Hi all<br> <br> 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)&nbsp; manipulates the packets, but it changes de SRC port when it sends to the SER (X.Y.Z.B).<br> <br> <br> X.Y.Z.A:5060 ----&gt; X.Y.Z.B:5060<br> (dump in X.Y.Z.A)<br> <br> X.Y.Z.A:10080 ----&gt; X.Y.Z.B:5060<br> (doing a dump in X.Y.Z.B)<br> <br> <br> When X.Y.Z.B answer to X.Y.Z.A, it uses the port 10080:<br> X.Y.Z.B:5060 ----&gt; X.Y.Z.A:10080<br> <br> It break the comunication, because X.Y.Z.A isnt listening at 10080.<br> I need to force the SER to send the messages back to 5060. There are any way to do it?<br> <br> Thanks a lot.<br> <br> Bruno Machado<br> <p>__________________________________________________<br>Faça ligações para outros computadores com o novo Yahoo!
