PIX Port Forwarding

[vlad1slav]

I have a static IP assigned by my ADSL provider.

My topology is as follows:

Internet --> ADSL Modem/Router --> Cisco PIX 501 --> Local Area Network (192.168.1.X)

ADSL Modem Interfaces
Outside: 213.1XX.XX.XXX
Inside: 192.168.0.1

Cisco PIX 501 Interfaces
Outside: 192.168.0.2
Inside: 192.168.1.1

The ADSL modem is currently configured to forward all traffic directly to the PIX 501 outside interface. What I would like to do is forward all traffic coming in on port 80 to something like 192.168.1.15 (On the Local Area Network) and all traffic on port 21 to 192.168.1.16 (Again on the local area network).

I have spend a couple of days now playing around with various access-list/access-group/static route set-ups, but I’ve yet to crack this puzzle. Can anyone point me in the right direction?

Here is my current config:

Try adding these commands

static (inside, outside) tcp interface 80 192.168.1.15 80 255.255.255.255
static (inside, outside) tcp interface 21 192.168.1.16 21 255.255.255.255
access-list outside_access_in permit tcp any any eq 21

Hi

How you do port forwarding on your router to you PIX?? I have the simmilar topology as yours. But my OWA cannot work maybe because of the router configuration.Please show me what are the few important command need to do port forwarding.


Thanks
