SSL VPN slower after 5.39(ABUJ.1) firmware

GrahamWebb

Hi since upgrading our Zywall USG 500 FLEX to the latest 5.39(ABUJ.1) firmware I am finding SSL VPN performance is slower. Windows file transfers over VPN are intermittantly very slow as well as saving and opening Excel files etc. Has anyone else noticed this? Also can Zyxel support let us know why the SSL VPN client is now end of life and also the EOL date forthe Zywall USG 500 Flex as I am looking at upgrade and moving to a different system for VPN.

Also it would be great if someone could repy to my question I have posted here:

Hi @GrahamWebb ,

For better tracking, we'll address your other questions in the original post.

Regarding the slow VPN file transfer issue after upgrading to firmware 5.39(ABUJ.1), please provide the following information:

1. Previous firmware version before the upgrade
2. File transfer speeds comparison:
   • Speed with previous firmware
   • Speed with current firmware 5.39(ABUJ.1)

Also, please attach your current USG FLEX configuration file for review.
