Chapter 56 Troubleshooting
If you have the Configuration > VPN > IPSec VPN > VPN Connection
screen's Use Policy Route to control dynamic IPSec rules option enabled,
check the routing policies to see if they are sending traffic elsewhere instead of
through the VPN tunnels.
I uploaded a logo to show in the SSL VPN user screens but it does not display
properly.
The logo graphic must be GIF, JPG, or PNG format. The graphic should use a
resolution of 127 x 57 pixels to avoid distortion when displayed. The ZyWALL
automatically resizes a graphic of a different resolution to 127 x 57 pixels. The file
size must be 100 kilobytes or less. Transparent background is recommended.
I logged into the SSL VPN but cannot see some of the resource links.
Available resource links vary depending on the SSL application object's
configuration.
I logged into the SSL VPN but cannot perform some actions in the File Sharing
screen.
The actions that you can perform in the File Sharing screen vary depending on
the rights granted to you in the SSL application object's configuration.
I can no longer find some of my original files in the SSL VPN File Sharing
screens, there are only newer files with the same name.
Uploading a file with the same name and file extension replaces the existing file on
the file server. No warning message is displayed.
I cannot download the ZyWALL's firmware package.
The ZyWALL's firmware package cannot go through the ZyWALL when you enable
the anti-virus Destroy compressed files that could not be decompressed
