it happened after a windows update i think im not sure about it i tried unistalling the updates but its still not working what can be the issue?
Hi,
What is the forticlient version.
Can you try reinstalling the FCT
hello,
its the latest version 7.4.1, i unistalled it and installed back again didnt work
Is this also affecting your traffic flow via the ssl vpn
its only happening on IPSEC VPN, i tried ssl vpn its working normally
can you collect ike debug while connecting the VPN.
diagnose debug console timestamp enable
diagnose vpn ike log-filter dst-addr4 10.10.100.109 ---> 10.10.100.109 is the remote gateway
diagnose debug application ike -1
diagnose debug application fnbamd -1
diagnose debug enable
Note: Starting from FortiOS 7.4.1, the 'diagnose vpn ike log-filter dst-addr4' command has been changed to 'diagnose vpn ike log filter rem-addr4'.
diagnose vpn ike log filter rem-addr4 10.10.100.109
diagnose debug application ike -1
diagnose debug application fnbamd -1
diagnose debug console timestamp enable
diagnose debug enable
diagnose debug disable
im not getting anything useful from it
can you let me know what was the recent windows update?
Is it KB2693643?
no i checked and it was't installed on the machine, also i tried to uninstall the latest updates of windows and it still didn't work. what happened is it was working properly up untill 13/11/24 thats the last time that the client used it so i tried to unistall every update from 13 till now.
Can you confirm one thing if NAT-T is enable on the Forticlient configuration.
Open your forticlient and see the Phase1 settings
