difference zone between end users and domain controller on Palo alto

Hello all,

 

I have a problem with palo alto PA-850. I configure domain controllers and end users diference zone. example: zone name: Server for domain controllers, and zone: User for end users.

 

I setup policy to allow all traffic from Zone: Server to Zone: User and from User to Server. but end users could not authenticate with domain controllers.  I checked in traffic logs: To-Port: 135, 445, Aplication: Incomplete. Please help to advise

 

thanks

Hi @Chivas,

 

Try following the packet with PCAPs (is the server actually getting the packet ? Is the server returning the packet correctly ?)

hi Kiwi,

 

I checked in PCAPs, the server is not getting the packet. but from client, I can ping or tracert to the server, even access network share on the server. just cannot authenticate when end users login. Please help to advise, do I need to configure any thing

 

the rule i setup:

 

active-directory {

         source zone: User;

        source  address: any;

        user any;

        destination zone: Server;

        destination address: any;

        category any;

        application any;

        service any;

        action allow;

}

 

thanks

@Chivas,

What if you actually look at the session ID in the CLI; does that give you any additional insight. Your security policy looks fine as the only thing you are really doing is analyzing the zones.

Hello,

Application incomplete in my experience has been a routing issue. If they are on different subnets, e.g. useres and servers, make sure the routes are in place.
