Default Routing internal requests to external IPs

Hey everyone. Does anyone have a good resource/idea about how to solve the following issue for a client of mine?

They have an mobile device that switches from mobile network to wifi when wifi is available. An external IP is being used as an alias on the firewall to route incoming traffic to an internal mail server. The problem is that when the mobile device is used in the office, the device tries to access the external IP and fails to connect.

I know that there is something that stops internal requests to external IPs that route back to an internal machine from working from within the network.

Right now the solution is to turn off the wifi in the office and force the phone back on the mobile network to connect.

Is there a way to analyze outgoing requests and route them directly to an internal machine?

My client would like to be able to leave the wifi setting as is and take advantage of the speed.
