AD Audit Plus and NAT Communicaton

AD Audit Plus and NAT Communicaton

Has anyone been successful in setting up the NAT configuration between AD Audit Plus and another public facing server?  We use Endpoint Central for all our deployments and it uses its own NAT through a secure gateway to communicate to our remote devices.  We are trying to set up the NAT in AD Audit Plus to communicate through the same server but it fails to connect no matter which port we try. I can't have AD Audit Plus be its own NAT for security reasons.  I've worked with support but we can't seem to find the answer.  Any insight would be helpful.
