ZyXEL Communications ZyWALL 110 User Manual page 778

I changed the LAN IP address and can no longer access the Internet.
The ZyWALL/USG 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 ZyWALL/USG.
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 ZyWALL/USG's default admin account.
The default admin account is always authenticated locally, regardless of the authentication method
setting.
The ZyWALL/USG 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/USG 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.
You cannot put access users and admin users in the same user group.
