SSL-VPN automatic resolution screen not working after 7.0.4 firmware upgrade

After updating, all our SSL-VPN RDP clients complained because their session stopped auto-scaling the resolution on their browser. Have someone found a way to make this unintended behaivor stop? We could not find any way to made it like it was befor patching. We were specting that 7.0.5 could fix it but i dont see any mention in the log page...

Found how to solve this. You must go in to each SSL VPN Portal and set the Width and Height to 0. 



FIREWALL (web-access) # show full-configuration | grep window
set default-window-width 1024
set default-window-height 768

FIREWALL (web-access) # set default-window-width 0

FIREWALL (web-access) # set default-window-height 0

FIREWALL (web-access) # end


Then you must change your bookmarks to 0 and 0 for height and width and full screen works again.

Hello, I found how to solve my issue (seems like a bug):

  1. from SSL-VPN-Portals, select your portal, then click on "Edit in CLI"
  2. remove the reference to width and hight :


config bookmark-group
edit "gui-bookmarks"
config bookmarks
set width 0
set height 0



  • Click again on "Edit in CLI"
  • Add the default-window-width:


set default-window-width 0
set default-window-height 0


  • Then, I had to click on "Cancel" (not "OK"). If I click on "Ok", my changes are not taken into account.

See for more informations.

I figured out one time but couldnt replicate the fix later, this solves the issue, thank you DTG-POLE-ARCHI.


And yes, I also assume this is a bug.

I've got the same problem, but when I list configuration with grep window I got :

set default-window-width 1024
set default-window-height 768

set default-window-width 1024
set default-window-height 768


But when I send : set default-window-height 0

Unknown action 0


My Firmware version is 7.2
