network problem

[Guest]

My pc (win XP pro SP2) has Ethernet PCI card with 2 NICs. I connect between
them crossover cable. Both channels have static IP address (192.168.1.1 and
192.168.1.2) and mask 255.255.255.0 and default metric 9999. After this I add
2 rows to routing table to verify that packet are going through external
loopback and not via internal (software) loopback:
Dest Gateway metric
192.168.1.1 192.168.1.2 1
192.168.1.2 192.168.1.1 1
and try ping to 192.168.1.1 or 192.168.1.2 but both pings fail.

The same configuration on the same PC but with Win2000 SP4 works perfect
(both pings are pass).

To solve this problem I tried:
1. Turn off win firewall
2. Turn on "allow incoming echo request"
3. Registry key value of IPEnableRouter changed to 1

Is there something else I should do?

Thanks in advance!

it is not recommended to have two NICs using the same IP subnet in a XP computer. Try this, disable 192.168.1.2, can you ping 192.168.1.1?

This PC is used as automatic test equipment for some product. Before product
testing I need to verify that the Test equipment is OK. Procedure that I
described is for self test of the equipment (to check network card and the
cable).
Therefore disabling of one channel doesn't help me.
