Scenario :

Users may not establish the IPsec remote VPN connection with the Nebula firewall successfully due to the DNS names of certificates are different. This article will guide you on how to check the DNS names of certificates on the firewall.

Answer :

Navigate to Site-wide > Configure > Firewall > Remote access VPN to find a Domain name for remote VPN usage. Use the CLI "show ca category local" on the device to check if the domain name matches the Nebula page.

If the DNS names are different, reboot the firewall to synchronize the certificates. If this doesn't resolve the issue, please contact Zyxel support for further assistance.
