How do I force Digi PortServer TS4 to connect to a specific server?

I have two SCO OpenServer servers on my network, one with IP 10.10.0.2 and the other with IP 10.160.99.27.

All of our PortServer TS4’s are pointing to the 10.10.0.2 server with a “DEST=10.10.0.2” configuration setting.

They have sometimes incorrectly connected to the 10.160.99.27 server instead.

What do I have configured wrong where they can even see the 10.160.99.27 server?
