Option -D
You are using at least SAProuter version 36.7, which is version 36, patch level 6.
The section Installing SAProuter describes where you can find the latest SAProuter.
With this option you can set the IP addresses so that they are not broken up by incoming connections in the SAProuter.
This can result in better performance for SAProuters, with which connections from many different clients are established. However, if this option is used, only the IP addresses are visible in the log (client-side).
