I have added support for IPv6 in Red Hat 8.0. At the beginning it seemed to work fine, but I was trying to communicate two processes within my machine, so ipv6 packets didn´t really go to the network. When I tried to communicate with other machines I realized that the UDP port used to send packets to the network was not the port that I told the application to reserve. The application is written in Java and is also running in a Solaris system without any kind of problems.

Could anyone tell me why the used UDP port doesn´t match the port I order to reserve?? Do I have to make some special configuration for this?? Does IPv6 support for RH 8.0 hava any known bug???
