PIX Configuration

This is the question

I have a 3 public ip addresses the first ip address has a static map to the internal interface of the pix, the other two have static mappings. I am using access list to provice port redirection. I want to redirect port 80 (www) to an inside address, however because the their are static mapping for the three public address i have, it seems i can not do this.

Hi akita29,
Thats correct. If you have static mappings you are effectivly saying all ports outside for that IP are to go to the specified internal IP address. You cannot redirect a particular other port to another machine.

If you post your current configuration we can suggest ways around it for you.

static (inside,outside) tcp interface 80 X.X.X.X 80 netmask 255.255.255.255 0 0
^^^^^ - internal ip address you want port 80 to be redirected to.

The internal host would then be available on 120.33.200.66 :80

Try it, however can not hit the web page.. i will take a look again..

martap

try to do a "clear xlate".

Did the clear xlate, no luck. any other suggestions. question on the netmask i enterd 255.255.255.255 0 0 however should it be 255.255.255.0 0 0 for a class c

btw i did not write it to memory, because if there an error i just need to restart the pix. this should not be an issue?

You are redirecting port 1666 to an internal machine here so you can add additional ports to the list.

I am not sure if you can redirect port 80 on the external interface. I have seen problmens with this before. I would try something like :-

static (inside,outside) tcp interface 81 10.0.7.x 80 netmask 255.255.255.255 0 0
Then try to view the website from outside the network (NOT inside) on http://120.33.200.66:81.
If that works change the '81' in the line above to '80' and try again.

It wont matter that you haven't saved the config.
