The previous blog post was more dealing with the background about having a second Notes TCP/IP port.
This post focuses to setup a new Notes port end to end using the DNUG Lab environment as an example.
The server I am configuring has two separate IP addresses on two different network cards.
But the same procedure would also work with IP addresses in the same network.
This is a companion discussion topic for the original entry at https://blog.nashcom.de/nashcomblog.nsf/dx/configure-an-addtional-notes-port-on-a-server.htm
