Hello Network Guys,

I have problem with establishing connection from winxpPC to win2k3PC.
In winxp machine I have two nics(lets one names WAN second LAN). When
I enabling LAN nic my internet connection from WAN failed.
WAN nic gets IP from router, but LAN nic has static IP defined by me.
What would be a reason of that break?

p.s. Please don't ask me why I have such network architecture, it's
for testing purpose

Thanks in advance,

Bartolo
 
to clarify :)
through LAN I want to make connection with win2k3 from winxp

It's probably in the routing. Your WAN traffic goes through the
Default Gateway. Perhaps you defined a default gateway on your LAN
card that is taking precidence. With your configuration, you probably
should not specify a default gateway on your LAN port. From a command
prompt, enter the command:
route print
Look for line(s) that look like
destinantion: 0.0.0.0 mask: 0.0.0.0.
This is your default route. If more than one line like this exists,
the one with the lower "metric" column will prevail. The goal is to
send the default route through your WAN NIC and not your LAN NIC.

HTH,
John

The two NICs must have IP addresses in different subnets. For
example, if WAN get an address in the 192.168.0.x/255.255.255.0
subnet, assign an address in a different subnet, such as
192.168.2.1/255.255.255.0 to LAN.
