Enable Syslog over TLS | Use Syslog over TLS to securely send logs from the Zyxel Device to the syslog server using TLS encryption. On the Zyxel Device, first generate a certificate for syslog authentication of the Zyxel Device. The CN (Certificate Name) must match the IP address of the Zyxel Device's interface to the syslog server. Go to Certificates > Local CA and import a certificate for syslog authentication. This is required. |
Local Certificate Used by Syslog Client | Optionally, the Syslog server may also request a certificate from the Zyxel Device for mutual authentication. Go to Certificates > Local Certificate and import a Zyxel Device certificate that the syslog server can use to verify the Zyxel Device. |
