multiple Palo Alto Agent deployments

OCDBE — Tue, 22 Feb 2011 16:07:57 GMT

Hello

We are having some complaints with the deployment of multiple Palo Alto Agents.

We have 3 remote sites in 1 DOMAIN which are connected with a slow vpn connection. Each remote site has his own Domain controller

Since we have a slow connection ,we made the choice to deploy an agent for each site. Each agent is only pointing to the local domain controller . The Palo Alto Device ( located at the main site ) is pointing to all agents.
the issue is that some user mappings are not recognized by the PA , but they are listed on the agent.

Question about this: We thought the Palo Alto is demanding all configured Agents for the same domain to resolve an ip-address to a username , but it seems like the Palo Alto device is only demanding the active agent ( * ) ( show user pan-agent statistics )

Is there anyone who can confirm this ?

If the Palo Alto agent will only demand the active agent , how can we workaround this issue ? ( if we define each DC's on the remote agents, we got to much traffic load on the vpn connections. )

Thanks !

The *connected Pan Agent server is the one that is being polled for user/group membership updates. The PAN firewall should be pulling user/ip mappings from all of the agents.

What version of PANOS are you running on the firewall?

Are you seeing that the activity columm for 'show user pan-agent statistics' is only updating for the *connected Pan Agent server?

Hello,

we see updated information for every agent when we check with the cli ( every agent is connected and the right amount of users / groups is displayed every time ) , but if we enable the debug logs on the agents ,we never see an incoming connection from the Palo Alto , only on the active agent... We use 3.1.7...

If the activity column is incrementing for all Pan Agents (show user pan-agent statistics) but the Pan Agents do not show a connection from the PAN firewall in their logs then it sounds like something is not working properly. I would verify that the scenario you describe is true and if so I would advise you to open a support case.
