Cisco PIX 515e Config Question

Posted on 2004-10-29
Last Modified: 2013-11-16
I have a cisco pix 515e that I am having to work on.  I am using the PDM v2.1 because the telnet side has a password that no one knows.  anyways, my problem is that every time I create a rule to map all incoming HTTPS traffic into the firewall to IP it gets changed to a "NULL" rule after I apply it.  I have already setup the Translation rules, and the host/network entry is there.

I'm very frustrated at this because I can't quite figure it out.

any help would be greatly appreciated.

    If you show the config, are there conduits created? If yes, conduits appear as "null" rule in the GUI, but they still work.
    If you can get to the GUI, you can change the telnet password from the config | Admin section...

    The gui wants the old password and will not let me change the telnet password

    Oh, yeah... darn user-friendly interfaces..
    Use the command line feature of the GUI and just change it there:
      passwd <new password>

    Accepted Solution

    If you want to remove these:
      >static (inside,outside) tcp 1 1 netmask 0 0
      >static (inside,outside) tcp 2 2 netmask 0 0

    You can use command line...
     no static (inside,outside) tcp 1 1 netmask
     no static (inside,outside) tcp 2 2 netmask

    This line:
        >access-list PERMIT_IN permit tcp any eq https host eq https
    Should look like this:
        no access-list PERMIT_IN permit tcp any eq https host eq https
        access-list PERMIT_IN permit tcp any host eq https

    the access list line you refered to is the one that it keeps nulling on me... in the gui i'm telling it to point all https traffic inbound to and it kicks it back as null and changes my 192 IP to the 64 IP you see there.  any idea why?

    works perfectly

    It's supposed to be 64.x.x. in the acl because the traffic is initially destined to the public ip, not the private ip.

    Glad to help!
