New to Palo Alto - Append Policy Question

L0 Member

Good day all,

I am new to Palo Alto so this question might actually seem rather trivial.

Most of my peers configure from the GUI and are not very familiar with the Command line.  I am more comfortable with the command line so I am trying to do configurations that way. 

If I want to add a source entity to an existing rulebase security rule do I just recreate the rule with the appended information and then when I commit, it will overwrite the existing rule?

For example

when I do a show rulebase security rules existing_policy

I get the following output:

"existing_policy" {

  from dmz;

  to trust;

  source [ serverA serverB serverC ];

  destination any;

  source-user any;

  application any;

  service any;

  hip-profiles any;

  log-start no;

  log-end yes;

  negate-source no;

  negate-destination no;

  action allow;

}

If I wanted to add ServerD to the source would I do the following (I don't have a test box to test the commands that is why I am coming here):

set rulebase security rules existing_policy from dmz to trust source [ serverA serverB serverC ServerD ] destination any action allow

Any assistance would be appreciated.

Thanks

Wally

Hello Sir,

You are correct, if you apply CLI command  # set rulebase security rules "to NG Sites" destination location3 >>>>>>>>>> This will add the location3 to the destination and leave the current destinations there as well. Please find below example from my test PA firewall:

admin@DADA# show rulebase security rules LAN-ISP

LAN-ISP {

  option {

    disable-server-response-inspection no;

  }

  from Trust-LAN;   >>>>>>>>>>>>>>>>>>>

  to Untrust-ISP;  >>>>>>>>>>>>>>>>>>>>

  source [ any 1.1.1.1/32];

  destination any;

  source-user any;

  category any;

  application any;

  service any;

  hip-profiles any;

  action allow;

  log-start no;

  log-end yes;

  negate-source no;

  negate-destination no;

  log-setting SYSLOG-ALL;

}

admin@DADA# show rulebase security rules LAN-ISP

LAN-ISP {

  option {

  }

  from [ Trust-LAN trust];  >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Added with the existing zone

  to [ Untrust-ISP untrust]; >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

  source [ any 1.1.1.1/32];

  destination any;

  source-user any;

  log-start no;

Hello Sir,

if youapply # set rulebase security rules existing_policy from dmz to trust source server-D destination any action allow >>>>>>> it will only add with the existing rule [ serverA serverB serverC ServerD ],

For example:

admin@DADA# show rulebase security rules LAN-ISP

LAN-ISP {

  option {

    disable-server-response-inspection no;

  }

  from Trust-LAN;

  to Untrust-ISP;

  source any;  >>>>>>>>>>>>>>>>>>> before the change

  destination any;

  source-user any;

  category any;

  application any;

  service any;

  hip-profiles any;

  action allow;

  log-start no;

  log-end yes;

  negate-source no;

  negate-destination no;

  log-setting SYSLOG-ALL;

# set rulebase security rules LAN-ISP from Trust-LAN to Untrust-ISP source 1.1.1.1/32 destination any action allow

admin@DADA# show rulebase security rules LAN-ISP                                                               LAN-ISP {

  option {

    disable-server-response-inspection no;

  }

  from Trust-LAN;

  to Untrust-ISP;

  source [ any 1.1.1.1/32]; >>>>>>>>>>>>>>>>>>> added here

  destination any;

  source-user any;

  category any;

  application any;

  service any;

  hip-profiles any;

  action allow;

  log-start no;

  log-end yes;

  negate-source no;

  negate-destination no;

  log-setting SYSLOG-ALL;

}

Thanks

Thanks so much for your reply.  So what I should have put in my initial post was that I am actually just adding a destination.  So from the code below the destination is to two objects, but I want to add a third, so can I simply say

set rulebase security rules "to NG Sites" destination location3

Will that add the location3 to the destination and leave the current destinations there as well?  I don't want to remove any of the current destinations or configurations so want to make sure my syntax is correct.  Sorry for my earlier post, I thought I was just showing a general example but should have been more specific.

"to NG Sites" {

  option {

    disable-server-response-inspection no;

  }

  from [ DMZ1 DMZ2];

  to [ Internal];

  source any;

  destination [ location1 location2];

  source-user any;

  application [ dns http-audio soap ssl web-browsing];

  service application-default;

  hip-profiles any;

  log-start no;

  log-end yes;

  negate-source no;

  negate-destination no;

  action allow;

}
