# Wrong interface names on the 9400 appliance

**Product**: Check Point Appliances  
**Version**: R81.20  
**OS**: Gaia  
**Platform**: 9000  
**Last Modified**: 2024-06-03

## Symptoms

- On a 9400 appliance in the Security Gateway configuration (non-Maestro) that runs with the R81.20 **Take 781** image (see [sk181698](https://support.checkpoint.com/results/sk/sk181698)),

or after installing the R81.20 Jumbo Hotfix Accumulator Take 54, the interface names are mixed as follows:
  
  - eth1 (Port 1) is called eth3  
  - eth2 (Port 2) is called eth4  
  - eth3 (Port 3) is called eth1  
  - eth4 (Port 4) is called eth2

After installing the R81.20 Jumbo Hotfix Accumulator Take 54, the IP address that is configured on the interface eth1 (Port 1) is assigned to Port3.

- On a 9400 appliance in the Maestro configuration that runs with the R81.20 **Take 783** image (see [sk181698](https://support.checkpoint.com/results/sk/sk181698)), the interface names are mixed as follows:

- ethsBP0-01 (Port 1) is called ethsBP0-03  
  - ethsBP0-02 (Port 2) is called ethsBP0-04  
  - ethsBP0-03 (Port 3) is called ethsBP0-01  
  - ethsBP0-04 (Port 4) is called ethsBP0-02

This issue does not affect Maestro functionality, except for the monitoring and verifier tools.

Installing the R81.20 Jumbo Hotfix Accumulator Take 54 does not resolve the issue.
