It is quite useful to add information on the two interfaces to the hosts file in the way shown below, so we have handy names for them, too:
191.72.1.1 vlager vlager.vbrew.com
191.72.1.1 vlager-if1
191.72.2.1 vlager-if2
The sequence of commands to set up the two interfaces is then:
# ifconfig eth0 vlager-if1
# ifconfig eth1 vlager-if2
# route add brew-net
# route add wine-net
