ZyWALL USG 20/20W User’s Guide
735
The ZyWALL 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 cannot get the RADIUS server to authenticate the ZyWALL‘s default admin
account.
The default admin account is always authenticated locally, regardless of the
authentication method setting. (See Chapter 37 on page 573 for more information
about authentication methods.)
The ZyWALL 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 ZyWALL 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 Chapter 37 on page 573 and
Chapter 38 on page 583, respectively.)
I cannot add the admin users to a user group with access users.
You cannot put access users and admin users in the same user group.
I cannot add the default admin account to a user group.
You cannot put the default admin account into any user group.
The schedule I configured is not being applied at the configured times.
Make sure the ZyWALL’s current date and time are correct.
