![]() ![]() Performed a collect of GPClient logs from Windows laptop and searched in PANGPS.log for " Trying to do IPsec" found that this was generating failed to receive keep alive, then followed by Disconnect udp socket, then few lines down we see ipsec failed to start then we see IPSec fallback reason is IPSec connection failed. The message that is shown, is because GlobalProtect client is failing back from IPSec to SSL for the VPN connection. When GlobalProtect client will try to connect, first, it will try to connect over IPSec, using UDP, the faster protocol, if this fails, then GlobalProtect will fallback to SSL, over TCP, the slower protocol. To change this on the Portal, go to Network tab>GlobalProtect>Portals>choose the Portal>from GlobalProtect Portal Configuration screen, click on Agent>select relevant option under Configs>click on App tab>the option is called "Display IPSec to SSL Fallback Notification" by default this is set to Yes, change to No>click on OK>click on OK again>repeat for any other Portals where this change is required>Commit changes to Panorama or to the Firewall as required to suppress message as needed.Īs mentioned from user Emr_1 to suppress this message, this needs to be disabled from the Gateway, from Network tab>GlobalProtect>Gateways>Agent>under Tunnel Settings tab, uncheck the Enable IPSec>repeat for any other Gateways where this change is required>Commit changes to Panorama or to the Firewall as required to suppress message as needed.Īnother point to consider, which I ran into, is whether or not you are having issues with GlobalProtect traffic dropping IPSec connections, using UDP Port 4501. Still seeing this after activating 5.2.6 from PAN-OS 8.1.6 and running GlobalProtect Version 5.2.6-87. ![]()
