Global Protect disconnects several times a day

L1 Bithead

Our VPN users are complaining that after being connected for over 1 hour they get disconnected by global protect.  They have to close global protect and reopen to connect back.  We have remote customer service agents that get disconnected up to 4 to 5 times a day. We are running global protect version 2.3.3-5.   We have opened a ticket with support and have escalated and had no success.  Anybody else having this issue?   Any luck getting resolved.

what type of firewall and version of PanOS would help as well


I am not experiencing, but I have not upgraded my users to 2.3.3 because I am (still) waiting for a better upgrade and delivery system.



3020s running 7.0.3

I would try upgrading to 7.0.4, much better "production" release.

86803 Fixed an intermittent issue where the idle timer for GlobalProtect IPSec tunnels either did
not expire appropriately (such as when the tunnel was torn down) or expired at the
configured idle time expiration even when a user was actively using the connection. With
this fix, the GlobalProtect IPSec tunnel idle timer behaves as expected.


It is fixed in 7.0.4 and 6.1.8 (allthough it isn't mentioned in the 6.1.8 release document)


Can confirm it is working on 6.1.8 and 7.0.4, you should REALLY upgrade to the 7.0.4 release, it is night and day in comparison to the 7.0.1-7.0.3 releases.



We upgraded to 7.0.4 on 1-9-2016 and still having problems with global protect disconnects.  Any other ideas?

sure there isnt an issue with the Internet or something down the line along their route to using VPN?

This is affecting several customer service agents that work from their home in different parts of the US.  It has been escalated to Palo Alto engineering now.  Still no resolution.

From the logs on the client I see that the service sees a packet that seems to corrupted and this causes the service to close the connection.

Everytime we close out the connection, it is because of this packet that we see. On the firewall I see that the client disconnects with the firewall.


As of now Support nor Engineering has an answer.
