The source number is always fixed on outgoing connections, but it's up to the application to specify if it wants to use an IP address other than the primary. You may want to look at the manpage for 'jail' as it allows you to create virtual machines where the primary IP of the virtual machine is different from the primary of the whole box. -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] "I have the heart of a child; I keep it in a jar on my desk."
