[Serusers] Changing the destination port

[Bruno Machado]

Hi all
 
 We are trying to install a firewall in our structure. The problem is: the firewall (between X.Y.Z.A and X.Y.Z.B)  manipulates the packets, but it changes de SRC port when it sends to the SER (X.Y.Z.B).
 
 
 X.Y.Z.A:5060 ----> X.Y.Z.B:5060
 (dump in X.Y.Z.A)
 
 X.Y.Z.A:10080 ----> X.Y.Z.B:5060
 (doing a dump in X.Y.Z.B)
 
 
 When X.Y.Z.B answer to X.Y.Z.A, it uses the port 10080:
 X.Y.Z.B:5060 ----> X.Y.Z.A:10080
 
 It break the comunication, because X.Y.Z.A isnt listening at 10080.
 I need to force the SER to send the messages back to 5060. There are any way to do it?
 
 Thanks a lot.
 
 Bruno Machado
