If you have uploaded a logo to show on the SSL VPN user screens but it does not display
properly, check if the logo graphic is in GIF, JPG, or PNG format. The graphic should use a
resolution of 103 x 29 pixels to avoid distortion when displayed. The ZyWALL/USG
automatically resizes a graphic of a different resolution to 103 x 29 pixels. The file size must
be 100 kilobytes or less. Transparent background is recommended.

If users can log into the SSL VPN but cannot see some of the resource links, check the SSL
application object's configurations.

If the ZyWALL/USG redirects the user to the user aware screen, check whether the user
account is included in an SSL VPN access policy or not.
5
If you have changed the HTTP/HTTPS configuration, the SSL VPN network extension sessions
will be disconnected. The sessions need to be reconnected if this happens.
