Unable to connect to the Financial Reporting Studio

We are currently having issues connecting to the Financial Reporting Studio in our test environment, however, we are able to connect in our production environment.  We have tried to compare both environments, however, so far, we have not been able to come up with anything.  Our test web server is behind an F5 load balancer.  The address behind the F5 has a 10 address and the address outside the F5 has a 172 address which nats back to the 10 address. 

I have put a trace on my pc when trying to connect to the FRS in our test environment.  What the trace shows is that it is hitting the 10 address instead of the 172 address and it is erroring out because it cannot reach back to my pc.  It is supposed to just hit the 172 address as it is in production.  Does anyone know if the IP address information is stored anywhere in the application or the database?
