You need to configure your firewall properly. With a firewall, you can define what types of packets can create a state entry on the firewall. Typical is syn, syn ack. Even if there is no state entry, a new packet should create a new state (not be dropped). If a new packet does not create a new state, change the firewall rules so that it does. A network dump will tell you what type of packet is going out; the firewall logs should tell you what type of packet was rejected.
I could see that this would be a problem if the midtier servers were behind a NAT. Is this the case?
