Refresh FQDN failed

L1 Bithead

Hi guys,

 

I have a big problem.
My PA failed in refresh fqdn task and now the PA can't resolve Fqdn object.

My dns Setting are good and there is no drops between PA and DNS server.

 

Any advices?

 

Thank you!

Hi Erez,

 

To start, you may want to check if the firewall is receving a response for the DNS queries by taking a pcap.

Check if the DNS service route is via MGT or data interface and take tcpdump (MGT) or DP capture (Monitor > packet capture)

 

Check the service route for DNS :

Thanks,

Thank you,

The DNS service route is via MGT.

I did Tcpdump from DNS server (tcpdump filter "src net dns server")

and then force refresh fqdn

this is the result:

8517 packets received by filter
0 packets dropped by kernel

 

This is ok no?

 

Hi Erez,

 

You need to open the pcap (SCP/TFTP to a computer to view using Wireshark) and check if the DNS req. and response are seen with the DNS response having the answer to FQDN(s) configured.

Hi,

10.24.15.35 is our pamorama machine but we didn't using the machine.

Hi,

Just confirm you can ping your DNS servers from the Palo through the CLI. Take few FQDN and try to see if you are getting a resolution, not from the Palo device, just use different PC.

What PAN-OS are you running? After 6.1.x you can change refresh time to 600 seconds instead of 1800.

If the device fails to get FQDN info during a refresh period, the firewall will not retry immediately. The firewall will wait for the new refresh period time.

 

> configure

# set deviceconfig system fqdn-refresh-time <600-14399>

# commit
