No. On the application layer, you do not know anything about the IP address used for your external communication. This is handled automatically by the kernel. Basically, the outgoing communication shows the very same IP address than the incoming connection if the remote site set up the connection. For outgoing connections, the main IP address would be used. I do not know if this can be changed.
