PA200 Dynamic DHCP Client Issue

[ccaruso]

I am running a PA200 at home with Verizon FiOS.  Currently the software is at version 4.1.6.  I currently have everything running correctly, but the DHCP lease for the WAN expires every 2 hours.  I watched the interface this evening to see what is happening, and about 1 hour in the state changed from "bound" to "renewing", but it never renews unless I manually click new.

This causes me to lose internet access every two hours.  If I log into the box, and click renew on the WAN interface, I am back up and running.  Does anyone know why this is occuring??  Is this a bug within the software??  If this is not a bug, has anyone ran into this issue and found a workaround?

Thanks for any help you can provide!

I guess I didn't look hard enough before asking this question, I found this post https://live.paloaltonetworks.com/message/15473#15473, so I will upgrade the software and see if that helps to fix the issue.

Hello ccaruso, We recommend upgrading to PAN-OS 4.1.10 to address this issue.  You may have been affected by the following addressed issues:

• 46477 – The DHCP client on the firewall was sending an invalid option (option 54) in its renewal requests, causing the DHCP server to ignore the requests. This issue has been resolved.

• 40137 – The firewall was not able to renew its DCHP settings with certain ISP network connections. In this case, a Verizon FiOS connection was in place and during a DHCP refresh that occurred every hour, the request timed out. Issue was due to an interoperability problem between the firewall’s DHCP client and the DHCP services on the ISP network, which has been resolved in this release.
