2 IPs 1 NIC ... define src address when going to certain h..

I have a system that has two IPs assigned to one NIC (IP1,
IP2). What I want to setup is when the system wants to
talk to a certain host (call it host B), I want it to use
IP2. The system uses IP1 as it's primary IP, and by
primary I mean when you do a route print, it is the one in
the interface column. This is possible in Linux with
subinterfaces, but I can do it in Windows. I know that I
could add a second card, but I don't have the PCI slots
available.

Hopefully this will better show what I want to do:

C:\Documents and Settings\Administrator>ipconfig

Sorry but I hit return accidently.

here is what i wanted to write before:


C:\Documents and Settings\Administrator>netstat -ar

Network Destination Netmask Gateway Interface Metric
0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.10 30
192.168.1.10 255.255.255.255 127.0.0.1 127.0.0.1 30
192.168.1.11 255.255.255.255 127.0.0.1 127.0.0.1 30

(I want to add a route to 192.168.1.12 but I want the
source IP address when I do to be 192.168.1.11 not
192.168.1.10)
C:\Documents and Settings\Administrator>route add
192.168.1.12 MASK 255.255.255.255 192.168.1.11


C:\Documents and Settings\Administrator>netstat -arn
