And the exact problem I am having is that the Dynamics NAV SQL Server and the RDS server when both put on Pertino were routing all traffic over Pertino instead of locally. I took the SQL server out of the network (made its own network) and everything started working again.
What Pertino is waiting on me for is some packet captures that I have not had time to create.
Because I seen odd behavior of LAN devices without Pertino also having problems access SQL. Those devices have the NAV client locally installed.
