Hi all, I am back from vacation!
This morning I attempted to remove M$ Proxy Server from the Exchange box and reconfigure TCP/IP settings. The Exchange box is now fully functioning behind the Dachstein router as originally intended. Note: the box had to be rebooted for the gateway address change to take effect. Not necessary for a name server change. Next project- spam/virus filtering system that sits between the router and the Exchange box.
