Hi, Couple of months back there was a change made to the update server and an annoucement was sent out which states the following Reminder: Palo Alto Networks Update Server Change Notification on 10/5/12 Created by panagent Sep 27, 2012 Palo Alto Networks is rolling out a CDN-based update infrastructure. As a result, content updates throughout the world will be delivered from the closest server to the device. If you have firewall rules that restrict the hosts that your devices can reach, you will need to adjust your firewall policy as follows. The current static IP address, 67.192.236.252 will be retired on October 5, 2012 and updates.paloaltonetworks.comwill begin to leverage our CDN infrastructure. A new static host is now available at staticupdates.paloaltonetworks.com with an IP address of 199.167.52.15. You will need to adjust your firewall rule to reflect the new IP address or hostname and you will need to change the update server address that is configured on the device to staticupdates.paloaltonetworks.com. Refer to Palo Alto Networks Devices Require FQDN For Update Server. This change can be made anytime prior to October 5 to achieve no interruption of update services. It is recommended that users who do not have requirements to restrict the hosts your devices can reach, leave the update server configuration as updates.paloaltonetworks.com. If no change is made to the configuration, devices will begin to take advantage of the new CDN infrastructure on October 5, 2012. Have you made the change according to the above mentioned announcement. If it is not the above issue then please check your traffic logs if it is blocking anything while you are trying to do the update. Hope this helps. Thank you Numan
