More than one interface in my PC

Just for my own knowledge, if I have a PC with two interfaces the
ethernet one and a wireless one, and I configure both of them with
DHCP, then when I send a packet is there any kind of load balancing ?
or the gateway is just configured in the first interface that is
activated, so is only used one of the interfaces ?

Thanks a lot!

I think the kernel will just use whichever entry comes first in the routing
table-- run 'route' to see it. But I think you can do load-balancing too;
see the Advanced Routing and Traffic Control HOWTO.

Unless you do more advanced routing (per Adv-Routing HOWTO), any packet
would typically take the first route that matches in the routing table
(/sbin/route -n). So if both interfaces are on the same network, only one
of the interfaces would actually be used.
