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.

                                                          ^^^^^ - internal ip address you want port 80 to be redirected to.

The internal host would then be available on :80

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

try to do a "clear xlate".
akita29Author Commented:
Did the clear xlate, no luck.  any other suggestions.  question on the netmask i enterd 0 0  however should it be 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?
> static (inside,outside) tcp interface 1666 1666 netmask 0 0
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 0 0
Then try to view the website from outside the network (NOT inside) on
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.
clear xlate
static (inside,outside) tcp interface 80 80 netmask
access-list 1 permit tcp any interface outside eq 80
access-group 1 in interface outside  <== always re-apply the acl


damn, I missed the access-list part...

lrmoore is right, you also need to add the access-lists to allow port 80 in.

Thanks guys or girls.  Lrmoore you have helped in that past another good job.  martap thank you also, you started the ball rolling, both of you ROCK...
