Issue with 1:1 NAT Functionality after Upgrading from 2.6.x to 2.7.2 in HA CARP Setup

[empbilly]

Hi,

We have 2 appliances in HA CARP. After upgrading from version 2.6.x to 2.7.2, the 1:1 NAT we have stopped working. I read the release notes for versions 2.7.1 and 2.7.2 and didn't find anything that could affect it.

Points I checked:

• The virtual IP seems to be correct initially;
• The 1:1 NAT is also correct, as we used in the previous version 2.6.x;
• There is a firewall rule allowing traffic to the private IP;
• I tested packet capture for both public and private IPs, but nothing is captured.

Any suggestions?
