Sorry, I wasn't quite clear.
There're two subnets, 172.16.x.x (not 174.xxx, mea culpa) used for shares
and 192.168.x.x on DHCP used for connecting to Internet through a router.

They're physically installed on the same computer, but they're supposed to
be on separate networks.

The whole idea is:
I have two computers, each with two NICs installed. One pair of NICs (one
from each PC) is used for shares, the 172.16.x.x net and the other pair of
NICs connected to the router for Internet connection.
