Question Windows using wrong outbound ip - Always the primary ip

[EHCanadian83]

I have 1 network card.
The network card has a /29

The OS is windows.
The OS is using built in firewall and the port is permitted.

The problem is that the machine always uses the 1st ip configured for outbound ipv4.
Even if the application is bound to one of the /29
If I set xxx.xxx.xxx.116 as the 1st ip then the remaining it will use xxx.xxx.xxx.116

So per example.
xxx.xxx.xxx.113 - gateway
xxx.xxx.xxx.114 - bound primary
xxx.xxx.xxx.115 - bound
xxx.xxx.xxx.116 - bound
xxx.xxx.xxx.117 - bound
xxx.xxx.xxx.118 - bound

I have xxx.xxx.xxx.116 bound with named/bind both listening and server option set

The master is seeing xxx.xxx.xxx.114 requesting the zone transfer and not xxx.xxx.xxx.116

Why is this?

Appears to be homework.

Provide/post what you believe is the "why" and support that belief accordingly.
