Question:
After updating the firewall to firmware version 5.40, SSH Forwarding no longer works. Is it possible to re-enable it?
Answer:
SSH Forwarding was disabled starting from ZLD 5.40 due to a vulnerability fix. In these firmware versions, AllowTcpForwarding is set to "no" by default for security reasons. Unfortunately, there is no configuration option or CLI command available to manually re-enable this feature. This change was made to enhance overall system security and prevent potential risks associated with the feature.
