The VPN connection is up but VPN traffic cannot be transmitted through the VPN tunnel.
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 103 x 29 pixels
to avoid distortion when displayed. The Zyxel Device 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.
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 cannot download the Zyxel Device’s firmware package.
The Zyxel Device’s firmware package cannot go through the Zyxel Device when you enable the anti-
malware
Destroy compressed files that could not be decompressed
option. The Zyxel Device classifies
the firmware package as not being able to be decompressed and deletes it.
You can upload the firmware package to the Zyxel Device with the option enabled, so you only need
to clear the
Destroy compressed files that could not be decompressed
option while you download the
firmware package. See
for more on the anti-malware
Destroy compressed
files that could not be decompressed
option.
I changed the LAN IP address and can no longer access the Internet.
The Zyxel Device automatically updates address objects based on an interface’s IP address, subnet, or
gateway if the interface’s IP address settings change. However, you need to manually edit any address
objects for your LAN that are not based on the interface.
