whats the best way to send a udp message on eth1 interface?
I think the node red is running on eth0. There doesnt seem to be a way to chose that in the udp send node.??

the udp node will just send to an address - it's up to you and your routing table as to which adapter is used to route to that address. On a linux box command prompt type route and it should show you how it is configured.

thanks for pointing me in right direction
