    Today I did the update on the ZLD 4.35. Since then I can perform several settings such as changing Firwall rules only via the Easy Mode. That is not practical...can i change this feature???

    Hi @Wolfgang,
    4.35 is a new release includes new features. To understand if your device is proper to upgrade to the 4.35 or not, you may need to review the purpose why you upgrade your device firmware to 4.33WK35 since some later fixes may not be included in the 4.35 in time because of 4.35 release schedule. For more information, you can refer to the release note. 
  • Hello,

    i just have upgraded one of three Zywalls. After a fluent upgrade process the Zywall came up like normal, but: I was not able to connect via VPN from the outside. Going back to 4.33 brought the working VPN back!! Has anybody else seen the same issue?

    Hi @Robertm,

    I load your configuration our ZyWALL 1100 to run the test.

    What I modified in the configuration file is:

    1. ge1 IP address

    2. Add a local user "emily" and move it to the group for L2TP VPN "vpn-user-gruppe"

    Other settings remain the same as yours.

    First, I use firmware 4.33 WK35 to run the test. L2TP VPN is connected from iPhone.

    Then upgrade ZyWALL 1100 to 4.35 and iPhone is still able to build L2TP VPN.

    Here are the screen shots for your reference.

  • Hi @Zyxel_Emily

    I got the same problem like @Robertm!

    I tried to use a local user on the zyxel and it worked for one time, after that it just didn't accept my credentials.

    Hi @Kauzig,

    We need the configuration file to check the symptom. I've contacted you in private message for more information.
