BPA working for some config but not for others

Hi,

 

I'm running Expedition 1.0.105 with BP rules version 3.2.0 and while the analysis in working some FW configs, I've got some other FW configs for which nothing happen. I'm, of course, able to import the config in the tool and browse it

but when I click on "Start Analysis", I see the progression bar but no result.

 

Is there any special place in which I could see logs and understand what's wrong?

Re: BPA working for some config but not for others

After a relink of Python to Python 3.6 instead of 2.7 and a reinstall of the apt_pkg package, it still not working with one of the two configuration file with these errors in the Apache error log file:

Traceback (most recent call last):

I really don't undertand why only one of the config files is triggering this.

Re: BPA working for some config but not for others

As the error log was referring to global_protect.py, I played with the GP part of the configuration and I found that the <client-auth> section of the <global-protect-portal> is the problem:

...

<global-protect-portal>
              <entry name="Test">
                <portal-config>
                  <client-auth>
                    <entry name="auth-any">
                      <os>Any</os>
                      <authentication-profile>LDAP-AP-customer</authentication-profile>
                      <authentication-message>Enter login credentials</authentication-message>
                    </entry>
                  </client-auth>
                  <ssl-tls-service-profile>Wildcard customer</ssl-tls-service-profile>
                  <local-address>
                    <ip-address-family>ipv4</ip-address-family>

...

If I remove the <client-auth> section, it's working again... while I tried some other firewall configs in which the <global-protect-portal> section is working correctly.

 

Would anyone have a crazy idea?

Re: BPA working for some config but not for others

I finally found the problem, the configuration extract comes from Panorama and is not including the Panorama profiles which means some part of the configuration was missing.

 

Two takeaways:

  1. Expedition error message could certainly by improved when a missing reference is found in the configuration.
  2. Keep in mind to extract the running-config on the firewall instead of the Panorama config. You could do that for example by using from Panorama CLI "scp export device-state device <device-serial> to username@host:path" and then, import the running_config.xml in Expedition.
