ZyWALL 5 Support Notes

L15. Can I create self-signed certificates in addition to the default one?

Yes, you can create self-signed certificates of your own by selecting self-signed category when
creating My Certificates.
L16. Will Self-signed certificate be erased if I reset to default configuration file?
Yes, the original Self-signed certificate will be erased. But ZyXEL appliance will create a new
self-signed certificate at it's first boot-up time after resetting the configuration. But the new
self-signed certificate is different from the original one. So users also need to export the new
self-signed certificate to appliance's peer if they would like to use PKI for VPN.
L17. Will certificates stored in ZyXEL appliance be erased if I reset to default
configuration file?
Yes, My Certificates, Trusted CAs' Certificates, and Trusted Remote's Certificates will be totally
erased after erasing configuration files. Users need to enroll My Certificates and import Trusted CA's
certificates & Trusted Remote's certificates again.
L18. What can I do prior to reset appliance's configuration?
You can export Trusted CA's certificates and Trusted Remote's certificates before resetting
configuration to the local computer. Then import them back to ZyXEL appliance.
L19. If I export My Certificates from ZyXEL appliance, save them locally, and then
import them back after resetting the configuration file, can I reuse the imported My
Certificates ?
No, you can't reuse them. Each certificate stored in My Certificates has corresponding private key.
When you erase the configuration, the corresponding private keys are also deleted. So you can't reuse
the certificates by importing them afterward.
