• Mismatched IKE/ESP parameters: ensure Phase 1 (IKE) and Phase 2 (ESP) algorithms and Diffie-Hellman groups match between client and gateway.
• NAT traversal issues: enable NAT-T (UDP 4500) if the client is behind NAT.
• Firewall blocks: ensure UDP 500 and UDP 4500 (for NAT-T) and the protocol ESP (IP protocol 50) are allowed where required.
• Certificate problems: verify certificate trust chain, validity dates, and that private key permissions are correct.
• Logs: check client logs and Zyxel gateway logs for error codes (e.g., authentication failed, no proposal chosen, or peer unreachable).
• Update software/firmware: ensure both client and gateway run supported, up-to-date versions to avoid incompatibilities and known bugs.
