## Symptoms

- * "`NAT Hide failure - there are currently no available ports for hide operation`" drop logs in SmartView Tracker for connections originated from the Standby cluster member (e.g., pings to a host).

* Kernel debug ('`fw ctl debug -m fw + drop`') on Standby cluster member shows that some connections are dropped:  

  `;fw_log_drop_ex: Packet proto= ... dropped by fw_first_packet_xlation Reason: NAT rulematch failed`

* `/var/log/messages` file on Standby cluster member is filled with these messages for different port numbers:  

  `;FW-1: internal error - invalid port allocation range, low_first: ..., low_last: ..., high_first: ..., high_last: ... extra_first: ..., extra_last: ..., mem index: 0, cluster size: `*N*` ;`

## Cause

Invalid values are assigned to kernel parameters '`fwx_low_port_quota`' and '`fwx_high_port_quota`', if the configured values are too large for either kernel parameter.

As a result, Hide NAT ports are exhausted on Standby cluster member.
