Need to add route in CISCO 3600 router

[Guest_imported]

(Newbie)
This is difficult to explain but I will do my best.
I need to route traffic coming from an NTserver to a linux server. My problem is there is a PIX firewall that is recieving the traffic from the NT server instead of the Linux BOX. I will try to draw an ASCII diagram to explain better.
INTERNET
| |
LINUX PIX
| |
--------
|
(1)Cisco 3600 (WAN)
|
(2)Cisco 3600 (WAN)
|
NTSERVER

INTERNET 207.248.143.35
LINUX external 207.248.143.40
LINUX internal 172.16.9.240
(1)CISCO 3600 (WAN) 172.16.9.254
NT SERVER 172.16.10.125

My question is how can I get the (1)Cisco router to send all traffic coming from the NT server to Linux server instead of the Pix firewall? I'm new to cisco routers
if you can be as detailed as possible, Thank you in advance.

Try to use static routes to hard code the path to the NT box.

ip route NT address NT mask Next hop (linux box)

You can code the route to route one specific address or a range of IPs

If I'm not mistaken, you may need to enable static routes on the Linux box to point to the internet and back to the Cisco.

I was thinking the same about the static route , however I think just maybe a ip-helper
address might be needed on the ethernets !!!

The IP helper might be needed depending on what RAID wants pass for traffic. He wont need it for HTTP, port 80 traffic.. just broadcast based stuff like WINS, DNS, TFTP, DHCP ( BOOTP) and the like..there are 10 protocols passed if I remember correctly.

The linux box doesnt care about most NT stuff.. but it can care about SMB traffic and it can emulate an NT server pretty well for browsing and shares.

You would need to do policy based routing. That would enable you to route based on the source address.
