    What about USG series, like USG1100 & USG2200?? Are these devices safe against the above vulnerabilities?

    They have no successors in the company's portfolio.

    Hi,

    have someone problem with IPSec IKEv2 VPN connection in Windows 10 (Windows 11 no problem) ?

    I have one customer have problem after the firmware update (USG Flex 200).

    No errors in logs, after 30 seconds of negotiation between the PC and the firewall the connection is disconnect and we have this message.

    L2TP VPN connection in the same PC is working.

    Have updated to this release and we look to be seeing a possible memory leak or high memory usage that results in SSL VPN connections randomly dropping. Only resolution is to then reboot firewall and usage returns to approx. 50%

    Has anyone else experienced issues with high memory usage and/or leaks?
