I enabled NCC Discovery , but the Zyxel Device is still in standalone mode.
Make sure your Zyxel Device is registered to the NCC.
The Zyxel Device is already registered with NCC, but it is still in standalone mode; it cannot
connect to the NCC.
1
Make sure that NCC Discovery is enabled (see Section 9.4 on page 74 ).
2
Check your network’s firewall/security settings. Make sure the following TCP ports are allowed: 443, 4335,
and 6667.
3
Make sure your Zyxel Device can access the Internet.
4
Check your network’s VLAN settings (see Section 9.3 on page 71 ). You may have to change the
Management VLAN settings of the Zyxel Device to allow it to connect to the Internet and access the
NCC.
Note: Changing the management VLAN and IP address settings on the Zyxel Device also
pushes these changes to the NCC. Do this only if your device cannot otherwise
connect to the NCC.
5
Make sure your Zyxel Device does not have to go through network authentication such as a captive
portal, If your network uses a captive portal, the network administrator may have to create a new VLAN
without this requirement. Change your Zyxel Device’s management VLAN settings as necessary.
Some features I set using the NCC do not work as expected.
1
Make sure your Zyxel Device can access the Internet.
2
Check your network’s firewall/security settings. Make sure the following ports are allowed:
• TCP: 443, 4335, and 6667
• UDP: 123
3
After changing your Zyxel Device settings using the NCC, wait 1-2 minutes for the changes to take
effect.
I can only see newer logs. Older logs are missing.
When a log reaches the maximum number of log messages (see Section 1.4 on page 18 ), new log
messages automatically overwrite the oldest log messages.
