ZyXEL Communications ZyWall 110 User Manual page 1035

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
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.
I configured application patrol to allow and manage access to a specific service but access is
blocked.
• If you want to use a service, make sure the security policy allows UTM application patrol to go through
the Zyxel Device.
I configured policy routes to manage the bandwidth of TCP and UDP traffic but the bandwidth
management is not being applied properly.
It is recommended to use application patrol instead of policy routes to manage the bandwidth of TCP
and UDP traffic.
I cannot get the RADIUS server to authenticate the Zyxel Device's default admin account.
The default admin account is always authenticated locally, regardless of the authentication method
setting.
The Zyxel Device fails to authentication the ext-user user accounts I configured.
An external server such as AD, LDAP or RADIUS must authenticate the ext-user accounts. If the Zyxel
Device tries to use the local database to authenticate an ext-user, the authentication attempt will
always fail. (This is related to AAA servers and authentication methods, which are discussed in other
chapters in this guide.)
I cannot add the admin users to a user group with access users.
