The problem is that app B is replying back directly to app A as they're on the same subnet. However, app A didn't initiate a connection to app B. It opened a connection to the virtual server IP. So app A ignores app B's response.
If you're only using the virtual server for internal clients, you could enable SNAT automap on the virtual server so that LTM translates the source address to its IP address on requests to the pool for the virtual server. This ensures that the apps respond back to LTM.
If you only want to apply SNAT when the source and destination hosts are on the same subnet, you could use an iRule:
